03-15-07, 10:53 PM
Below is a paste of my contact with them
any and all people who WILL buy, ie NO DREAMERS NO MAYBES this is YES I WILL BUY IT, they estimate about a 45 hp increase (thats what they got with the 4.6 07 DTS) and cost to be like all of their tunes, roughly 400 dollars.
I NEED THE VIN NUMBERS AND SERVICE NUMBERS FROM THE ECM OF ALL TRULY INTERESTED PARTIES!
List them below in IN THIS FORMAT PLEASE (to make it easier to follow)
thanks alot guys

YEAR: 1997
MODEL: Eldorado Touring Coupe
VIN: 1G6ET1293VU616146
SERVICE #: XXXXXXXXXXXXXXXXXXXXX (i have to look at mine i cannot right now)




EMAIL:

If you want a start on this,
have people on the forum submit to you their VIN numbers with computer Service numbers.

We need both. When it gets to the tuning point after the intitial R&D is done, we'll need a couple vehicles here.

You know I'm down. When I get my info I will post.

Odin8
03-16-07, 12:30 AM
Definately down. I'd break into my rainy day bank account if need be.

This going to remove the speed limiter on non Z PCMs? Also, where is this ECM service # and how do we get to it?

CadillacSTS42005
03-16-07, 12:44 AM
it will:
remove limiters
modify fuel curves
adjust shift points
allow for camming porting etc etc etc
you get the idea

again on a stock car they got 45HP increase..

CandyRedDHS
03-16-07, 03:25 AM
Count me in...I can picture it now me taking down everything in sight....just tell me when where and exact $$$

jadcock
03-16-07, 08:15 AM
Can they provide a dyno graph for their 45 hp claim?

Raze
03-16-07, 08:16 AM
I am soooo down :)

01STS
03-16-07, 10:30 AM
Count me in as well!! ( waves money in hand)

CandyRedDHS
03-16-07, 10:54 AM
Where can i find the computer Service numbers?

Lac_Cruising
03-16-07, 10:58 AM
Count me in. :bouncy:

CadillacSTS42005
03-16-07, 12:01 PM
if your in then do as i said
i really need to get this ball rolling please provide me with the info i asked for
the serivce number is as i said on the computer itself and it will state it is a service number THIS IS NOT THE PART NUMBER!

Jadcock= they state the claim but OBVIOUSLY b/c this is a different version of the northstar used in the DTS the numbers wont be the exact same but when it comes down to it, its the only possibility PERIOD! once this is hacked we can add cams, pistions etc etc etc to a stock car that in itself is worth it!

ejguillot
03-16-07, 03:52 PM
I will look up this info tonight and send it to you. The PCM resides by the air filter assembly on a 2000 STS, correct?

I would even put down a 20% deposit for the tune...

Edwin

CadillacSTS42005
03-16-07, 04:24 PM
correct

CadillacSTS42005
03-16-07, 04:26 PM
OK gentlemen
they have done it
however they need cars to test with
test cars will get a FREE TUNE

eldorado1
03-16-07, 04:52 PM
It only took 1 day for them to do this? What happened to "30k worth of R&D"?

Ask them for the before/after dyno on the DTS

CadillacSTS42005
03-16-07, 04:57 PM
Theyve been working with it
theyve come to the decision due to the proof i provided them about the failed supercharger project on caddy info that people really want to mod these cars
that added to the fact that they would be the ONLY source for this made it easy to convince
heres the deal
they need cars to be brought to this address:

Westers Garage
218 Centre Street
Tilley, Alberta Canada

any person who brings their car there will recieve a free tune (about 450 dollar value) more than enough to reimburse someone for driving a little ways to go there.

CadillacSTS42005
03-16-07, 05:10 PM
and the 30-40k in R&D comes from them usually buying a test car rather then find one, im trying to get this done fast and keep price down hence why we need people with cars willing to go there, to go there.

clarkz71
03-16-07, 05:37 PM
That's good news for you OBD II guys. But the 42 hp gain is only on the supercharged 4.4, they don't say what the 4.6 gains.


