Ringram: I've made some initial tests on a "smaller" cam (220/224) and found that B1650 has an interesting effect. I like it so far but the verdict is still out on the light throttle surge. I found that reducing it too far, resulted in a hanging idle when cold and the normal ECT correction table needed a lot of work to try and correct it. So I increased it to about 80% of the stock value and it seems fine. I still get a small amount of surge so may need to work on some dynamics again.

Hymey: Those tables can give some good results, don't they. As mentioned, I zeroed out the few cells around 0 RPM in the Proportional table to help with idle control. I'd found that my engine idled better if it was commanding slightly more air than it really needed. The problem was that the Proportional table would pull too much air out and the idle would go rough. I was consistently adding 0.5gm/S to the min idle air, then it would learn down and run rough again. So I zeroed the cells and all is good now. Min idle airflow is what I want it to be and the ECM does not remove addition airflow.
