    3B to ADU motronic conversion

    In my proces off rebuilding/tuning my 3B engine I will also convert my 3B single coil ignition to a ADU 5 coil system.

    What parts do I exactly need for this conversion? At the moment I've got this:

    ADU ecu
    ADU wireloom
    ADU hallsensor and campulley (is there another thing on the engine that reads the position of the campulley?)
    ADU 5 coilpacks
    ADU valvecover
    ADU output things (2 pcs)
    Speedsensor and the next to it on the flywheel

    Will the 3B knocksensors fit the ADU engine management?
    Will the 3B flyweel be compatible with the ADU management?

    hope anyone can help me on this, I don't want to miss something when i'm building the engine next week

    Thanx

    You don't need them, just let your distributor in, it has a very nice hall sensor that doesn't fail as often as the ADU/ABY/AAN ones. Just rewire the plug for it so it goes at the back of the engine!

        Mihnea, how is the 3b coil pack conversion coming along, this is gonna be the problem for me even at 1.8 bar. Im getting misfires now! Dont want to destroy my stock rods Its the block im worried about.

        I figured i could use the dizzy to trigger the coils.