2007 Cadillac STS CTS-V, DTS and XLR 4.4LSupercharged, 4.6LNorthstar 4.6L RWD and LS2

(42HP and 40ft/lbs gain Supercharged)

and it lists the 4.6 Northstar there as well
im just stating what was told to me

urbanski
03-16-07, 05:55 PM
hey I PMd tbyrne, they're a Vendor here and they may sell Westers tunes. I'd feel better if a Vendor was involved in all this. Dont know, maybe they can help

clarkz71
03-16-07, 05:55 PM
and it lists the 4.6 Northstar there as well
im just stating what was told to me







I know, I just looked at the website and posted what it said, again, they list both the 4.4 SC and the 4.6 N*. And below the listing it says.. "42 hp & 40 ft lbs gain supercharged.

CadillacSTS42005
03-16-07, 06:00 PM
thanks Urb
i sent a PM to Sal requesting to speak with him but never herd back
i was going to ask if it was possible to post like an alert or something because i really need those vins can service numbers and also i wanted you guys to know about it so its not like im trying to sell anything

clark again im just speakin for what they told me not the site, we could do anything turbo s.c etc etc but in stock form we look to gain roughly 40 hp

clarkz71
03-16-07, 06:04 PM
and it lists the 4.6 Northstar there as well
im just stating what was told to me


thanks Urb


clark again im just speakin for what they told me not the site, we could do anything turbo s.c etc etc but in stock form we look to gain roughly 40 hp

You need to look at the website, 42 hp is for the Factory Supercharged 4.4 only.

http://westersgarage.eidnet.org/GM.htm

Look at the 7th listing.

CadillacSTS42005
03-16-07, 06:06 PM
again
IVE LOOKED
they have told me in EMAIL 40ish hp

clarkz71
03-16-07, 06:08 PM
I'll believe it when I see a dyno sheet. When I asked them about the memcal they already have for the 93-95 they said around 25 hp. Now all of a sudden an OBD II car can make almost double. I doubt it.:tisk:

clarkz71
03-16-07, 06:11 PM
again
IVE LOOKED
they have told me in EMAIL 40ish hp

Post a copy of the e-mail where THEY say 40 ish hp on a 96-04 4.6

CadillacSTS42005
03-16-07, 06:11 PM
again
i have no reason to lie man ive always backed up everything ive said here...
anyways i need those vins and service numbers asap guys

CadillacSTS42005
03-16-07, 06:14 PM
We'd probably need some STS cars to start with--ultimately, we always start
with the computers only--and then get in some cars to do dyno work with.
Gains are estimated at around 40 hp

ejguillot
03-16-07, 06:27 PM
Well, if they're tuning for a 2000-up FWD northstar, retuning for 93 octane makes the 40HP claim more plausible.

If I wasn't so far away from Westers (according to google maps, 2,632 miles! :eek: ) I would be willing to drive up. But the cost in gas alone (5,400 mi round trip / 25mpg = 216 gals * 3$/gal = $648) would be too much, let alone food and lodging.

600 miles? I would do it, and just take a few days off work. But 2,600+? No can do, but I'll be among the first to buy the tune.

The PCM is IN the airbox, at least on 2000 - 2005. This sounds tempting. I would like to know that it's going to work on the VIN 9 engines and I would also like to know what possible negative impact we might see as far as engine wear and long term reliability.

Will this be a situation where we send you our PCM and it get returned and they send it back? How will this go down?

03-16-07, 07:30 PM
I can believe 40hp on the supercharged engines. There was a "Horsepower" episode where they added ONE degree timing to a LS1 camaro running 8psi, and made an extra 40hp. With no additional mods, and a "premium only" sticker, expect about 20hp on a NA 4.6. Maybe.

40hp might be possible on the VVT engines

Hey guys, I'm posting these pictures for Jay... here how to locate your computer and service number:

In the first photo, it locates the computer.
2nd: The yellow circles show where the computer is held in. You just open those latches to see the Service #
3rd: Circled in red is the service number... Good Luck guys!

