[BlackStealth]

I left the I/J field blank and let the AF target map take care of it initially because it's already rich to begin with. The factory AF tune is around 10.x and I tell the AF target map to tune for 11.0 for that transition. Later on after I'm satisfied I can bump it up to 11.5 AFR or manual tune it myself.

On my car when I let up on the throttle, I always get a rich spike momentarily (probably because the FPR couldn't regulate fast enough). This rich spike is essentially bad data that needs to be ignored by the AF target map. The best way to do this is to increase the throttle position percentage to a high value, and increase the feedback cycle rate so the I/J map changes slowly.

When making a new map from scratch, I'll temporarily lower the throttle position percentage to a low value, and lower the feedback cycle rate just to speed things up. And manually adjust the I/J map cell if it was affected by bad data.

Now only if we could somehow tell the AF Target map to ignore the bad AFR values just temporarily for so many milliseconds it would make the AF Target map a million times better.
