EITMS - Engine Idle Temperature Management System
It is getting warm here in So. Cal. I have had the EITMS activate a couple days so far.
Observations - It works quicker/better than on my 2009. It is tied to the outside temp AND the internal temp on the motor (i think).
It was 91+ at lunch, when i first started the bike it did not activate but automatically did so at red lights after a mile or so of warming up.
I can definitely hear the difference. That is one big thumper at activation.
You can also see when it activates by pressing the "other side" of the right blinker.
Pic one shows enabled and pic 2 shows active.
I guess it is a good thing. It still throws me back to fouled plugs when i was younger. That was never a good thing as fuel was still being delivered to the cylinder....

I've used the info screen to show when it was enabled or disabled, but I didn't know it would show when it is actually active. Pretty cool. I'll have to watch for that.
I know what you mean about taking their word for it that EITMS is a good thing. Luckily they turn off the fuel injector when EITMS kicks in so we're not soaking plugs, but I keep remembering all the problems GM had with their 8-6-4 experiment. Multi-displacement is old news nowdays, but it still seems weird to shut down a cylinder in a running engine.

No, it uses an ambient temp sensor, but not until the engine has been running for at least 4 minutes.

I used Jason's fans on my '07. Worked well. If your EITMS hasn't activated on your '14 then either you have the EITMS disabled or it hasn't been over 80 degrees F yet while you were stopped at idle. The fans have NO EFFECT on EITMS operation on 2014 touring models.
Let me correct myself. I just reread Service Bulletin M1351 Some '14s do use engine temp, some use ambient temp. See the attached exerpt.

Road Kings and cop bikes use engine temp, all others use ambient air temp of 80 after engine has been running 4 minutes.
Fans will not change the EITMS on those, unless you re-direct the hot air from the fans to the AAT sensor, then it could come on when it is below 80...

•Touring (except FLHR, FLHRC, FLHRCVO, FLHRSE) and FLHTCUTG:
AAT sensor exceeds 80°F (27°C).
•FLHR, FLHRC, FLHRCVO, FLHP and FLHTP: ET sensor exceeds 288°F
Not sure but According to that bulletin the FLHTCU is not excepted,,,,, I better check to see if it's activated.

Getting hot here as well in Southern France. I have yet to see the EITMS kick in on the new wet head CVO, even in stop and go traffic. Also my legs are not burning anymore compared to my 2010 Ltd (with wards fans). Great job from Harley on the subject, and you visually hardly notice the change.
