I know this is a FI thread but I wonder if the principle might apply to any of us backward MFs running carbs along with programmable ignitions. Right now my off-throttle (high MAP) ignition timing numbers at idle are much, much lower: my "trough" is at 800 rpm at maybe 8 degrees (I'd have to hook up the computer to check the table). I'd thought the trough should only be a degree or two. You're saying it can be more pronounced?

Ed, correct. It can be much more, but only at idle. You are using MAP as your load, correct?

Mike, this is awesome for you to sort out. Nicely done.
