If I can see the difference between the Y and 9 Then why can't I go Further?

Valium.

You said "some", which means finding a german car with a W rated factory tire (or whatever) on ebay and borrowing the VIN.

There is more to it than just finding the differences between the calibrations. You need to find out what those differences are. Say you have a block of hex. It's obviously a table. But what table is it? Fuel? Spark? Transmission upshift? Downshift? maybe something completely worthless like EGR % vs RPM.

Are you going to start changing values to see what it does?

I'm curious now.

[AJxtcman]

or I could just give you the VIN's

[AJxtcman]

That is for the ones that got my email.

If you got it do you believe me know?

[codewize]

Hey I didn't get it What gives?

[AJxtcman]

This looks better

I would still like details on what the pcm will have upgraded when I get it back. Again....a/f ratio change?, spark timing advance?, torgue curves? line pressure?, speed limit delete? How will it work with my mods? etc. This still hasnt been answered clearly....OR......am I getting a stock pcm that is NOW tuneable? Please in laemens terms.....Thankyou all......

I will make a very stock unaltered calibration for you. It will have all OEM specs in it. Since line pressure should stay close to you application or it will adapt it right out and set a DTC I will leave it alone. Since the timing is Adaptive also (northstar has it) I should leave it alone or the adaptive timing will think it is running on 86 octane and set a DTC for Knock sensor performance I better not touch it either. I don't have a list of mods done so I better leave that alone also. I am not sure of your tires you may have H rated tires and I would hate to have one blow out because you went over the speed of the rating for your tires. .
.
.
I say within a year I will have a program to sell that you will be able to make your adjustments with a laptop..
.
.
Ok how about I set your car up with multiple parst from OEM calibrations that I can EDIT.
How about A/F and trans PCS for a 50 foot limo
How about Speed limiter of a QWD tire
How about timing of the quickest ramp that I have.
.
.
I am still working with the Program and learning it. .
.
BTW I can call GM and get a speacial calibration called a VCI #. If you change tire size you can get a VCI #. If you change CAMS you need a VCI #.
.
If I can call them and tell them I did cam swap XXXXX then they give me a VCI # within a minute. I need to give them a VIN and other info, BUT THEY HAVE THE SOFTWARE TO SET IT UP AND THEN I DOWN LOAD IT INTO THE CAR.
.
.
Who is to say I don't have some software to that!!!!!

Do you all remember that 20 second 0 to 100 SLS that I posted the snapshot from. Then I had a no start with the new PCM. I have it now with my program in it. I will try to snap shot it. Traffic is bad right now, But I am going for it.
.
.
i will post it soon

[AJxtcman]

This is the same 02 SLS. I ran from a dead stop to only 92 mph Because of traffic. It ran 14.978 from 0 to 92. I have the other snap shot at home on my PC so I can not find the time at 92 MPH and show how much it picked up. I will later tonight.

[codewize]

Now! I'm even more lost that I was before. Are there encrypted messages here?

I can help.
.
Send me a pcm and you will love it.
.
That is the bottom line.
.
It will not be a OEM, Factory, or GM calibration that any car left the factory with.

[AlBundy]

The 96 - 99 pcm are still on the burner right?

[ejguillot]

I'm also interested in a reprogrammed PCM, and am watching this discussion with great interest. What I would be looking for:

Speed limiter delete
Corrected shift points (My car shifts at 6300 and fuel cut off is at 6500, shouldn't it be 6500/6700 for a 2000 STS, 8/99 build date, VIN # 1G6KY5492YU144325)
Eliminate any torque management, also maximum shift speed/line pressure when shifter is at 2 or 1
Most aggressive factory fuel/timimg curves available (My N* is tuned for regular, I would accept having to run midgrade/premium)

Any particular PCM I would need to send you, and is used OK (can I pick one up from eBay or a junkyard?)

I started with 99 vin Y in a FIERO.
I have a few things that I can do.
I can only do a few more things to 2000+, but that is what the call has been for. I have been spending my time on that program.
If you get me a PCM I will work it over and then send it back. If you are not 100% satisfied I will try again if you would like.
