    upgrading my fuel injection computer

     



    After 10k miles I am finished with individual throttle bodies. 1200 RPM and up was no problem. It's just the constant battle of the idle. 80% of the time it's perfect.
    Then a little distortion and the idle is inconsistant. I installed a new EM-TRON
    ecu and 8 coils. The engine has never run this good. It has 2 knock sensors and each cylinder is tuned to it's own liking. If one cylinder decides to knock, the ecu retards it till it stops knocking. As soon as the cylinder will take it back, it resumes the spark map. With sequential injection and phasing, it runs like a sewing machine. I built a trigger system using the stock distributor. Looking forward to it's first trip up the Pacific coast.

    Your engine is just beautiful, and the craftsmanship is fantastic. Thanks for the EmTron name, I've bookmarked them for future reference. What software package do you use for mapping?

    Curious as to why your crank piece seems to be missing "tabs" for the proximity sensor to pick up? Perhaps I am mis-labeling the parts or using the wrong terminology... but it seems it's missing some tits to the right side of the prox. sensor in that lower picture... or are they just not needed?

    The software package is in the ECU. The missing tooth is a reference mark for the trigger. I am doing the final on the installation as i write. I will send more data when available.
    Sorry for the delay in answering. I have also been busy with a new Koultool I am about to release. It will lap in the flair in hardlines.

    No sweat on the reply! I'm just thankful you'd share the knowledge! I am considering changing my car over to a crank trigger arrangment and have been "studying up", as it were....

    BEAUTIFUL engine kerker. gotta love the flatheads.
    I must have missed the back-story, but I always hate to hear of failed attempts in setting up ITB systems. having been down that road myself, and won, I know it ain't always easy. the rewards can be great also however.
    But in the end, it's better to have a great running engine than just a great looking engine.
    Can you direct me to a pic of your flatty with the itbs still on it?

    Thanks,
    Russ