Thank you. I just don't see how Westers can say 25 hp on the 93-95 Northstar and 40 hp on the 96 & up. Same engine in 95 less the MAF on OBD II cars. I agree with you, 20 hp. Fastchip told me 12 to 15 hp for my chip. It feels about right, a noticeable increase in power and the speed limiter is removed. And all for only $159 plus shipping. Sure beats Westers price of $395 for their chip. I don't need to spend an extra $236 for "5 to 10 more hp", maybe?? over the Fastchip.

There's only one problem. Your the only one with the chip and probably will be for a long time.

I can believe 40hp on the supercharged engines....With no additional mods, and a "premium only" sticker, expect about 20hp on a NA 4.6. Maybe.

That's what I'm thinking. If 40 hp was as simple as a "tune", Cadillac would have already done it. Through Cadillac being conservative with fuel trims in terms of engine durability at WOT and such, I would buy a 15 hp increase. And as we know, superchargers and VVT add a completely other dimension to the possibilities of performance chips, over what you can get simply by tweaking fuel and spark mapping.

But, as skeptical as I am, I'll look forward to seeing results from what they can get, and I'm glad that someone has finally "cracked the code" so to speak on getting these OBD-II computers retuned. They just won't be doing it with my car. :thehand:

Hi all.

I've been off the board for a long time. (kinda doing my own thing in uncharted waters).

When I first put in the piggyback computer before it was turbo charged we took it to the dyno and played with the AFR. The computer was real time so we didn't have to reflash and wait for results. We went from very rich to very lean with virtually no change in HP. I emailed our old friend from GM and asked why. The combustion chamber on the N* is so efficient that a wide range of AFR will not affect its power output. The only way to gain more power is to get more air in and more air out. Meaning a cold air intake along with an open exhaust or going the route of super or turbo charged. I just can't see how this guy is going to gain 45hp unless he is messing with the timing and that can get dangerous if running lean. Changing shift points is not going to change HP.

I am not saying I am "the expert" but I have been messing with this stuff for the last 5 years and have tried it all with proven track and dyno results and I'm telling you the only way to get more hp is to do what I said above. Sorry but adding more than 20hp with intake and exhaust for a 4.6N* will take a lot of time and money.

Been there and still doing that.

CadillacSTS42005
03-17-07, 12:49 PM
Mark undoubtly you are the GOD about this
however even if it doesnt net us the 45 hp
it will allow us to use the stock computer to add a s/c, turbo, new heads, cams, pistions, remove the speed limiter on Y cars WHATEVER without having to go the very difficult and expensive route of the piggyback way
ya know what i mean?
i plan on building a set of custom headers this summer at my shop, i already have cat back done fully and i think it sounds alot more "muscle" than the corsa which is more refined
bGuXoroykgU&mode=related&search=
do i believe it will net 40 hp? on a stock car no, with an exhaust and intake maybe in total with mods youll gain about 20-30 hp.

Having said this I will take this as ROCK SOLID evidence that an aftermarket MAF will and can do nothing to increase HP. The only thing a MAF can do is alter the AFR and if we've tested that theory to this extent then I would say it's safe to assume that ANY MAF will do nothing at all period. Except maybe use more fuel.

I agree, Fastchips told me they changed timing & fuel curves moderatly, and the hp gain is 12 to 15 hp. That sounds more reasonable then 45 hp. Fastchips doesn't alter the shift points, which isn't needed. Vin Y engines peak at 5600 rpm, and mine shift's at 5900 rpm, which is right where it should be. 200 to 300 rpm past the hp peak.

Unless you have the ability to change the AFR yourself like with the piggyback it won't do any good because there is no "universal "program for fuel if you are going the route of s/c or turbo.
You can't just get a reflash and expect it to work in all cases. It is good for a stock setup, but that is about all.

Secondly if all you are are going to net is 20-30hp why spend the extra money when adding an open exhaust and intake will do the same thing? Already been proven with dyno by Corsa to add 20hp.

alot of aggrivation yes, but probably not as much as trying to piggy back it
plus i want them to be able to hack it so when i turn on the t/c ill keep 1st gear that would be GREAT!!!

