It would go back to the pre-fix software. Would obviously fix the missing torque that has been neutered in the fixed version.
I'm trying to decide which is best:
1)Keep the fixed software revision number. So at first glance a dealer would think it has been fixed. This which would be detectable to a dealership if they looked into it hard enough though because it would change the calibration number.
2)Keep the pre-fix software number. So a dealership would see it as a stock pre-fixed ECU and this would prevent your car getting TD1 flagged as possibly being tuned and voiding your warranty.
I think #2, but want more opinions, or I could do either as an option.
Either way should you have to take say a #2 ecu into the dealer for warranty work, and they would reflash it back to fixed version I would only charge for shipping to anyone that has already purchased this from me.
Now the caveat the ecu's are a pain to get out (see PDF and security bolts).
Unless you can be without your car for a few days I would have to first send you a loaner. You install the loaner ECU, and send me your ECU back for programming. I then send you your original ECU back. You install your original ECU back in, and then probably I will have you ship it directly to the next person in line.
This is a little different than what we are doing with the TCM's obviously.
This is due to the immobilizer that is in the ECU's that is tied to your car.
