Hey guys,
I've been experiencing what I believe is a bit of a strange issue. My PE commands 12.6 and Im observing AFR though a wideband gauge.
When driving in top gear on the highway at say 1900 to 2600 RPM I enter PE I will get incosistance ratios. About 75% of the time I will get right around 12.6 but sometimes it will be as lean as 13.0 or rich as 12.1
This will happened on back to back pulls on the highway.
This may clear up higher in the rpm range but I've not observed it enough.
I've tuned MAF and VE tables to a percent or two using STFT and LTFT are disabled. Its currently setup to use MAF and VE like stock.
Is this some strange blending issue? I don't understand why it will vary so greatly. Would I be better off running straight MAF or VE?
Thanks guys,
