I am working on getting my VE table to a target of 12.5 / 12.8 AFR. Right now, the issue I am having is each time I take away fuel, the values seem to go inverse? I went from 82 in the 80/90Kpa area which initially was about 11:9 AFR to about 11/10:90 at 70 fuel in the same KPA's. I am doing these pulls while driving and trying to hold all variables constant (Shift, Throttle percentage, etc).
One item I see is knock keeps pulling timing in these areas? I triple checked, and there is no mechanical issues inducing knock and knock sensors are brand new? I know rich conditions could cause knock, however this is what I am attempting to correct? I did pull about 4 degrees in these knock areas once, but it did it again in the same area?
Attached is my tune and a pull data, any insight would be greatly appreciated
