ECMlink I think I'm a little rich. (log attatched)

[ErikTande]

I did my first real tuning tonight. I recently installed my 1000cc injectors, afpr, walbro 450 and new fuel filter. Fuel pressure is 37/38 psi, and I did a boost leak test tonight all the way up to 24psi right before this log, so no problems there.


I got it idling correctly and took a cruise log and used MAFCompadjust to smooth things out. That changed my airflowperrev a bit, but I read that doesn't have to be .25 depending on your setup.

Anyway, it's idling and cruising ok now, so I did a couple pulls. Everything seemed ok (a little rich maybe, but ok) so I cranked the boost up to 17.5 and took the log attatched. There's a couple 3rd gear pulls at the beginning, then I cruised home (I had a little fun in 2nd gear a couple times as I got closer to home, 17psi is fun)



Anyway, how do I tune my WOT? Also, when I'm cruising, even slight or moderate acceleration is dipping down below 11's for AFR, I assume that's too rich for 20-30% throttle. Or is that fine? Sorry, total newb here. Log is attached, I let it idle for about a minute at the end.

Thanks!

I'm on my phone and can't view the log. But after you used the mafcomp feature, did you go back and manually see if the points are smooth? The feature usually doesn't make a "smooth" table. Quite possibly saw you build boost at that 20-30% throttle on the pull, and adjusted for the boost. However while cruising, you may not be at that same threshold therefore your rich.

As far as WOT tuning. You make a pull, keep an eye on your wideband(you do have. Wideband and not judging off what link tells you right?). After your pull, go to your table and add or subtract fuel depending on rich/lean condition.

Yeah, I smoothed them after doing the adjust.

I always have an eye on my wideband, and it was dipping below 11 quite a bit during the 3rd gear pulls, and even when slowly accelerating.
