What everyone's safe Target AF for 80%-100% on a stock bore, with intake and exhaust? revved out to stock redline? Running PCV/WB2
Likely my next mod, just didn't know where a ideal target was...had read 12.7ish so you'd suggest leaner?..low voltage line will manage the 13.5 in closed according to my findings. So is it suggested to ramp up the target slowly or just enter 13.0 in all cells from 2k and up? Maybe a little fatter in the higher rpm? Sorry still learning. Thanks for any feedback.When I was running stock bore, cam and compression I kept it in the low 14's. Ran a little peppier and cooler. Going into the 13's didn't seem to do anything but hurt the fuel economy. You should throw a TB cam in there.
Thanks for the info12.7 is good for a high compression/big bore setup. I mean, if you want to run it rich, by all means do. It's just not necessary with your current setup. Once you get a cam you can actually put that expensive fuel controller to use.
As far as how to enter it in the cells, everyone does it differently. I've seen people put one value in the 80% column, let's say 13.5, and then a little richer in the 100% column, like 13.3. It's also common to see it get richer at the higher revs, like you said. I think I have mine start getting richer at ~8k rpms?
You even used my screen capture with the voltages as well as my wordsFYI all WB2-ers. I have recently learned that it's possible to re-flash your own WB2 to different target AF numbers in the 0-80% throttle range. Download this software package from Dynojet:
Open the C3 program in the package, then plug in your computer to the PCV just like you would with the normal Power Commander software. On the top bar, click "configure" for WB2. Use this voltage table to enter the voltage number you want to give the target AFR you're looking to run. I used it successfully after installing a BBK on my bike This info was given to me on one of the FB Grom groups. I figured that it would be a good thing to share here.

Yes, if you have a WB2 unit and you set a Target air fuel in the 80%-100% the unit will auto tune..once you turn on the feature.Also if I have the WB2 can I just use a blank map with no trims and fill the 80-100% columns in the autotune table to let the wb2 do all the work?

Yeah that’s what I went with, I got rid of the yoshi with pod map and loaded in the two bros with pod map, zero’d out all the trims but left the ignition table as it was, set my wb2 and the 80% column to 13.5 and the 100% column to 13.3, went to work and back and the autotune trims are now adding fuel instead of removing fuel like the yoshi map was showing. I’ve accepted the trims so hopefully this is a step in the right direction. Any tips on ignition advance as the yoshi map seems to have a lot more advance than the two bros one.you need to leave everything under 80% at 0. the wb2 will fill in this gap if you get it. IF you have it populated under 80 either way you are just fighting the stock ecu.
Right , you did it correct. I was making reference the low voltage output and it controlling the >80% target afr. Seldom do people post accurate information and they always wanna add targets to the 0-60, effectively pissing the ecm off. I'm running a similar config, zero'd ignition tables /fuel and am running a bit richer 12.7.- 12-5
