AutoVE with serial wideband Lc1

[joecar]

An EQ BEN is not pre-loaded with the latest software?

Good idea, I'll suggest this to Paul.

[COLOR=#b22222][ keep in mind that LAM = 1 / EQR, so EQR 1.1 equals LAM 0.909; i.e. dividing by EQR is same as multiplying by LAM ]

I'm not grasping what you are saying in this part.

In my example, when i said EQIVRATIO I should have said BEN. BEN is the number I was thinking. Thanks for explaining that out for me.

Thanks guys,

I'm simply saying that the calc_pids.txt defines BEN as being multiplied by EXT.WO2LAM1 which is the same as being divided by EX.WO2EQR1

[ remember, we had just said that BEN was the comparison of commanded fueling and wideband measured fueling ]

Yes, in your example, correct, BEN.

{GM.EQIVRATIO}/{EXT.WO2EQR1} \
{EXT.WO2AFR1}/{GM.AFR}------------> Serial Wide Band O2 BEN factors
{GM.EQIVRATIO}*{EXT.WO2LAM1} /

The 3 forms that mr.prick said above are all identical (provided the wideband's value for stoich AFR matches the fuel being used... which usually is not the case).

The form mentioning AFR is not always true for these reasons:
- B3601 does not match fuel used,
- wideband's stoich AFR value does not match fuel used,
- B3601 and wideband's stoich AFR differ from each other.


The forms mentioning EQIVRATIO, WO2EQR1, WO2LAM1 are always true regardless of fuel used, wideband stoich AFR, or B3601.


Note that the LC-1 has a set-able value for stoich AFR.
