WOT open loop/closed loop

[Bruce]

Then what have you gotten?.
If you looking to correct for atmos conditions varing, then just the input
corrections right.
If you looking for a fixed ideal AFR then you still need to test to find it.

If you looking for max HP per AFR, then the ecm needs to see an input fot
that.  ie the WB takes care of the AFR, but what about the HP part?.  Other
wise your right back to ground zero.
