stand alone EFI for gen3 hemis

"2. The only acceleration enrichment option in FAST is a "accelerator
pump" type enrichment; MS3 (and MS2) also has a model based acceleration
enrichment that is a bit more sophisticated. This generally has very
little effect on a drag car; it's more useful on a road racer."

I am not familiar with Megasquirt systems, but just for interest, what this "model based AE means?
FAST XFI AE can be adjusted
by TPS and MAP rate of chance, TPS position, and engine temp.

Internal dataloggin feature in XFI is great and easy to use. MS have it also?
