Quick tune question-need answered ASAP This is a general question, but specifically I'm using a Predator on a 2000 TransAm.
I got the SES light for some problems. The car is still under warranty but before I bring it in, I want to restore the stock tune.
Will restoring a stock tune erase DTC codes??? I do not want this.
If so, does anyone know if a GM reflash of my PCM will brick my Predator? I've heard conflicting stories on this.
Thanks.

yes, the predator will reset the codes when you restore the original backup.
but if you really have an issue, the SES light and codes should pop back up again...

Thanks for the replies.
I just talked with Diablosport, and they told me it wouldn't reset the codes. Now I'm confused.
I've been having this intermittent shift problem, well it happend today. It's a code P0748 "PC Solenoid Electrical". It's a Type C code, which means it won't set the MIL. I also have 4 other codes that are showing up, others are O2, misfires, and lean condition. These throw the SES light. Problem is that the car is under warranty, and these fixes are free, but they have to see that a problem exists. I'm not worried about the other 4 codes showing up, it's that elusive P0748 that really has me
Oh well, just going to reset anyway and see if they go away.

Yep, reset them.
I got 3 of the 5 back right away, none of them set off the SES light. The random missfires code (P0300???) was the one that is probably setting it off, we'll see if that one pops back up.
I really wanted to take it to the dealer with that damn P0748 code, but I'll have to wait till that one pops up again.

it may take 2 or 3 driving cycles to get it to pop again... so it could be a couple days

Restoring the backup to the car will, as part of the flash process, will clear any codes.
By any chance, are you running an aftermarket MAF on this car? (actually, just saw MAF listed in your sig....what is it?)
It also says it is tuned by ECS.....whats the deal there?
If they have tuned the PCM in the past, and you are trying to tune over it withthe Predator, you will have problems...
Thanks

MAF is back to stock long ago, I should update signature.
ECS did a street tune on the car, and that's what's in there now. The only thing I've done with the predator is change the gear ratio and shift points and use it to pull codes.
The harsh shifting problem is something intermittant that has happend for a long time, before the ECS tune and before the Predator. Also, the SES light came on before the predator update, so I doubt that should affect anything.
I even posted this on the diablosport forums, where I wanted to use the Predator to just alter shift points and speedometer settings, on top of an aftermarket tune. For that goal, it has worked fantastic.
