Frustrated Bike running Erratically

Bike is running erratic. Chugging ,burping . 2011 Roadie,TTS tuner ,Naess Big Sucker 63k miles. Ran great until last week coming home 100 miles away pulled off road to fill up and wouldn't idle ,had to keep RPMs high.
Made it home running rough. Pulled code PO132,PO134,PO152,PO1353,PO1356. All oxygen sensors codes. Erased and ran bike, they did not come back.
Rode the bucking bronc again and pulled PO132,PO152. Changed sensors and no change.
Not bad fuel ,my wife filled at same hose before and after.
Any ideas ?
I changed plugs checked coil and wires and connections. Took it to an indy and he messed with my TTS and tried a map off their site and still does the same. He thought it lost the tune. I don't think that's the problem.

Can you isolate it to one cylinder or the other or is it both?

If the bike smooths out when you bring up the rpms and you changed the plugs sounds like a bad injector dumping gas, check those connections make sure there plugged in all the way.

When all else fails, hell there is always beer!

Both and smells like raw gas.
Pulled a new code PO113 ( voltage open high). This is new.

It was mentioned above to try removing the piggy back tuner, that is certainly a possibility as to the source of your issues. Sounds like an issue with the reference voltage in the sensor circuit.

Section 6.7 of the manual will walk your through the diagnostic procedure. But you'll need to run through it sans tuner.

You might try cleaning and re-seating the ecm connections. Then just for grins check your running battery voltage.

Yeah. Pull the tuner and see how it goes. I had pretty much the same issue on the way home from Sturgis a couple of years ago. It would run OK at higher RPM's on the highway but as soon as I slowed down it would buck and chuck and low speed and wouldn't idle. Pulled the tuner in Ohio and it was fine. Made the rest of the trip back with no issues, keeping the speeds low since it was running a little lean without the tuner.

Anyhoo. I found that the issue was a little crack in the insulation on one of the wires that goes from the tuner (Fuel Moto Micro EFI) to the fuel injector. It must have been grounding off the underside of the tank or throttle body mount. Fixed it up and it ran like a top again.

Not saying that yours is the exact same problem but the symptoms are very similar, especially that voltage open code.

A couple months back, I was speaking with Mark of Oasis Cycles in Brandon, MS,,, Oasis Owns / Operates probably the Largest Tuning School in the U.S.,,, a World Class Facility... Oasis specializes in Techno Research Products but has Tuned / used them all...

When I asked about "loosing" / "degrading" Tunes (with Flash Type Tuners)??
"I hear that all the time,,, it's total "bunk",,, the Tunes don't change,,, you need to find and fix the real problem..."

"I've read dozens of books about heros and crooks, and learned much from both of their styles"
