Hi everyone
so got my X3 sct and popped over a 94 custom tune to my gt500s ecu, now after the tune, I also did the following
since the gt500 is equipped with the track pack options I used 3:73 as the rear diff ratio, and since my tires are 285/30/20 (not F1s) I set the rev/mile count to 755...
First off? Is this information correct to set to the tune??
and also, after flashing the revs/mile and diff information, my navigation popped up a "navigation fault" error on the screen upon start up but the navi works... anyone know how to fix this??
