Since I got the MPVI2 and I noticed it says it supports TJs I thought I would poke around and see what it could do. I noticed under speedo->Calibration is has this Factor Max and Factor Min. Does anyone know how those actually work if I wanted to recalibrate for gears or tires?
Good question? If you figure it out please let us know. I have a 97 tj but geared correctly and have the right speedo gear so mine is dead nuts on.
I'm scratching my head with this as well. My '01 TJ has the same Min/Max in computer. I'm running 5.38 gears with NV3500 trans, Stak 3-speed tcase and 39.5 Iroks. My speedometer is nowhere near correct.
