I am not new to ecm link or tuning with it but i am having a hard time getting my idle tuning set up on the new set up. Car is stock motor accept for hks 272's. I am running fic 1050cc injectors on e85, Fuel pressure is set up to stock pressure. What should i be shooting for airflow per rev with my cams. The idle is set at 1,000rpm but it likes to sit between 950-1050 rpm and air flow per rev is around .27-.28. I can get the car to idle between 14.5-15.3 cycling on the wide band with combined FT bouncing between -4.9% to -10%. Any attempts to change dead time or global or maf compensation will move the airflow per rev anywhere from .25 to .30 i can keep it right in good a/f range on gauge but will just throw my FT threw the roof up to -16%. What should i target for air flow per rev? car idles around 11in manifold vacuum. If need be i can take a idle log and post it up just is confusing me first time trying to set up a car with cams.