Just want to throw this out there..

I'm not interested because based on what I've datalogged, there really isn't much to gain in the upper rpms from a tune. Mine's already pushing 31 degrees of timing and the tranny shift points / firmness adapt to the power you make.

You can add timing and pull a little fuel to make the burn a bit better... but $400 dollars worth? I guess if that's what you want to do then do it. I hope this GP works out for you guys if that's what you want to do.

IMO freeing up the exhaust, adding nitrous (safely ramped up), and running a matching fuel octane would easily put most any FWD N* into the 13s.

Pushing one harder than this is only going to make things start to fail.

Very interesting! Goes to show that blanket thoughts or statements are inadequate.

My 01eldo ETC hits 30-31 timing on 87, 93, 94, and even 98 octane fuel, summer heat or on 40 degree days. The shifts are at 5800 in drive (or if the shifter is left in 2nd as is popular here) When I spray for the first time in a while the shifts will flare up higher and the firmness is a bit soft. But after a good 2-3 WOT blasts the shifts will come down and the firmness will increase.

The only time I really see over 6000rpm consistantly is when it shifts while spraying a 100shot. Which I hardly ever do. I keep it down to the 35-to-50 range so I don't have to run above 94octane fuel. (At the track only is where I'l run the expensive fuel and spray 70 or 100shots)

Somethings not right with your PCM program. Vin 9 engines peak at 6000 rpm and should shift at least 200 to 300 past that. every one I've driven shifts at 6300 to 6500 rpm. Yours is shifting to early. By contrast, my vin Y Eldo peaks at 5600 and shifts at 5900 rpm. Time for a reflash.

wydopnthrtl
03-19-07, 12:26 PM
That is possible. I replaced the crank sensors. It also hunts at idle. Not much but it's annoying to me. Looking at it.. the timing is swinging back and forth at the exact same occilation as the rpms.

I've read on here about some having to do this after changing the sensors. Do you think I need this? What other things will a re-flash do? And I suppose a dealership has to do this? How much money?

Rich

clarkz71
03-19-07, 12:32 PM
A reflash should only put in the correct parameters in the PCM. Nothing should change but the shift point rpm. Check with your local dealer, there might be an updated new calibration.

weister,

you need to remove your air filter elbow, top of the air box, air filter, lower part of the air box, there's a little L shaped bracket w/5 socket head screws (at least there is on my 98 ETC) that needs to be removed, remove the plastic cover in front of the fuse box over the wheel arch, pull up on the PCM box, undo the two metal clips to open the plastic housing, pull the PCM up, flip it over, service number clearly labeled.

In my FSM which is for Eldorado and Deville, the Deville's shows the PCM box sitting in the same place as for the Eldorado down under the air box, follow instructions above, you can get it out in about 15-20 min...

I talked to Lyndon today. He would like to get some cars in there to put on the dyno and work on tuning. He'd like to start with '96 and go from there. Westers is located in Alberta Canada. So... who can leave their car for awhile? :)

Tom

as i told them id be more than willing to but id need an idea of HOW long theyd need the car for ya know?

I'll take a look at my PCM tomorrow and grab the number off of it. I've got my VIN memorized (don't ask, I've needed it so many times), so as soon as I get the PCM serial number I'll post it up. If it's going to me extremely expensive (i.e. $500+) I'll most likely not purchase it though. Plenty of other more important things I could spend that money on. I think $300 or so would probably be the maximum I would be willing to part with. Considering I've still got around $5000 in tools to pay off right now for work, plus brakes on my car I need to do, I can't afford to be spending large sums of money on trivial things such as a PCM tune. I think I speak for most here when I say...I would love to get rid of my speed limiter, and get a little more power....but I don't wanna pay out the ass for it.


edit: Also....how many people who are actually interested live anywhere near Alberta? They say they want cars to work with, but does anyone here who interested actually live up in that area? If not, then it's kind pointless if they can't get any cars to work with. Just a thought.

according to what ive herd, it will cost in upwards of 300 close to 400, however if we provide cars for the dynoing and continue to help with this it will keep the costs down...

