It's part of the MAF scaling tool done by vgi:

So far most of my effort went into finding the correct MAF scale such that AFR is consistently 0.3-0.5 richer than commanded in order to keep the knock sensors happy. I messed with the load limits to tame the lean spikes at lower rpms. You may or may not need to do the same as you may have different intake/exhaust components. Best to do a few WOT runs to see how your AFR plot looks first before making any changes.
