Default Cranking PW

Something occurred to me and I haven't been able to find an answer.

Does the fueling while cranking take any account of the Manifold pressure or does it squirt the same regardless of throttle position?

I assumed that the % numbers in the cranking pulse widths was a multiplier for the VE table, but it seems that it is a percentage of REQ_Fuel.

Cranking does not use manifold pressure correction.

Right, so my habit of sitting my foot on the gas pedal while cranking is probably messing up my attempts to tune the cold start?

Probably. It generally needs more fuel if you floor it.
