Trouble getting final set up right.
Those settings should be fine. Let's get back to simple idle data. 30 second datalog at idle and at operating temperature.
I adjusted the IAC Steps last night. Noticed it was dropping below 3 and would hit 0 occasionally so bumped up a bit. Hovers around 8-12 or so at idle now.
DashBoard1.csv is my short drive to warm up.
DashBoard2.csv is the 30 sec idle a few min after I returned.

How is it driving now? The idle log looks real good. I see a few spots on the drive log, but some of that should learn out.
Seems to run ok but haven't gone too far. Had 1 small backfire on warm up drive but overall ok.
Exhaust smells a bit rich but not eye burning or anything.
Just did short drive on small highway with hills (DashBoard3.csv) and made up and over without issues. Still has some response and smoothness concern but hasn't gone far for much learning I suspect too.
Several 105 faults and not sure this is a concern?

Did you disable DFCO. Can't remember... This will solve many driving issues and random 105 code.
Good to here it is driving ok. Next I think we need to adjust the idle AFR. Very similar to adjusting idle mixture screws on a carb, just don't get dirty....
Get engine up to temperature. At idle, in park, adjust your idle AFR up. Make sure to "Send to ECU" after each individual change. Try a half point at first. Monitor your vacuum on the handheld of a gauge. Lean the AFR until best idle quality and highest vacuum. Then rich a couple 10ths to be safe. Let it learn for a bit. Look for small trim numbers. Then pull plugs to read and verify your idle tune.
With this number you can build the rest of your AFR table. Full throttle AFR, I set a little richer than idle AFR, for safety. Part throttle AFR you can lean out a bit. If to lean at cruise, you may experience some heat increase and/or light surging.
At this point, I highly recommend EFI university $100 online course on tuning. This will give you a better understanding of AFR tuning.
Ok thanks and good plan - Yes I raised DFCO enable temp to 300 which I guess effectively shuts if off.
I won't be able to work on car for a few days but will do AFR adjust as described as soon as I can . A couple of questions and yes I'd be interested in the EFI tuning course.
1- when I get - Idle AFR Target - number for highest vacuum and best idle (#01 on screen shot) / how much higher should full throttle be (WOT #05,06,07) and how much lower should part throttle be (Cruise #02,03,04)?
2- I did a sort filter on DashBoard3.csv and noticed that all the 105 faults happened during higher RPM's (like 1850 to 3000) and higher spark advance. Any significant s to this? Any concerns with this fault happening?
3- what are details for EFI tuning course like when and how long, etc?
Thanks again.

That is an offline screen. There should be values in the boxes.
There is no "what is best" for AFR. You will need to find the best for your combination. Many factors dictate....
The DFCO disable should solve the 105 code.
The course is at your own leisure. I think a dozen videos, with a test at the end of each one. You could do it all in one day.
Hello - Got back to it and adjusted the Idle AFR Target from 14 to 14.25. Idle seems the same but I think it leaves idle to accel a bit smoother.
Here's photo of current settings plus I have a driving log and a 45 sec idle log if it helps.
Still some ruff patches throughout the full range and sometimes the transition between cruse to accel is a bit jerky but overall is better.
Any suggestions on other settings?
Thanks - this has really helped.

Many of these same things have been discussed and solved in other topics. Every combination is different. You to find what works for you.
