Problems after Wide band Autotune install
I have a 2020 Road King with a PV3 tuner and Fuel Moto tune. I got the Wide Band Autotune kit from Dynojet, (which isn't exactly autotune, you log data and change the tune in the WinPep8 software). Anyway, after installing the kit, I have like 5 different codes and the check engine light is on. Bike runs fine, but it's not supposed to do that. All the codes are O2 related. I'm wondering if the fact that there are no longer anything plugged into the original O2 data ports, is that causing the codes? I plugged the old 12mm holes and I thought the Autotune kit was supposed to tell the ECM that there are wide band O2 sensors. Since the old O2 sensors are no longer plugged in, and the new 18mm ones plug into the module and then to the ECM port, there is nothing in the old plugs, I kind of feel like thats a problem. There is next to no information on the internet or Dynojets website on the kit for the PV3, so I'm kind of lost. I did send a request to Dynojet about it, but that could take a week to hear back from them. Any ideas?

Is your tune enabled for the wideband sensors and Autotune module? I'm guessing that's why your ECM doesn't recognize the widebands. You need an enabled tune for it to work. DynoJet or Fuel Moto can do that for you.

fuel moto isn't using the autotune module for the PV3 yet, as per Lucas. It's still pretty new, so they may be testing it before they support it, just my guess. I'll call them anyway, and hoping to hear from Dynojet, but rather Lucas help me, he's done all the tuning on my bikes.

I have a PV3 tuner on my 07.
My understanding on how this works is that you need to REPLACE the original O2 sensors w/ wideband versions, enable the software for wideband use, THEN run the autotune (logging and editing).

I replaced the 12mm with the wide band 18mm that came with the kit and plugged the 12mm holes. There are no instructions on how to enable the software.
