They told you that?!? That's strange. Unless something has changed in the software, ProCal3 generates a backup file that is what you use to revert back to stock. However, I did this a few years back, and I've never attempted to revert back to stock, myself. But I know users on this forum who have done so successfully.I was told by Ford Performance that there’s no longer a way to revert back to your stock tune after installing the ford performance tune using the procal 3. Has anyone else had this issue?
Again, I haven't opened up that software in a few years, so I couldn't tell you for certain, but I do know that I have a backup of the file it created. Sending out the bat signal for @slojas who I know did use it to revert back to stock from time to time...but its also been a few years for him, as he's moved on to a GT.They stated “Unfortunately it does not have a return to stock calibration function. If you wish to return the car back to a stock calibration, you can take your vehicle to your local Ford Dealer and they can flash the PCM back to stock with the ‘As Built’ calibration for your car.” Even though My computer was used to install the tune.
I may be wrong (on Mustangs), but you can't just get a PCM off another exact model stock car and plug it into your car. It's not a DIY "plug-n-play" repair.I figure if I truly need to go to stock, I’m going to buy an pcm off a wrecked 17 eb premium that’ has stock tune and toss on my car
So you reprogrammed the ECU following the instructions using the backup file and it did not put the stock tune that is in the file back on the car?Thank you for your reply.
I did check that the accessport is the correct part and updated. I did see and follow their instructions and saw the same thing you did. But unfortunately their instructions didn’t match up and there was no restore option. Guess I will have to get ford to restore the stock file.
That's my understanding also.So you reprogrammed the ECU following the instructions using the backup file and it did not put the stock tune that is in the file back on the car?
My interpretation of how it works is you get the tune file from FP and the tuning process makes a new file (backup) with the stock tune. You then tune the car again using the backup file with the stock tune. It will then make a backup file with the FP tune.
There is no need for a restore option with that scheme.

Its been tried, the guy had same problem as me, he was flashed to as built from factory at dealer, and didnt fully remove the ford perf procal settings. so nope, you need that file now. things have changed since originally done, the new tune has new files and as built file just doesn't get them all. im leaving mine FP as well. not messing with it. happy with it honestly to not care.
