For you guys that have programmers i have some software and hardware numbers....
hey guys , as some of you know i just bought a 05 GTO and have been experiencing some problems with it when i turn the A/c on , the idle surges and it makes it run super rich. My dad brought home the Tech 2 and we found that the engine load shows a minimum of 20% all the time , cooling fans are at 99% all the time also. When i bought it from the second owner he said it was programmed not sure with what or knew nothing about it. My dad and i pulled some Hardware and Software number of the computer , and i was thinking some one that has a 05 with a programmer , superchip , diablo , etc can maybe check theres and see if the number are similar? so here it is
Hardware number 12596003
Software number 12596734
92179530
12596763
92179530
92179522
92179528
92179523
92179532
92179526
So i guess if i cant find the brand of programmer , i will have to clear the aftermarket program off and load the stock GM one. I also have another guestion for your guys that have your gto's programmed is it possible to turn Cat. sensors off or something , cause i have full exhaust no cats and no check engine light???
I would appreciate any help i could get , i'm stuck
The O2 sensors can be turned off by going to the engine diagnostic table. The codes which should be set to 3 are P0420 and P0430. You cannot reload the factory GM tune without the stock o2 sensors. I would find a Corvette speed shop in your area and have them dyno tune your car with LS2 edit.
Aaron – Sounds like this is driving you a little crazy…
Personally, I have never been fan of hand held tuner thing-a-majigs. I think the best approach is to find a good LS1 / LS2 Tuner. Around 20 minutes on the Dyno. will get your GTO tuned “properly” Expect to pay between $75 & $100+ for a tune. Worth every penny IMO, not only for your AC issue, but optimum performance as well. Also, you will get the Dyno. sheet showing you RWHP & torque.
Some folks will not share my opinion, but it’s the route I would go…
okay , the 02 sensors are still in the mid pipe? So what you are trying to say is that once i reload the stock map to the computer , the codes for my cats will come up? And none of the programmers have the capability to change that? Is it normal for it to have 20% engine load at a stop , with the trans in neutral?
Many ways; yellow pages, web, or post a thread here on this forum. I would also look back through old engine threads to see what has been posted in the past. I think you will find there are more than one to pick from...

I live in Elburn, IL zip 60119 , and what is a rough idea on a dyno tune, just so i have a ball park?
These guys are about 40 miles from you, call them and let them know what you have. A dyno tune will optimize your program and allow the maximum power to match your mods.
