I set the afr to 12.3 and did another scan. The afr % error dropped to -4%-5%. Staying around 1-2% rich/lean throughout the wide open portion. At the very start and end it showed 12% lean. But that was at the part where i was first in and out of the gas. So it looks better. Maybe tweak just a bit more.
Also my fuel trims went to 0 stft and 1.6% ltft. Someone asked earlier.
I will play with it more tommorow.

Maf is clean. I do a quick check of things before I take it out n run it.
And yeah its tough tuning on the street. Only place I can safely do this is 12 miles away. Nice straight smooth road. Not much traffic. Only got one run in tonight. Deer coming out more this time of year. Thats the last thing I need.

I tried to get the afr error a little better at the 12.3 commanded. It ended up getting a little worse. Showing 2-3% error lean through the duration of w.o. the scan befor was showing -4-3% error but through the duration of w.o. it was 0-2% with some 0s and 1s.
So I stepped back to the better tune and set it to 12.5. Scanned and my error is a lot of 3-5% error. So I copy/ pasted by % half. Try again tonight and hopefully thats it.
I did get a smidge of kr around 4000ish rpm. Showed .5-1 degree which I corrected in the timing table.
I'll give it a try again tonight.

I got her finished up. Runs pretty strong were its at. The error moves around maybe 1-2%. But thats probly as good as its ever gonna get street tuning. My maf curve is smooth all the way through.
