    Base timing is still dead on 0 but from a symptom stand point it sure sounded like a good thing to check.

    The engine seems to visibly shake more when idling than I remember, I dropped off the...

    Hi Fast,

    Good point.
    I was thinking of rechecking the base timing again, the engine certainly feels flat almost like it's lost timing....It would be great if it was that simple, sounds like...

    My TBI Vortec headed 94 G20 conversion van doesn't seem to be running right at the moment, the engine just feels a bit flat.

    It was like that when I parked it up a few months ago, I thought I...

    Your headers might glow red if you were on a dyno at W.O.T. but I'm guessing you weren't, so that's not a good look.

    Can you post your current .bin file so I can have look and compare to mine as I...

    Something doesn't sound right, I don't think you should be maxing out your VE table just off idle and then requiring less VE under higher load/RPM.

    If I was setting up for a larger sized injector...

    Spark Latency table for MSD modules

    Not wanting to hijack the the 8 pin ignition modules thread, I thought I'd ask a question here.

    From memory I set the "Open loop Idle Temperature Threshold" to it's maximum of 151.3 and that keeps it open loop at idle, unless the engine goes above 151.3!

    It's hard to get my heavy van moving when closed loop wants to keep it at 14.7-1, early PE helps to take over where AE runs out and certainly makes my WB AFR's look better under moderate load.

    If you're hitting 100% duty cycle at 5200RPM then I'd say you need to up your fuel pressure.

    You have the temperature for closed loop activation set very low for some reason and I'd reduce the time it takes for PE to kick in.
