I cannot seem to get my previously dialed in AutoVE and MAF tune to run any richer than 14.9 average. I had the VE nearly perfect under 4K RPM then did the same with the MAF which I added back in. Now all of a sudden it runs lean.
Could it merely be the temperature change? It was all dialed in between 55-65 degrees F and the weather is now 28-35 degrees
I did rewire my WB but it seems to be behaving like it did before. Weird thing is if I run the bi-directional controls and command say 13.7, I get exactly 13.7 when I let it idle on its own it seems to hunt up and down from 14.4 to 15.3 and averages 14.9. Its seems like something is trying to force the 14.9, I even tried a new tune with 14.2 commanded and still averaged 14.9.
My wideband guage seems to display pretty erratically but comparing against my old dialed in logs it did the same. Does anyone else's wideband readings seem to constantly fluctuate?
Any ideas on what to try next? I even threw in an old CL tune as the WB is wired in to emulate the NB. Guess what the average AFR was? 14.9
