Should my Enrich Power Change to AFR Vs. RPM have (-)%AFR at 2000RPM and 2800RPM?

My 2D graph looked like this

It's hard to predict what someone else's engine will like. If that were possible folks could buy decent chips by phone.

FWIW, a 3rd Gen MAF sensor reads airflow in either direction, so if there is any reversion, it reads excessively high. Which to compensate for, means removing fuel in that area.

And that might be enough to fubar the LV8 calculations, and thus the timing.

 

Grump, heres a shot of it. I just thought that it was odd for the AFR to numerically increase at certain intervals , mainly in my LTR powerband.

 

Nope, corrections, AFRs, all move around.
The tuned lengths of the runners, plenum volumes, reversion, all add up for the tune to be *dynamic*.
It's just a matter of making the engine happy.... <G>

 

Allright. Well thanks for clearing that up man.
