Thread: Engine Flooding

  1. #1

    Default Engine Flooding

    I'm having a constant problem with my oil filling up with fuel (roughly a half gallon after less than an hour run time). Does anyone have any suggestion on what might be the problem? I've leak down tested the cylinders and I have less than 20% leakage, so I don't think it's the rings. 347 CI, 13.1,CR, Holley MPFI 66LB injectors running on E85.

    Which Holley EFI fuel injection system is this? Stuck injector? Also, read this: https://forums.holley.com/showthread...400#post104400 (MSD Rev Limiter Verification Disable)

    Would that cause the engine to not be able to rev past 2800 RPM?

    I guess if the spark plugs are fuel saturated (or misfiring/dead cylinders), then yes.

    I'm using the Holley HP Multi-Port EFI with the 4 barrel EFI throttle body. I'm also using the older style 6AL with the removable chip, so I don't think I have to worry about it having a rev limiter internally set on it. But I wasn't able to find a base calibration that was inline with my engine, so I downloaded the Global File called 330 40 psi turbo because it was the only one that seemed somewhat inline with my engine set up even though I'm not running boost. Do you know if there is a Global File that would be closer inline with my engine.

    Why would you start with a Global File for a boosted engine when you're not running a boosted engine? What MAP sensor are you running?

    Which MAP sensor is installed, and which base calibration did you use to create your Global File?
    The base calibration you start with, must correspond to the MAP sensor you're using!
    Selecting the correct MAP sensor in the Sensors ICF does not rectify the wrong Base Fuel & Timing Tables.
    Ensure all this is correct: http://forums.holley.com/showthread....ents-Read-This (Initial Checks & Adjustments - Read Steps #1-#6!)

    Remember, the base calibration you start with, must correspond to the MAP sensor you're using:
    For example, you can't use a naturally aspirated base calibration for a forced induction engine.
    This is because the 2,3,5 bar MAP sensor selection only changes the kPa load Y-axis, but not the Base Fuel Table lb/hr
    values (creating an excessively lean map) or the Base Timing Table degree values (excessively advanced timing map).
    You must choose a 2,3,5 bar base calibration or reconfigure your existing Global File's Fuel & Timing Tables accordingly.

    I'm using a Holley 3 bar MAP sensor and I chose it for the base calibration because there isn't a Global File for a N/A Ford 302-351. The only ones that are on there are boosted applications, unless I'm looking in the wrong place.

    The base calibration doesn't have to be specifically for your Ford engine. Click on the "Base Cals" folder. Why are you using a 3 bar MAP sensor on a naturally aspirated engine?

    I'm using the 3 bar MAP sensor because it's just what came in the Holley HP Universal Kit. Thank you for the help.
