PAGING JULIO/CARTEK
One thing I can think of that is a long shot is check the build date on your car (in the door), maybe GM screwed up? especially if its a 2000 built early in 99.

I am curious if it is in fact a '99 program now, and if so, then why? Is there was a certain reason that my programming was switched from '00 to a '99 for tuning purposes?
Now you know to stick with a tuner who is looking out for your best interests. Sean <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
I CAN'T WAIT to see what gremlins we find in my programming.

To answer your questions, I was having issues with the car (popping, rolling idle, backfiring) so we decided to go back into the car and retune. I left Cartek dynoing in 403/376 SAE, first pull of the day (yesterday) at JD's relatively matched those numbers. After a few hours on JD's dyno, I was tuned in at 415/392 SAE... I am pulling over my previous torque peak number for over 2800 rpm's. There is a substantial difference all throughout the powerband for both power and torque. The car is a completely different animal now
So it is what it is, regardless of the situation I am happy with these final results.
What I want to know though, the only thing that I can't figure out, is why I have a '99 program in my car.

<strong>I'm wondering why I have a '99 program in my pcm now? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Erin, LS1-Edit can't change the vin in the ECM, I edit the original file that is in the car. The first thing I do is to read the ECM with Autotap and determine if there are any codes, then I read the existing program that is in your car, edit it with LS1-edit then write the program back to the car.
If your ECM vin number doesn't mach your car's vin number then it was already changed when you came in for tuning or some one reflashed your ECM after I tuned it and that must be done through a Tech-2 or by trying to hack the ECM.
BTW, I never got any email or phone call fron you.

What Erin is trying to say is that Dennis brought it to both of our attention when he looked at the PCM addy info, not on edit, that her VIN number was not on line #4020 as per a 2000 vehicle, it was on data line #6020, which is a Vin data line for 1999. Now, we will confirm both VIN numbers tommorow because I have no idea how her Edit advertised 2000 VIN # can function properly when all the data is referencing to a 1999 data line #6020. We are looking at the raw Binary/Hex data address for every function in the computer program that nobody else can see, and can't be seen with Edit. All we know is that she went in with a 2000 VIN location and came out with a 1999 location? Any insight to that would be helpfull? There is no harm in what has happened because the old file was saved and removed from her PCM and started fresh, we just couldn't undersatnd how the data recognition "hand shake" was possible with this discrepency. I guess it was more of a question for us more than it was a problem.

And like I said in this thread, my email bounced back, I had a cartek.net email for you. I didn't call because your shop isn't open Sundays and I was anxious for an answer.
Maybe it was done when you guys tried to swap files by desoldering chips on the board or something. What year is Tomcat's? 99 or 2000?

I am an excellent chip welder, J/K I don't think thats possible, unless I tilted the chip to one side when it was removed and the data slid around inside the chip. Who knows, I don't really care, it's just that Erin had a problem with that news. Tom Cat is a 2000 according to the dash plate VIN.
