lambda vs a/f

[minytrker]

I have everything set in a/f right now. In order to switch over to lambda what all do I need to change to scan and tune with it correctly. I bought Greg's DVD but it was more on configuring HPT vs EFI.

It might be easier to use EQR instead...

Do you have V2 and are using serial wideband AFR...?

See attached calc_pids.txt... it defines the BEN pid as follows:
"{GM.EQIVRATIO} * {EXT.WO2LAM1}"

With the new BBR release candiate, Paul has added the pids EXT.WO2EQR1 and 2... this means the BEN calc pid can read as follows:
"{GM.EQIVRATIO} / {EXT.WO2EQR1}"

Both are valid, and EQIVRATIO gets you away from AFR... if you need commanded AFR for "visual" purposes, you can define a calc pid for it like this:
"14.6286 / GM.EQIVRATIO"

where 14.6286 would be stoich AFR (use your own value).

Im using V2, would it even be worth it to switch. I have always been just using afr.
