Hey all,
I recently swapped my CMR tune to HP tuners and after doing so am getting a "P0731 - Gear 1 Incorrect Ratio" CEL which is throwing to car into Limp Mode. I will admit that I didn't realize I had to jump into the VCM scanner to adjust the Tire Size and Gear Ratio initially but after making those appropriate changes my car still throws the same CEL.
Has anyone ran into a similar issue? I'm kind of at a loss here. Any way that HP Tuners didn't fully read the CMR Tune? Could this have something to do with NAG1s needing to be "re-initialized"?
Any ideas would be greatly appreciated,
Bruggy
