01 DTS would be great to show you

I will pick up a PCM set up a calibration and run a car with it first to make sure it is good. Then I will reprogram it again and reset the theft learn and mail it to you.
I have one program for a 99 Seville that I can not start the car. All 99 Seville's run PK3 correct? For some stupid reason it will not recognize it. It come up with invalid password. I have tried everything to get it started.
I will make sure this will not happen to you.

I am talking no converters, No speed limit, increased HP and not from no converter.

[AJxtcman]

Do you have any IDEA why Westers want all the VINs?
I do!

This is my current Northstar 99 VIN Y Snapshots with a Tech 2
First picture is at the start
The second is at 0 MPH and .925 seconds
The third is at 100 MPH 10.577, but then you take out the .925 seconds and you get 9.652 second at 100 MPH
The fourth is at 120 MPH 14.690 - .925 = 13.765 second 0 to 120 MPH. It was still going.
The fourth was another run 0 to 102 11.102 second but I donot have the first frame so it was probably faster.
The rest is G Tech and the Tech 2

TANSTAAFL......There ain't no such thing as a free lunch...........this thread should prove interesting, for a number of reasons........Such as, If your programming runs in "PASS" all the time, is the PCM still able to control fuel rate, timing, F/A mixture, EGR (screw with EGR and you get impressive detonation), cat control, etc.? And what N* vehicle did a 9.6-0/100? Man, I hope you're on the right track.......you'll be the next Vic Edelbrock/Joe Mondello.

VIN Y.....The 275 hp N*?

No convertors? Explain how I pass a under vehicle mirror test PRIOR to OBD II plug-in.....

I left on out

The last 10 times I have been to the IM240 emissions test station they plugged in to the DLC and then checked the gas cap. I have heard of a mirror test, but I have never seen it done.

Everthing I have listed is all from GM calibrations. That is the easy part. The hard part is figuring out the definition files that are different between the two and then use them to rebuild a CALIBRATION.

So tell us why Westers wants the VIN's. I have a guess. If you're willing to let me demo this thing for free I'm game but I also question the ability for the PCM to correctly control the drive-train after the mod.

Are you loading the Abu Dhabi calibration? With manual spark advance override?

Have you heard of TIS?
that would be GM's TIS that is gone and disbanded?

I have no clue tell me more.

If you're running 13.5s in an otherwise stock car, there are HUGE compromises you're making with your calibrations. GM runs the cars rich at WOT to reduce the possibility of melting a piston, for example. How are your calibrations at WOT?

There are still obviously a lot of unanswered questions here. And I know you're apparently not far enough along to get your equipment on a dynamometer. But that's what folks like us will want to see. 13.5 seconds on an otherwise stock car is 100+ hp...just with PCM calibrations. Why didn't GM runs these calibrations? The answer is likely due to longevity...something a hot rodder may not necessarily be interested in, granted.

The point is, there are a lot of things that GM accounted for when doing their tuning. It sounds like you had snow on the road...meaning you were testing in the dead of winter (great for performance). I hope your calibrations will work equally well for someone living in Phoenix during the summer as they will for someone in Ontario in the winter.

And 01DTS's question remains unanswered. If your tuning puts the OBD-II system into a constant state of "pass" or "ready", how will the system find and report a fault in, say, the EGR valve, if there is one?

i have been tuning GM for 4 years if you need any help with beta testing or dyno tuning or anything i could try to help in any way to get this to work

dyno tuning wont cost anything i will suply the dyno

jadcock; It's actually my car we're talking about.

TIS, Hmm interesting. What can we learn from that? how does the public ensure they have the latest programming?

It was much better when we had carburetors and distributors LOL
