The hardest part of tuning is just understanding what each table is doing. I find that some of the descriptions in EFI Live don't really answer what the table is doing but rather what that table ties into. The throttle cracker and follower are two that I keep getting mixed up and I'm not afraid to admit it!
Growing up with tuning carb's I can see some of the similarities. If I am not mistaken, the TC is what controls the return to idle once the throttle is lifted. If you have a car that the rpms hang after pushing in the clutch I assume you reduce the grams/sec of air that the IAC allows into the motor. One question I have is how much of a change is significant?
I see that this is also based upon MPH. I again assume that those MPH limits control the window in which the TC is active and adding air to the motor.
Are these values added to the desired air flow table? Is this the base table? This now leads to the proper way to dial in the desired air. I have done maps to log grams/sec vs. coolant from a cold start. Once these values are logged I assume this is the actual grams/sec that the motor is ingesting at that rpm and coolant temp. Should these value match the B4307 table? What if the throttle blade has been cracked?? Doesn't this skew the numbers? I am on a big rant with this but know that all these tables interact. I just need a better explaination of the overall big picture.
Oh yeah.............how does the throttle follower work?
I am having some issues with a 02 A4 F-body with a H/C setup that is pushing me to throughly comprehend this.
One last thing is what table controls air on cranking/startup? Airflow Parked?
All this after a couple glass's of Grey Goose!
