Calc.VET: correcting MAF and calculating VE (in single log)

[WeathermanShawn]

I still don't understand how is your fuel trim derived BEN any different from trims alone, or the classic BEN. Care to explain that, and I don't mean anecdotal evidence that ends with '..but it works for me' but have an actual derivation?

This Calculated Pid is the definition of the 'Airflow Correction' Term(s).

"iff({CALC.PE},{CALC.WO2BEN1}, {CALC.LTFTBEN})"

{SAE.MAF.gps}*({GM.DYNAIRTMP_DMA.C}+273.15)*3445.2/(5.669*{SAE.RPM}*{SAE.MAP.kPa})*{CALC.SELBEN}"

The first few terms defines PE Mode, the last two say use WO2BEN if it is in PE Mode or LTFTBEN if is not in PE Mode.
