Oof, that's some hours.. thought about making this type of post myself.. was being patient though lol.

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?

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..

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.

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?

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?

Well the learning continues..I obviously didn't start at the beginning.
I have to back up and dial in fuel. Never looked at that write up because the car started well, ran well at idle and by monitoring the payloads on EECV dash the only one in the red was ipsibr. I'm using FBGIO on an 03 Cobra. According to the fuel control write up, does the prldsw still get set to zero even though the note says fbgio does not have perload fuel control?
Question on stoich afr.. it was set to 9.8.. I found this first reading from the beginning and set it to 14.64 for pump 91.. car would barely run.
So do I set that to where it needs to be(14.64). If I understand correctly, this will pull fuel out from where it was initially at 9.8. Which would explain why the car would not run.
Having said that, all the things on the list of basic fuel modes will need to be increased?

yep if ipsibr is up there at full warmed stable idle then yeah the throttle stop needs to be opened slightly.

No I never wasted time on hit tracing as I find it pretty useless.

Excellent, that explains what it did then. Thanks! Will try the throttle stop next.

So that went well. PATS is enabled and the car starts.. Warm idle stabilized and ipsibr is .1xx to.2... so follow the instructions and open the throttle screw?
Another question on function: Is hit tracing enabled?

I was able to find the PATS code and copied the cells and moved it over. Saved it. After work I will load it and turn PATS back on and see if I did that right.
