Car has SAI code. Would like to tune out SAI system (and maybe if possible free up some performance as well).
VIN (if that helps): WAUDL74F86N031344
I have tried to read the ECU using:
- Nefmoto pro
- MPPS (using all 4.2l listings, all 7.1.1 listings, S4, A6, Allroad)
I cannot read the ECU.
a) what can I try to read (and ultimately flash) the ECU
b) is there a tune already out there for the car that has SAI deleted (wouldn't mind rear O2) and some performance enhancement done (really secondary at this time)?
Did you get anywhere with this? Curious on what you learned...