The time that Westers will need the car will depend on how things go with the tuning and what else is going on up there. It would be longer than a few days. I'd plan on at least a week or two.

#12562481 considering my car is a 96 I didn't expect to see the same #16214848 which is the same # as danbuc's 98 and weister42's 98 but as you can see there are 5 service # so I'm not sure whether others should take theirs apart or not. If you check your post #110 everyone's # seems to be very similar. It might be a good question to ask because I'm sure you don't have 25 yet because some aren't looking forward to taking it apart, haven't made the time to do it, or are just lazy taking their time.

You can really only trust a G-tech time if it's corroborated by something else -- like a drag race, a track time, a dyno pull, etc. It was fairly accurate with my 0-60 time, but I didn't measure HP or 1/4 mile time with it, so I can't vouch for that.

I had spoken to a Roy Morse at a shop that bores out TB's for Sevilles, he says they can only bore out my TB 3 mm and pointed me to Westers for a computer reprogram, as the TB bore might cause computer problems. Here is the email he sent me:

Hi Kenneth,
Thanks for your inquiry. We can modify your throttle body. Cost is $217 + $8.95 handling. We usually enlarge the bore by about 3mm. This is a significant increase in airflow. You must be prepared to re-program the ECU if it doesn't accept the added airflow. Hope to hear from you, RVM

If anyone knows of a less expensive location or a better bore, please let me know. He also stated that my 2002 Seville STS does not need spacer for the new, wider throttle body.

i have been in contact with RVM as well, and they will bore it out as far as the core allows, which is 79-80mm depending on core...average starting TB size is 74-76mm or thereabouts, only pointing to an average of about a 3mm or so gain which is probably why he stated a 3mm increase in his email. The price to do mine INCLUDING spacer was the same price as yours and same S&H quote. you do have the spacer on a 2000+, it's just an even bigger PITA to get off the motor...and no...you WILL NOT need a PCM calibration simply for a "80mm" TB...it will still provide about 7hp/10ftlbs as verified by eldorado1's testing and others that purchased his units while in production

Oh, no kidding...a 3" exhaust with opened up intake and no cat WILL reduce your backpressure and low end torque. If you have no cat, and didn't make a provision to fool the downstream oxygen sensor, that's probably what the MIL is on for (because it's not seeing the reduction in oxygen that it expects to see). I would start by putting the cat back on. 3" exhaust isn't OVERLY big for these cars, but still...opening up the exhaust a lot like that will have an effect on your powerband. This is well-documented with intake mods and the Corsa exhaust. The cost for higher RPM horsepower is often lower RPM torque.

Oh, no kidding...a 3" exhaust with opened up intake and no cat WILL reduce your backpressure and low end torque.

Backpressure WILL reduce your torque. Everywhere.

http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=355


Few tests have been done that clearly show the effect of changing back pressure. Most muffler and exhaust comparison tests change more than one parameter simultaneously, making the identification of exhaust back pressure as a culprit difficult.

However, Wollongong (Australia) mechanic Kevin Davis has done extensive testing of varying back-pressure on a number of performance (http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=355#) engines.

These range from turbocharged Subaru Liberty (http://www.team-integra.net/sections/articles/showArticle.asp?ArticleID=355#) (Legacy) RS flat fours to full-house traditional pushrod V8s. In not one case has he found any improvement in any engine performance parameter with increased exhaust back pressure.

The tests came about because Kevin has developed a patented
variable-flow exhaust that uses a butterfly within the exhaust pipe. He initially expected to use the system to cause some back pressure at low loads 'to help torque.'

However, he soon changed his mind when any increase in back pressure proved to decrease torque on a properly tuned engine. What increasing the back pressure does do is dramatically quieten the exhaust.

One of the engine dyno tests carried out by Kevin was on a modified 351 4V Cleveland V8. Following the extractors he fitted a huge exhaust that gave a measured zero back pressure. Torque peaked at 573Nm (423 ft-lbs) at 4700 rpm, with power a rousing 329 kW (441 hp) at 6300 rpm. He then dialed-in 1.5 psi (10.4 kpa) back pressure.

As you'll see later, very few exhausts are capable of delivering such a low back pressure on a road car. Even with this small amount of back pressure, peak torque dropped by 4 per cent and peak power by 5 per cent. He then changed the exhaust to give 2.5 psi back pressure. Torque and power decreased again, both dropping by 7 per cent over having zero back pressure.

So much for that idea..... I bet he was thinking he'd be rich by marketing that variable exhaust backpressure valve....

jadcock
05-06-07, 07:42 AM
I wonder how those rice rockets put 4" exhuasts on their car (reducing backpressure) and lose any low end they hoped to have. Reducing backpressure by a lot often slows the car down, in the low end. We've had this discussion often before. Increasing high RPM horsepower usually means losing low RPM torque. It's been reported with the Corsa systems repeatedly here.

That snippet doesn't prove anything. It's saying he lost peak torque with increased backpressure. Yes, this is true. It doesn't say anything about driveability or torque down low, where it's not peak. It just means that as he increased backpressure, he wasn't able to get quiet as much out of the engine, at peak, on a dyno. This we already know.

I'm not sure how his variable-flow exhaust valve operates, but Z06 C6 Corvettes use the very same variable exhaust design, likely to effect exactly what we're talking about here.

- Heated Oxygen Sensor (HO2S) Replacement Bank 1 Sensor 1 or Heated Oxygen Sensor (HO2S) Replacement Bank 2 Sensor 1 in Engine Controls - 4.8L, 5.3L, and 6.0L.

- Heated Oxygen Sensor (HO2S) Replacement Bank 1 Sensor 1 or Heated Oxygen Sensor (HO2S) Replacement Bank 2 Sensor 1 in Engine Controls - 8.1L.

Install the J 35314-A in place of the HO2S sensor.
Start the engine.
Increase and monitor the engine speed at 2000 RPM.
Observe the exhaust system back pressure reading on the gage.
Does the reading exceed the specified value?



VALUE = 6.0L - 3.4 kPa (0.5 psi)
:yup: yup .5 PSI

Increasing high RPM horsepower usually means losing low RPM torque. It's been reported with the Corsa systems repeatedly here.

That snippet doesn't prove anything. It's saying he lost peak torque with increased backpressure. Yes, this is true. It doesn't say anything about driveability or torque down low, where it's not peak. It just means that as he increased backpressure, he wasn't able to get quiet as much out of the engine, at peak, on a dyno. This we already know.

I'm not sure how his variable-flow exhaust valve operates, but Z06 C6 Corvettes use the very same variable exhaust design, likely to effect exactly what we're talking about here.

Anyone have anything other than a butt dyno of the Corsa system exhaust? No?

Corvettes use a WOT cut out valve. The point of that is to have both a quiet exhaust at idle/cruising around town, and performance, by eliminating most of the exhaust [backpressure] at WOT.

In fact, people who have bypassed the WOT valves have noticed low torque GAINS:

http://forums.corvetteforum.com/showthread.php?t=1670220&page=2


when the switch is on and the butterflys are open there is a performance increase that shows up in the low end torque significantly.
Plus the top end power is also up. So it is a win win situation.

The whole power curve goes up but the largest increase is below 3500 rpms.

AJ - 0.5PSI at 2000 rpm is a LOT different from 0.5PSI at 6500 rpm. The latter is not obtainable except with open headers. A "performance" exhaust will have <2psi across the whole power band.

1.5 PSI @ 2000 will cause a misfire. You can get a single cylinder Misfire and it is more common than the whole bank.

Exhaust Tail Pipe Flow Control System Description and Operation
The Exhaust Flow Control (EFC) System enhances engine performance. The system has 2 modes of operation:

Normal

Competition


Normal Mode
When the vehicle is stationary with the engine running the exhaust flow control module (EFCM) commands the vacuum solenoid On, which supplies engine vacuum to both exhaust flow control valves. This causes the valves to close, diverting exhaust flow through a baffled path inside the mufflers. As vehicle speed increases, throttle position reaches 25 percent or greater and engine speed reaches 3500 RPM, the EFCM commands the vacuum solenoid off. This causes the valves to open, diverting exhaust flow through an un-baffled path inside the mufflers, thus enhancing engine performance.


