Does any one know anything about getting digital speedos calibrated?
Im re-gearing my f4i and since the speed signal is generated in the trans it will be farther off than it is now (10%).I know it is a 0 to 5 volt switched signal so im guessing that it is the frequency of the signal that determines speed. I also know that Superlift makes recalibrators for full size GM trucks and i was wondering if they might work.Any info would be greatly appreciated. thnx
