    This should get you close, and you can tweak it from there. Double check the units your tables are set for and be sure they are set the same as these before you copy/paste.

    You should also make changes to the offset voltage table, if the data is available.

    Finally, you may need to add 50% to your Startup Inj Scaler. You may even need to double it to get your cranking fuel inline.

    Thank you! I will say I've always had to remove fuel from the crank fuel tables I've never added any before.

    Correct, by increasing the scaler, you essentially "leanout" the startup pulse volume. Kind of counter intuitive. Requires less work in the Cranking Fuel tables.
