Quick question about cranking fuel

Can please explain how the ECU uses each of these tables:

Cranking Fuel
Cranking Fuel Trim
Air Temperature Fuel Compensation Cranking
Coolant Temperature Compensation

How long after cranking does the ECU begin using the main fuel tables. And do the compensations add up? Like if the Air temp and Coolant temp are both 35 degrees, does it add/multiply the trims together?

Have you read the information in the help file about these: ... meters.htm

If there are no specifics about how long these are effected then we do not have that information as these are tables that the ECU uses and we have given you access to make changes to them.
