Hey everyone,
Just updated my power vision firmware as I made some changes to my tune and wanted to flash it to the bike. Flashed it, went for a ride and all seemed good. However, when checking codes I had U0156 (lost comm w/speedo) thrown. I cleared it. Verified that it was cleared then I went inside and made a few additional changes to my tune file. I flashed the changes and figured why not check the codes again. Well, U0156 was back and the only thing that was done was a flash to the ECM.
I Know this didn't happen previously, but with the newer firmware or something... Is this code being thrown due to the ECM flash that the power vision is completing? Seems like this is what's happening, at least on my bike. Just wondering if anyone has any advice or knowledge on this. I don't want to start hunting for wiring issues if I don't need to.

I was starting to think I was going crazy at first, when it was happening. Then I realized it would only occur when I flashed the ecm. Then I tried it on my other bike. My opinion, it has something to do with the CanBus system that the newer years have.

I installed a PV 2 on my 2016 Tri Glide with an auto tune, wide band O2 sensors (6 pin). I updated the firmware on the PV to the latest and it seems to run pretty good with the tune I downloaded and installed on it.
My CEL comes on intermittently mainly when getting on the throttle heavier, and then it goes out, but it does it under heavier acceleration, not necessarily full throttle application.
My codes are P0031 Hist Front HO2S low/open, and P0051 Hist Rear HO2S low/open. Cruising down the highway the 02 sensors are running at 5v and 5.10v.
Is this happening because I'm running the Dynojet Wide band O2 sensors and have nothing plugged into the OEM narrowband 02 sensor connectors? Apparently DJ doesn't do 02 sensor eliminators like they used to do with the Power Commander.

As far as the autotune freezing or acting funny, I found if the wires are too close to other electrical systems it interferes with it. I ran it for a bit and my green screen would freeze up. I had to redue the wires and ran them under the frame on a road king. It really helped the freezing. Still every so often the gauges will cut out. I exit and enter again and they kick back on.
I've enjoyed the experience so far.

Also the OEM Sensor sockets should be occupied by the plugs coming from the TT. If you have this done would propose you triple check the wiring connections to the TT (only weak part of the DJ design IMO / electronic small connectors in a big and dirty wire application)
for testing looks like you are using your PV gauges so Monitor the front and back AFRs NOT voltages. Voltages go to the sensor but you only know if the sensor is working and or is properly wired if the PV can display the AFRs.
90% sure its those finicky wiring connections, there are a pig to get right. They should pop as the wire ends Seat inside the terminal
good luck

For your model year it should be a Target Tune not Auto Tune Module - I have an auto tune for Power Vision.
Also the OEM Sensor sockets should be occupied by the plugs coming from the TT. The DynoJet wide band sensors plug into the connectors coming from the Auto Tune Module. There is nothing plugged into the OEM O2 sensor connectors.

you can use both autotune or target tune depending on what you want to do. I have three bikes including older ones that dont have o2 sensors. So I bought autotune so I can use it on all three instead of buy target tune for one and autotune for others.

I use the AT with my 2001 but with my 2010 the TT
The TT provides full closed loop for every cell on the ECM map and adapts to the Target AFRs real time as opposed to the AT which measures and proposes VEs to update the tune for remapping. My TT and WB lives on the bike doing its thing permently. You can Autotune with the TT in same way as AT, flash the new map and put the TT in the drawer and keep it just for new mapping sessions like with an AT but is a shame to give Up on what the TT and your ECM can doo for your bike full time.
