so i was tuning on the truck today and made the switch to e85, which is amazingly simple. i just changed my fuel constant and off it went. when i started it wouldn't idle below 1000 rpm. i started messing with the idle verses temp settings and thought i'd see what kind of control it had. as soon as i passed 1000rpm on the table, the idle dropped right down to 800 and stayed there. i goosed the throttle and it settled down at a 1200 rpm idle, so i shifted the idle table to above that an it dropped right down to 800 again. so do any of you super tuners have any idea on what's going on here?
