    Default Air/Fuel ratio numbers - what does your engine like?

    What A/F ratios are you guys seeing that work well for a Naturally Aspirated BBC?

    My engine seems to want a richer mixture on the ramp up to WOT, (about 3/4 throttle) then it actually does at WOT itself. Is that normal?

    Are you setting up your target A/F table ?

    I have been tuning on a Holley HP system on a friends boat.

    I could email you the target map but we are running E85.
    It's a shame this system doesn't do Lambda.

    There should be some preloaded tables in the files that came with the system that would be a reference for you.
