    Anyone know if there's a trick to do a Crank Relearn on a MAFless setup?

    From my understanding the crank relearn procedure won't work unless there are no DTCs set but SD setup requires 3 DTCs...

    Here's the log along with the channels i was logging.
    Wideband isn't wired up to the logger through EGR yet, but watching the gauge it looked ok for the majority of the time.

    Yep, it was the pump.
    The walbro i went to put in was actually a 450, and had to make some mods to the assembly but it all worked.

    Ok, tried using my brain a bit and figured it out.

    Flow rate = g /sec

    Then used the raceworks calculator to work out the effective lb/hr rating of the injectors, so 375cc @3 bar = 35.7lb/hr and...

    Ok, unfortunately I can't seem to find any data on what they'd flow at 58psi though

    Ok, will do.

    Just to get an idea of the final product, once I've adjusted everything, what sort of fluctuation should I see in the wideband reading overall?
