    Default E38, 427 LS7 Hard Crank

    Hey guys, I have a car here with a 427 and a pretty healthy cam that will not fire up unless I manually open the TB with the gas pedal. Fuel on crank is spot on as well as crank airflow...is there another table I am missing?

    How are cranking fuel and airflow "spot on" if it wont start?

    can you log and see what airflow, throttle position, and injector pulse are doing on cranking?

    Post the tune.....

    But at a guess, try increasing {B1832} a bit. Add 20% across the board as a test, maybe even try 50%
