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.

91 Beretta "SS" - 260hp 3400 MPFI / HM282 5spd (7730/$A1) sold! for crazy money...but I miss it
94 Silverado Z71 - 300hp Vortec 357 TBI / NV4500 5spd (7427/$0D) gone but not forgotten
96 Beretta "T56" - 4.8 LS RWD swap / 6spd (0411/2156)
01 Silverado 2500HD - stock Vortec 8.1 / ZF6 6spd (0411/8322)

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?
