I have the wideband output tied into the PCM for logging, but can't get it to work right. The numbers I'm referencing come from peeks at the gauge while driving.

And the gauge had another face for lambda, so I'm pretty sure it will read 14.7 as stoich, even with the E10 crap we have at there pump.

Yup, peeking at the actual gauge is how I'm getting numbers.

I'll see if I can change the digital readout to lambda. I don't recall that in the instructions. The gauge face has 1lambda at the same spot on the outer led sweep as 14.7afr.

I've tuned my Beretta as "14.7 stoich" according to the wideband even though it also runs E10...and the actual afr is probably in the low 14s. I don't think the wideband knows or cares.

Hmmm. Similar results, even with a different calibration on the MAF. WOT spikes lean and then comes down to mid 13s. Low 12:1 idle initially, but corrects itself to 14.7 with STFT pulling a ton of fuel out.

I'm new to the MAF and its effect on fueling. All my OBD1 stuff has been speed density. Thinking about disabling it again to do some VE table refinement and reduce variables. As I recall, it ran a fair amount better that way, too. The STFT and LTFT are reporting correctly in the log, so I'm thinking that may be where my time is best spent in the immediate future.

Thoughts?
