Hey everyone, I have a '96 GT Convertible and recently changed the 3.08 gears to 3.73. I just picked up a SCT X4 7015 tuner so that I could correct the rear axle ratio. The issue here is that I plugged in the SCT and it detected it was a Mustang. I selected the pre-programmed option and then the 4.6L option. It brought up a few things I could change (interesting that tire size and axle ratio were not in the list of options - my reason for buying this). Anyhow, when I tried to save the tune it gave me an error, 110BE - Unlock PCM Failed. Odd, the car is stock. In doing some research online there seemed to be indication that even a change by Ford can lock the PCM. I recalled seeing something stuck to the top of the radiator shroud and sure enough it is a sticker labeled "FORD AUTHORIZED MODIFICATION". Below that the writing is pretty worn off but I can make out "Reprogrammed PCM". There are a couple of lines below it, the first only has a handful of letters and is difficult to make out. Looks like: H*PRZ. The line below that has more letters, here's what I can make out:
FU2F ***A850-GE.
The asterisks denote a character that I can't make out and the ones I can could be wrong but those are my best guess. Shows the date performed as 10/20/97.
Does anyone know if there was a recall or TSB back in '97 for the '96 that would have resulted in this PCM modification?
The car was originally my dad's and he owned it since new and I inherited it when he passed. I will call the Ford dealer that was local to him but not sure if they will have records from 23 years ago. I'm curious what this modification was.
I'll also be reaching out to SCT to see if they have any knowledge of this and to confirm whether or not their X4 device supports changing of the gear ratios for the 1996 Mustang GT which was the entire reason I purchased this tuner.
