Timing tips

Yeah, I can tune on the fly while it's running and log it easily. Bumped the idle timing up to 20 degrees and surprised it didn't make more of a difference in rpm, but I think it did help my stumble issue. I think what was happening there was the timing would pick up when I would blip the throttle before starting to slip the clutch, then as the rpm fell as the clutch engaged it would drop back into the low timing zone and the engine would lose power and stumble.
You have an IAC right? The iac will try to maintain a target so it may be compensating for the increased idle rpm.
