There are a number of part numbers for QP TCUs. To the best of my knowledge, there are three "groups" of compatibility, maybe 4 but there are like 8 or 9 different part numbers. Being a late model Sport GT, you'll need one from a late model Sport GT. There were many adjustments made in that MY that controlled shifting.UPDATE:
Sadly, the car is in still the garage after my last message ...
The garage quoted almost USD 2,000 to get a TCU with the same software number. Part# 2306441. Software version CFC301F.64
I found a TCU from a Quattroporte locally for USD400 approx but not a SportGT version. Almost the same Software # (CFC301F.63), but different part# (219347)
We tried it with a brand new F1 pump as well... The car started... gear is shifting... car is driving.... but it is not driving properly. High RPM with slow speed. They said it is because my car is SportGT and the TCU that I got is not the same.
Is it really not possible to reprogram a TCU to the same software version?
Any leads where I can get a cheaper TCU with part# 219347 with Software version CFC301F.64 ?
