FP3 Quick question about AFR
I was looking at my sensor data after I had run a good auto tune session the other day and noticed that the AFR is at 21.2 at idle . Can someone explain to me exactly whats going on here . I have been trying to get through V&H for awhile with no luck , so I though I would try here as well .

Ok , so I just got off the phone with V&H and I was told that it was nothing to worry about . It appears the older 4 pin set-up does have that " flaw " , as long as the AFR's in the table are showing accurately , I am good to go .

really? well if it's a flaw then fair enough, hopefully they will fix whatever it is?
Where were you reading AFR? I see "Target AFR" in the view sensor data but give or take a little AE DE or PE shouldn't be that far away from the AFR table for that map (14.4 for the 2010 Touring) especially when you are talking about at idle
weird??

I agree , The guy I spoke to said he noticed that happening while one of their bike's were on the dyno . This morning , I fired up the bike while I had my sensor data on , showing the AFR screen and for the first 10 seconds or so , it read about 14 give or take , then the needle just jumped to the far right , up to 21.2 again . I went for a ride and the bike runs perfect , no popping and tons of power , so no worries . Not sure if there will be a fix for it in the future , but I was told it was nothing to worry about .
