O.K. guys and gals (?) need a sanity check.

Been studying Mr. Prick's wideband vs B3601 spreadsheet.

Does this apply to the use of a Wideband using a Serial Connection? Obviously, we only have the WO2AFR1 and WO2EQE1 Pids. Specifically on the Innovate LM-2 it uses 14.7 as the 'stoich' value of gasoline. In the LS1 B3601 stoich is 14.63.

1. Do I have anything to 'worry' about. And how would you change it using a pre-defined WO2 Serial Pid?

2. Would it just be simpler to change B3601 to read 14.7 (to match wideband stoich)?

I am in the process of installing a fresh wideband o2 sensor..Want to get it right.

Thanks..

With Innovates stuff it is programmed via the LMProgrammer software,
what ever that is the V2 will see/show.
Converting serial Lambda to AFR (http://forum.efilive.com/showthread.php?t=12675&highlight=serial+afr)

I use ({GM.EQIVRATIO}/{EXT.WO2EQR1}) for BEN and ({B3601}/{EXT.WO2EQR1}) for actual AFR. (reference only)
If {B3601} is 14.63 & your LM-1 fuel setting is 14.7 then yes there is a slight difference.

I personally don't use {GM.AFR} anymore.
See this thread for the difference between {GM.AFR} & {GM.EQUIVRATIO}
Commanded AFR ≠ {B3601}

I thought {B3601} was just to convert EQ into an AFR value,
I was wrong on that.
Changing {B3601} will have an effect on fueling even tho it won't change the commanded fuel & PE tables EQ values.

I think a lot of people are setting {B3601} for E10 these days.
