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

[WeathermanShawn]

Thanks DMAX:

Joecar has a ton of Links on EQ..so I don't want to butcher his work.

Here is a start on the EQ/Lamda/AFR conversion. A lot of it depends on B3601 in your Tune. I.E. The conversion of EQ is based off stoich..I'm sure Joecar can give you more data. If not I'll get some for you.

For anyone reading along, this relationship has to be understood:

AFR = STOICH_AFR * Lambda = STOICH_AFR / EQR

and, that relationship applies separately in each of commanded and measured contexts;

when you cross contexts you get a correction BEN factor (if you cross correctly):

i.e. BEN is all of these:
BEN = commanded EQR * measured Lambda
BEN = commanded EQR / measured EQR
BEN = measured Lambda / commanded Lambda
BEN = 1 / (measured EQR * commanded Lambda)
. . .
and other combinations using AFR.

The easiest BEN to obtain is the first one listed above.

EDIT: Also check out this calc_pid.txt (look at the last 3 AFR Pids). Joecar breaks down EQ into an AFR conversion..http://forum.efilive.com/showthread....l=1#post140820
