Hi Mackei23b - sorry do not fully understand! (not unusual!). Would the cam sensor then enable the ECU to adjust the timing of the injection for each cylinder? How critical would it be to get the cam sensor working? I cannot find whether or not the original MBE ECU has a specific input for the cam sensor, not much info on the MBE website!? The Omex 600 does not have a specific input for the cam sensor , but could one use an auxiliary channel? Thanks. Garth
