Today’s test was to add 2 degrees of timing advance in the mid-range except in knock-sensitive areas, and up to 4 degrees near redline. This builds the timing to be closer to the MBT table.
The result was more KR in the midrange, which is not good. Overall today’s test came out as lower calculated HP/Torque than the prior 6G-0312 test except in the 6000-6400 range where it gained 5 hp.

Uncorrected HPtuners output at peak HP.
Reviewing 7A, in a classic ‘Don’t do two things at once’ mistake I took the AFR 0.5 richer at 6400 rpm, so that could impact the tip-over in today’s run. I will take that out, and look at the spark level desired at 6800 rpm. I also plan to re-test AFR at 12.8:1 instead of current 12.5:1. I tested that in Tune 2 but I want to recheck.
This chart shows the LOSS of timing due to KR for 7A by increasing the timing, except above 6000 RPM.
