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%
