Cranking / Base Injector Pulse Relation

Post by Corey872 »

What is the relationship between the Cranking fuel trim and the Cranking Base Injector Pulse and Overall fuel trim? For instance:

If I change 'overall fuel trim' does that include 'cranking fuel trim'?

If I change 'cranking fuel trim' does that also add/subtract from cranking base injector pulse?


In previous versions, I had changed cranking fuel trim to get reliable cold starts on E85. With newer versions of Kpro, I see base injector pulse has been added. So now that I have rebuilt to 12.5:1 CR/turbo, I want to take advantage of the temperature/pulse curve, but would like to know how these settings inter-relate.

Thanks
Corey
