2011+ Idle Adjustment?

So I seem to have nailed the electrical issue. Rusty underneath the negative terminal and it was loose, it looked great on top.

But I noticed on my test ride the idle is low when it heats up. I adjusted the TPS again since I played with the exhaust valve to clear the C46 error. (Those nuts have to be tightened or the stepper wraps the cables around itself, lol). It's slightly better, but still sitting at 1k when the frame sticker says 1200.

Checked the manual and it says the idle is digitally controlled and only adjustable with the SDS. Since I don't want to pay the hundreds for my dealer to look at it, and I don't want to pay the hundreds/thousands for the SDS tool... does anyone have any ideas?

(Or if someone knows a decent mechanic/dealer in the north Houston area? K's Motorsports wants $75 to just hook the tool up, another $60 an hour for idle adjustment with a minimum 2 hour charge, and they can get to it in March if I drop it off now. Their oil change "special" is $225 for supersports, plus oil filter if needed. Needless to say, I laughed and hung up.)

Id have someone flash the ECU and disable the ISC , then adjust the idle manually .

I thought about getting the Healtech box from time to time but have never had an issue that I really needed it. My K6 is still has the manual idle speed.

The price isn't hateful.

ISC. Had to look that one up, first I'd seen one. But I guess you'd need an electric valve to set idle digitally. I figured it just used the secondary throttle valves.

So it sounds like if I disable the ISC, I can just adjust it with the screws like you used to do? Huh. The knock off SDS tools from eBay and the like are cheaper than a reflash or reflash tool and I could just retune it. How legit are they though?

It does ECU reflashing or just inline stuff? I'll have to look it up.

I found the healtech box. Honestly it's only $20-30 more than the knock-offs, and about the same as a ECU reflash. I might just do that after I look some more into what all it can do.

Ran the piss out of it today to fully check the electrical issue. At enough throttle to make the front end light, but not a wheelie yet, it threw an FI light and lost power.

Pulled the code and it was C37. That's one of the secondary fuel injectors (don't have the manual on my phone so I can't say for sure which one). Would that cause idle issues? Not sure when they kick in.

Yes, C37 is the cylinder #2 (second from the left) secondary fuel injector.

I've read somewhere that they don't come in till about 5k, but maybe someone can confirm.

I don't see how this could affect idle unless it was dribbling when it should be closed. I don't think the ECM is smart enough to detect this.

From the service manual.

DETECTED CONDITION POSSIBLE CAUSE
Some failure exists in the fuel injector signal in a
high load, high revolution condition.
Injector circuit open or short
Injector malfunction
ECM malfunction

Yep, lifted the tank and that injector wasn't plugged all the way in. Probably from when I pulled the throttle body. There has to be a throttle position minimum too. This is the first time I saw it since it was the first time I felt in a position I could gun it. (Traffic, haven't ridden in 18+ months, etc)

Won't get a chance to ride tomorrow cause a storm is coming. I'll see how it's working on Wednesday.

Cold ride today, but I found a large parking lot and lit it up. No problems with the power wheelie.

Got the engine warm while I froze, and it seemed to drop the idle to 1200, hover for a second and then fall to 1000-1100. It never dipped below that.

Huh. New plugs maybe? They looked okay, but the 7500 mile service says to replace them. And that's in 500 miles. Replaced the air filter when I cleaned the wasp nests out of the bike. (It sat in a shed for 2 years). Oil is on the list. It looked clean when I got there, like he just changed it, so I wanted to see if there's anything in it. So far no sparkles, but I still want to dump the oil and check.

TPS is adjusted. Exhaust valve is adjusted, and I can disable it if someone thinks that's an issue.

Just trying to think of anything that might affect it before I drop $$$ on the ODB tool thing.
