the chunky drops in the KC Learned indicate knock like arround 4000-4500

Also the afr (measured is running about 5% richer than commanded AFR this is fine and safe just costs you some power.

It goes rearly rich on initial throttle application so likely needs the load limits corrected again not critical, it will just stop the car bogging if you jump on the throttle at low rpm

the two runs here one has knock and the next doesnt, see how the KC learned curve is pretty smooth in second run , but in first run its all chunky and jagged thats knock, again not super bad.

Maybe try a different brand of fuel some are way better than others.


if its still same I would smooth the ignition timing in those problem areas.
But fix up the fueling by taking about 4 or 5% of the maf flow values that will get your commanded and measured afr on target .

then maybe the load limits.

Thanks for checking it out!
So for now, even with this gas do I still adjust the MAF values?

Just adjust the MAF values by Dropping the values 4-5%?
Is that called MAF scaling?( just making sure I know the terms and such)

I Know that I can use Romraider to do the adjustments. Is there a good tutorial or video for learning how to do this?
