Nissan 370Z Forum - View Single Post - LF: Older Uprev Rom file for 370Z Nismo or G37 IPL

Bump**

If no one has an older ROM... can anyone chime in on the MAF/MAP Throttle position correlation code that comes up when you go FI or use a larger MAF housing? AFs have been tuned and I have tried altering the MAF table as well as going all throttle relearn procedures to try and get around the code but it still keeps putting me into limp mode on long highway commutes.

FYI: tuning was initially done by setting fuel comp table to 100 across the board and adjusting k value to get initial stable AF numbers. Fine tuning was then done with the fuel comp table.

I know the first answer is going to be go ecutek... but I'd rather not waste the money spent on the Uprev tuner package and the ARC add on...
