ok heres the deal. i kinda want a speedometer back. i tried adjusting them with gears after i did my rear end swap and they didnt mesh right. now ive done a motor swap and removed the computer. since im always changing gear ratios, and tire sizes id like to know how programable those sending units are for autometer. id use it with an autometer speedo but i want to be able to adjust it for different rear gears instead of changing gears in the tranny.

thnx
