The maf is on the car, I've just now been hired onto this issue. I tried zeroing all adaptive and adders/subtractors/multipliers of spark.

Mid engine swap into a corvair, fires up and runs at 0* advance and when u give it throttle it drops into the negatives, At our witts end with this and have tried alot with the tune, It's a mail...

this is what it shows on the histogram for main spark advance... but the log backs it up on the chart when u drive part throttle or go wide open it uses whats in the .08 section

alot of people straighten the curve with p/e, which I frown upon

Thank you, That's what I needed... Now if it only didn't cost another 100$ to do it

That doesnt change anything.