Competition Mode
When traction control is driver disabled, vehicle speed increases, throttle position reaches 25 percent or greater and engine speed reaches 3000 RPM, the EFCM commands the vacuum solenoid off. This causes the valves to open; diverting exhaust flow through an un-baffled path inside the mufflers more frequently and at lower engine speeds.

The system also delays exhaust valve activity during wide-open throttle acceleration to inhibit exhaust valve actuation when the accelerator pedal is released and reapplied while shifting gears.

The EFCM has the ability to detect electrical malfunctions within the system. Any electrical malfunction detected will cause the system to be disabled and increased exhaust audibility.

The system uses the engine control module (ECM), body control module (BCM), electronic brake control module (EBCM), EFCM, exhaust flow control valve vacuum solenoid, vacuum reservoir, vacuum lines, 2 exhaust flow control valves and the serial data circuit to perform the system functions.

Anyone have anything other than a butt dyno of the Corsa system exhaust? No?

Actually, I think so. Corsa includes a rather cryptic dyno graph on their website (for the FWD Seville exhaust):

http://www.corsaperformance.com/STSdyno.jpg

No matter what gear the car is in during that dyno (why show MPH instead of RPM?), you can see that the gains are minimal to non-existant at lower RPMs. In fact, you'll notice that SOME parts of the blue line, the Corsa line, actually fall slightly BELOW the red line, the stock line. You'll also notice that the blue line starts 10 MPH higher than the red line. Why? Is it because at below that speed, the blue line is significantly lower than the red line? I guess we'll never know. ;) ;) Looking at this chart, and combining with it the field reports of loss of low-end torque, I believe the picture becomes pretty clear.

Edit: in 3rd gear, 128 MPH is about 5800 RPM, with 3.71 final drive and 27.1" tall tires, so it appears that that's what they're working with. 60 MPH, where the Corsa exhaust dyno begins, is 2800 RPM. I'd really like to see what's going on below that...funny how that's left off...

I can't find any dynos on corsa's site... So here are some dynos from magnaflow's collection:

http://www.magnaflow.com/02product/dynos/16636.jpg

http://www.magnaflow.com/02product/dynos/16619.jpg
http://www.magnaflow.com/02product/dynos/15838.jpg

I tried to pick ones with lower starting RPMs to show as much of the curve as possible. I see nothing but gains across the powerband, except for the C6, which makes sense because the stock exhaust is probably pretty damn good. Is it possible Corsa, or whomever did the dyno, "eased into" the throttle? Take a look at the last dyno I posted.

Here is the page where the dynos are posted:

http://www.corsaperformance.com/devilleseville.htm

Here's an interesting quote from the Gibson exhaust website, and is consistent with my experience with exhaust and backpressure:

To reduce additional backpressure, the OEM exhaust tubing can be replaced with mandrel-bent tubing of the same size or one size up from the OEM. As a general rule, you can enlarge the pipe diameter of your OEM exhaust system by &#188; to &#189;-inch to increase your horsepower. However, any additional increase in pipe diameter is likely to decrease your performance; specifically, low-end torque. (Source: http://www.gibsonperformance.com/index.asp?p=power)

I guess I'll concede that reduced backpressure doesn't necessarily guarantee a reduction in low-end torque, but that is shown to be the case, in some situations.

This is gettin crazy, look all Im sayin is I think the exhaust if too free flowing for the stock pcm tune. I live in SOUTH Florida, its ALWAYS 90 degrees and VERY humid here, When it does, once in a blue moon, get into the 50's, the car with this set up, runs like a raped ape. The cold air causes the pcm to increase spark timing among other things, and the car goes nuts (5.9 0-60, and 14.2 1/4 mile) g-tech times. Same car, same g-tech , when its 90 degrees out (6.8 -60 and 14.97 in 1/4 mile)...point made.

