Default AN Auto Tune AFR Question

I recently changed my Afr from 13.9 to 13.3
And didn't like the resukts very much. Is 13.9 too lean?
What do most of you use for a target?

Did you not get it tuned after the cam install? Having an autotune is sorta a work in progress, as you can always tweak your tune. What base map are you using? There are some variables in setting up your AFR, ie. Elevation, mods etc... I've had my autotune for a couple of months and i'm constantly making adjustments to see if I can get more. I find my bike runs best in the 13.7 range up to 20% and slowly adding fuel up from there... I could probably post a pic of my afr table in a little later, my bike hauls since I've started tuning it...

I've had 2 tunes that wernt very good. I went to people with good reps, but know HD .
I feel good with 13.9 . But was afraid it might be lean.
I would love to see your table.
I was also thinking of adding like 3 degrees ?

I've added 6 degrees everywhere from idle on up to redline. My bike ran like shit at 13.9,what are you tuning for? Power? Mileage? Depending where the 13.9 is on your map, yes that can be fairly lean. I'll post up a pic as soon as I can get these crazy kids into bed...

The gain from the advance is huge, also setting up your accel pump is a big difference...

+6? I have mine at +4 as per Lloydz recommendations BUT I also run 87 octane. I'm interested in seeing your map also. Mine is set to 13.7 up to 13.4 at 6500 rpm. I attempted to mirror A/F of posted good dyno runs.

Ride safe.

Is lloydz recommendation with his timing wheel installed as well? I know everyone says the pcV only adjusts over 2500 rpm but I've never seen any data to back this up, the pcV software shows it is advancing at idle and if you take the advance away at idle up to 2500 in the software you can feel it so until I see data that proves otherwise that the pcv doesn't do anything under 2500 rpm i'll go with what my butt dyno is telling me...

My +4 is from the wheel only. In the PCV, it is set to 0. I have heard the same also but never messed with the PCV setting as I installed the wheel before the PCV.
