56v a lot once the bike is up to running temp. One thing he noticed on the logs is that although the O2 sensors are operating in the normal range (between 0 and 1 volts), the front O2 sensor varies a lot more than the rear, whereas the rear seems to stay around.

I have also tried having them in various on/off combinations just to be sure.

Closed Loop is set to 1 (on) and Adaptive Control is also set to 1 (on). I have had the Dyno Jet tech review multiple logs, and we have tried several different tunes, all with the same result. I will occasionally get a few hits at the very beginning of the session, but then nothing at all for the remainder of the ride. When attempting to run Auto Tune, however, it constantly displays NBF:0 NBR:0 throughout the session, indicating that it's remaining in open loop. I have not had any problems with flashing the bike with the canned tunes they provide and the bike runs pretty good, albeit my gas mileage seems a tad low and I was hoping to fine tune it using the Auto Tune feature. I have a 2008 Sportster 1200L and purchased a Power Vision to tune it with. I've been working directly with a tech from Dyno Jet and we've reached the point where he can't think of anything else to try, so I was hoping to share my issue with the forum to see if anyone had any ideas or suggestions.
