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.\u00a0 This builds the timing to be closer to the MBT table.<\/p>\n

The result was more KR in the midrange, which is not good.\u00a0 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.<\/p>\n

Uncorrected HPtuners output at peak HP.<\/p>\n

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.\u00a0 I will take that out, and look at the spark level desired at 6800 rpm.\u00a0 I also plan to re-test AFR at 12.8:1 instead of current 12.5:1.\u00a0 I tested that in Tune 2 but I want to recheck.<\/p>\n

This chart shows the LOSS of timing due to KR for 7A by increasing the timing, except above 6000 RPM.<\/p>\n
