I've a question re upgrading a transmission control unit (NCR) in a 2006 or a 2007 QP-V... where the car is NOT a Sport GT. Let me explain further...
In North America all QP-V's after VIN number 21925 had SOFAST3+ associated with their DuoSelect transaxles... and CFC301F.62 NCR's - except for the 2007 Sport GT models which had CFC301F.64 NCR's. This latter-cited NCR gave the car superior DuoSelect performance, with 35% faster shifts (under some conditions) and by the accounts of many folks is the one to get. I'm told that to switch a car that had the former F.62 NCR over to the F.64 version a "Proxi Alignment" would be necessary. Fine, this can be done. However, are any other specific software files necessary to have, say, from Maserati HQ, in order to effect this change? In the following case of a NIT upgrade, the "files from HQ" issue was a problem:
