What is your initial crank advance at and what percent is your initial injector table at? I leave it at 6 degrees and 120%, which seems to work ok. Even then if I let the car sit in freezing temps too long it will take awhile to crank or drain my battery before it does crank over. As you stated once temps get 40 degrees or better it cranks just fine and yes, all of the driveability issues do become a thing of the past. It is just getting the stupid thing to crank in the cold. MAP is a beautiful thing, I will never go back to MAF.

So far I gained 2 mph and 2 tenths off the AEM. I am sure I have a few more tenths to go, although I don't see my car hitting 10s without a built motor.

 

Im glad you got a dose of the "Ivey Tune"! I cannot wait till he works magic on my AEM. I am really looking forward to it

Ivey-Tune all the way
