Thread: Digital Dash Startup Question

    OK thanks. I printed that out and did read it beforehand. I checked with my multimeter (which I guess can’t read the drop out quick enough), but I see the article mentions an oscilloscope. Looking at my datalog I can see the square patterns. I'll see if I can attach my datalog. Sorry for being a pain.

    Yes, that's what viewing a System Log is for (oscilloscope/square wave pattern), as opposed to a regular datalog. Crank & Cam A/D means Analog To Digital. It's the actual signal voltage, not the +5V or +12V reference supply voltage.

    OK, that makes a lot of sense now. Thanks for the insight on Crank & Cam A/D. I was trying to figure out what that stood for.

    Danny, I've been searching & reading regarding my hard start issues, and I'm thinking about changing/lowering my Cranking Fuel values. My question is my car will crank for a while, then when I let off the key, it will stumble like it’s going to start. Does this sound like too much fuel? It does not matter if I open the throttle or not.

    My After Start Enrichment numbers look high to me.
    167% @ 40°F
    153% @ 60°F
    138% @ 80°F
    And they eventually drop off to 114 @ 140°F. I'm guessing this would explain my rich condition when idling. Am on the right path, thinking I should lower the percentage some, at least 40, 60 & 80°F temps?

    This is not hard. Play around with the numbers and see how the engine likes it. Andrew

    Your After Start Enrichment % values look fine to me.

    No, the After Start Enrichment % is only active for several seconds of idle after startup.
