    How to alter ign. timing on 318iS M42?

    I'm concidering to supercharge the little 4-banger, but it has 4 separate coils and no timing mechanism I can find, other then computerized. Any ideas on how to adapt timing to boost in this set-up?

    Thanks,

    Hugo

    Hi!
    Change the inj.system to sometihing else (haltec etc.) or disengage Motronics own to replace it with some stand alone(?) system. The latter may be very difficult. Better yet - find a shop that tunes Motronic systems. Bench the car and you have good fuel and ign. maps. This costs here about 200 to 300 .
    ...didn't help (uh)?

    Well, it is clear in the sense that.....

    changing the current set-up is not done without proffesional help or replacing it completely. I'm considering putting the complete Megasquirt'nEDIS set-up on, I'm building it for my 2002 as well. But I was hoping someone would come up with a cheap and easy answer...

    MSD should have something for a 4coil pack

    ignition upgrade/amplifier. I just saw it in their catalog. You may also want the fuel pump booster from MSD.
