Default Map 7 Log Review Request - 09-14-2019, 04:30 PM

After running Map5 for a while with ~E40 fuel and seeing 17psi with 10-12 degrees of timing, I_avg at 0.6, trims at 35 maximum, and fp_h dipping only to 14, I got brave and decided to try Map7.

But first, I mixed in some more ethanol to get up to ~E50, and was able to also mix in some race gas to get the 'base' fuel up to about 96 octane.

Of all things, I forgot to turn off traction control, and you can see the throttle and timing intervention. I think there was enough octane, but trims maxed out and AFR looks real lean in that area. I don't know if that was due to the traction control, or if my fuel pump couldn't keep up? After seeing how lean it was with the maxed trims, I backed off and switched to Map1. Any insightful feedback welcomed.

Ideally we’d like to see some logs w. Traction fully disabled.

Could try bumping up fol to 90 as well, might help bring the trims down a bit .
