using 14.047 for desired AFR and not 14.63?

LOL. I've tuned in lambda since day one, but switched to AFR a couple of months ago.

I mainly tune off of Lambda and reverse it to EQ. I am not sure why I do it that way. Maybe toooooooooooo much time with Ford crap.

Maybe techII has a PID that tells where the ECM is on the B3671 table? That would give you the AFR that the ECM is basing all fuel flow calcs on. Though no doubt depends on which OS you are on.

It has been a while, but I think the Tech II shows target AFR and % of E on flex fuel trucks.

Use/speak/think/breathe in terms of EQ...

You should have locked this thread after this post, Joe.

Isn't EQ1 based on AFR?

It seems to me the PCM generally does all of its work using EQR, and provides the AFR pid as a matter of courtesy/convenience/information.

If you really want me to lock it, I will...

AFR is still important for determining injector pulsewidth.

It just seems like this thread is a mile long,
it has been informative tho.

Does anyone have a dbf for something like an 01 Vette and the later flex fuel trucks? Maybe even the dbf for the bin's I posted.

Joecar if I overstepped the boundaries delete this post.

I don't see any problem...

everyone has contributed their information/opinion in a civil manner... ...thanks to all, this is a credit to EFILive forum members...

discussion of differences is fine, everyone learns constructively...


I think mr.prick (his real name) was simply joking about the thread being quite long......but that's ok.

I use both EQR and Lambda from my LC-1 (in serial/digital format)... I like EQR better than AFR, it lets me think easier in relative terms (relative to stoich).
