    There are a few common failure modes with the Ficht EMM. They are repairable and once repaired they tend to run just fine.

    Up to you whether you convert the Ficht engine to carburetor or keep the Ficht system with the engine.
    Why are the injectors so tempormental as far as resistance with emm?. Why is there a range of resistances?

    Are you referring to the flow compensation numbers for each injector? That has nothing to do with electrical resistance.

    All Ficht fuel injectors have the same resistance specification, a fairly low ohm resistance. These are high current devices, driven by timed 45 volt pulses, controlled by the EMM.

    You can find more information on how Ficht works via my signature links, in the Ficht section.
