i have a patch for fbgi0 for perload fueling but its for premium members only for now so you need not worry about that for the time being.

9.8 is e85. pump averages 14.079 in the usa as its e10 blended.

you set it for the actual fuel your using i have a chart at the top of the fuel write up

not sure what your referring to about baaic fuel modes being increased but first you need to dial in fueling.

Local pump is 91 no ethanol, but yeah it's probably not like that everywhere so best to put in 14.079.
What I mean is currently the bin file has 9.8 in the stoic afr in scalers. I changed it to what I should run for gas and the car wouldn't run.
Since I changed it from 9.8 to 14.64 the car wouldn't run. Changed it back, all good. Maybe I'm changing the wrong one?

Obviously its leaning out too much to run.

Go kick up the maf 35% and then dial it in

Yes. That makes sense. I knew it was making it too lean, was just unsure where to make the change.
So I have a BA3000..I used the data from the drop down in the maf section. Is this the same table to increase 35%? Just the cells on the right..correct?

yep

Well I successfully integrated the wideband into Tuner Pro. Although it's not quite spot on. I have an AEM on the way. Conflicting info from the gauge to calling the manufacturer. While I wait I will play with the equation. The screen on the wb actually says for the analog output is a .5-4.096 volt output and gives the formula:
(Vout*4.76)+1.5
Manufacturer says the volt range 0-4.096 with a range of 6.34-14.3. (FAST dual sensor for alcohol, so I just convert the afr readings on the screen.)
I used the manufacturer claim to figure the equation and it was off a good bit. Closed the gap by using what tool said, extrapolated to 0.
EDIT
I could probably just use this?

Next question:
The history table for maf error, that can be used to dial in the maf curve? Am I understanding that correctly? I see it populating 1's in some cells, others bounce around. I'm unsure of what exactly it's telling me.

yeah the o2 sensor correction can be used to correct the maf.

its the fuel error

OK, so O2 sensor correction.. so the one that reads Hist_AEMUEGO_ERR? so I can put that table next to FN036 and multiply the flow rates?
Reason I ask is I've been looking at the MAF_ERR history table..

only if you have an aem uego wideband

wideband should only correct the upper portions where the o2s aren't used.

ahh, awesome. I have one on the way.
so you have to use the longer form wb/lambse *kamrf on the rest of the curve?