I'd drop my car off in a heartbeat if I wasn't like 3000 miles away. The best part for those who do is that they'll wind up with a custom dyno tune.

I've used HP Tuners for years on my 99 GTP and 01 Suburban. I can scan the N* but not modify the tune. Both DHP and HP Tuners have been hacking GM OBDII computers for some time and both sell their software so people can do their own tunes. Both companies have expressed no interest in tuning N*'s <-----------

The combination of VIN and S# make up an OSID that the computer uses. If I flash my GTP with the stock Pontiac tune the OSID changes from the generic upgrade I got from Intense Racing.

To truly tune a car for max HP, the car has to be on a dyno with a wide band O2 sensor. Otherwise its a shot in the dark. Case-learns need to be performed as well. Additional mods (a cam) after a custom (or generic) tune will require another tune. As others have posted, a CAI and opened up exhaust go hand in hand with custom tuning.

The other things that having tuning software allows people to do is (and these may not all benefit a N*) is to raise shift points, modify the way traction control works (I had to edit it all out in my GTP), remove emissions codes (hi flow cats screw up O2 sensors), remove speed limiters. With all this stuff you can really screw your car up if you don't know what your doing - I thrashed a tranny by screwing with the torque converter settings (kept it locked during shifts).

Hey Bros where do I look on my 03 sts for the number you guys need for westers. I am dying for the chip too. Rolling around at 130 all day sucs. Seriously, I dont care how much the chip is, ill buy it right now. Ebay has the Corsa for a touch over 1k too. Should I get the Corsa or is the stock good enough?

As soon as you tell me where ill post my info for westers too.

06-12-07, 09:48 AM
Lyndon does not respond to emails. I have sent a half dozen to the company and the only thing I EVER received was "we will get back to you". That was IT! It there ANYONE that is working on the computer for the N* engine? I want to put a 80 MM throttle body on my 2002, but it seems that the water jacket will need to be honed out as well. Other members on this site have stated that putting a 80MM TB on the Seville will RUIN the low to mid end torque, the company that does the honing says it will INCREASE the low to mid end torque.

Does ANYONE have dyno results and/or experience with this upgrade? I have the Corsa exhauast on the car, going to buy the Jet Chip MAF sensor, but I don't want to start cutting holes in my intake system unless I know there will be an improvement. I even bought a SECOND TB for the car, so if it gets honed and ruins the low end, I can put the stock one back on the car. Question is, do I need to hone the Water Jacket as well to see any benefits?

DOES ANYONE KNOW????

msta293412
06-12-07, 02:39 PM
Good question about the throttle body. I have a 2001 sts, same set up as yours, Id like to know the answer to your question. I have a corsa spec exhaust as well, made by magnaflow... By the way, I have the JET chip MAF, and it does give a little extra HP. (not to mention I modded the airbox and intake runner)....Lyndon is definetly stalling, I actually spoke to the man in March of this year, and he said to me they would have it done by the end of April, You see how that went.....Hope this AJ thing is for real....

mikekilpatrick
06-13-07, 09:38 AM
How did you mod your intake box? I have seen several approaches to this on the website, but have been a bit weary to proceed with that mod. Did you gain alot of noise from the modification?

Mike

msta293412
06-13-07, 10:13 PM
Well, Ill try to make this short...but when you pull the shroud off above the headlights...take out the airbox and cut a hole directly behind the head light, theres even a hole in the metal, withch is open to the front grill...basically when your doin over 50 mph, its kinda like a ram air...I also removed the baffle under the airbox, witch was almost sealed off completely...now sucks air from behind fender well...Off course KNN drop in...left the box sealed, with extra weather strip, from hot under hood air....have the Jet Chip MAF, and bought a 4" elbo, from vibrant performance along with matching silicone....got rid of all that plastic container, rubber, crimpled whatever intake they had, witch did not flow properly.....and VOILA!....Oh yea...it is louder, but only at full throttle...performance gained was definetly noticed....throttle response was improved as well....
