Well, on my way to work this morning, it seems to have solved it. I did the fix in the garage this morning, and it was simple. Easy as Pi. ignition switch on, run switch on, twist forward and hold until cruise light comes on either green or yellow. Green=on, yellow=off. Thanks Hawg

Now that you know what was causing the idle to be different than what you're used to, you can decide if you want to engage or disengage EITMS. It's ONLY purpose is rider comfort (specifically stated by HD), and it does help reduce the heat around legs when idling. It will only come on when ambient temperature is greater than 80F and speed is less than 2 mph, and throttle position is idle.

Yeah, I don’t think having the rear cylinder stop firing the few seconds I’m at a stop sign or a traffic light would make a difference in the heat felt on my legs. I have lower fairings and keep the air diverted toward the fins, so it is getting adequate cooling during riding. I like the “normal” idle now. Thanks guys !!!

Yeah, I have an '18 FLHTK and just leave it on. Some folks hate the 1250 rpm single cylinder mode of EITMS but you get used to it. It's there moreso to act as an air pump to prevent excessive heat build up when stopped; like a parade mode. You can disable when stopped and running with the throttle trick, too. On my display I pull up the info screen to see status of EITMS (for us radio/nav unit guys) and you can watch it change from enable/disable as you change it, plus active when it's running on single mode. It sounds goofy, but personally, I'd rather leave on something that's designed to mitigate heat and protect the bike. These things already run a bit on the hot side. Just an opinion of mine. I don't recall reading anything saying it's rider comfort...where'd they state that info?

yeah, this is all it says in the OMs...what the heck does idling have to do with "enable or disable EITMS to complement their riding style"...lol

The Engine Idle Temperature Management System (EITMS) can provide limited cooling of the rear cylinder for riders who frequently find themselves in prolonged idle conditions or traffic congestion. Riders can enable or disable EITMS to complement their riding style.

Ah. Well, I'm not picky on the idle though I'll be posting on it not working properly in the future anyway. Saw some M8 cooling issue post that is my exact issue (what finally brought me on board with the forum) and it's one of the weird issues I've seen. I understand the limited cooling function; moving a little air through a cylinder isn't going to do too much. Good looking out.

Edit: it was a '14 Rushmore bike post that is VERY similar to what my '18 is doing. :/

Well I just learned something, I was not aware of this "feature". Have not experienced any weird idling so went and checked my bike and it is disengaged. I plan to keep it this way. Just curious if you install a cam with a lope (or what we now call a lope) what does the EITMS do to the idle?
