Much wiser minds have commented on this than I and I assure you I know nothing compared to them. BUT some years ago I had what sounds like a similar problem with my ‘09. Erratic idle and would chugg chug on acceleration and sometimes would clear. Worse when hot or even just warmed up. We went through everything mentioned above and more, replaced map sensor, loaded various tunes, new spark plugs, even had the injectors ultrasonically cleaned. Nothing worked. As a last resort I put a new set of plug leads on. Bingo! It was perfect. If your coils are fine, it could be a leads. Just a thought.
I really think that's a possibility. Sadly I have limited tool part ect. Hopefully the shop will have something tomorrow 🤞

Okay the saga continues I got the bike back this morning. It is ridable somewhat when defined loosely. The shop told me I somehow had two maps and that were fighting each other. The problem is they loaded what I think is a stock map. So at cruise throttle rpms it lean surges and sometimes cough from the intake. I'm thinking of reloading my original tune file. But I really don't wanna screw things up worse. The tuner I. Seattle said that wasn't possible for that to happen also.

My anxiety is peaked and I'm not thinking clearly, I'm open to suggestions. The good news it's it doesn't sound like a parts issue.

I don't have much to offer at this point.

I remember back in the early days of computers, there would be unexplainable glitches, and someone from the finance department would call asking what is the problem, and when they could get back to work, and the head guy would respond, "There's a glutch on the tazmu, and we're working on it."

That's what the dealer told you.

I am speaking only from what happened to me when I was only about 300 miles from home and bike started running bad and had a miss.

Yes I could have fixed on the side of the road but I just rode at the speed limit and it ran fine.

But I knew what had happened so wasn't that concerned.

It was the spade terminals on the one coil had come loose and I knew it as had happened before it was a right pita to get it back on as I over crimped it but finally with the help of a screwdriver i forced back on and no trouble since.

Apologies for not responding phar2slo, it's been a crazy month.

So I think it turned out to be the TPS sensor. It would randomly freak out under heat vibration idk. Basically it would cause it to run crazy rich and die or not idle at all. I couldn't catch it in the act, until I got my bike back from Denver yesterday. It sat at the dealership while they seemingly poked at it with a stick perhaps... Anyway I got lucky and it finally threw a code. Tps voltage low. Luckily thanks to you guys I ordered a tps when this started. Swapped them out and now; lol tune ECU won't connect unless the ignition is off. So I can't adjust it properly. I ran the bike and it seams to work great. It idled hot for about 20min with no issues, hesitation, or idle problems.

I've contacted tune ECU about the problem hopefully they are better then the dealerships that gladly waisted my time and took my money. But does anyone have any ideas why it would connect only with the power off? I've used two cables, two phones and a laptop and I get the same red flashing "TPS light", as it's referred to in this forum. Slow flash and then pause.
I know you will ask the battery is new. I had my charger connected and a separate battery for good measure. The voltage never drops below 12.5 verified with a multimeter.

Tuneecu updated last nigh and everything seams to work perfectly. Lesson learned to anyone rocket TPS sensors are junk, be sure to have a few around.
