  • VSS correction for Isuzu swap?

    I recently swapped in 93 Isuzu 5spd to my 92 Beretta, I'm using Getrag based .bin now, and speedo shows that i'm making like 70-100MPH on idle, and driving at city speed will bumb the speed limiter soon (256MPH), so i have to drive VSS unplugged.

    Help anyone? I got Moates APU-1 and all the software and else i need for the fix, anyone know the right valueselse?
