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?
