Part of the problem there is the internal maps in the PCM are 16 cells wide
as opposed to the 8 in that aftermarket box, so you don't get a clean
overlay. The PCM will switch values twice for each ajustment point on the
SAFC, so it will always be a compromise.
Most of the stand alone controllers like the F.A.S.T., Accel, Electromotive
also work on 16 cell wide tables(32 in some of the latest stuff). At 8 cells
this box is a bit too primitive, IMO.
The factory maps are also not linear, another curve ball in the picture. If
you set that thing up to change at consistent 500 rpm increments, the
mid-range will likely be a mess due to the mismatch.
