Documentation please.

I have never read ANYwhere that claims it is to prevent engine overheating.
If it was truly a tool to save the engine, we would not have the option to shut it off...

It only works at idle, and the engine gets hotter when it is NOT at idle. i.e., low speed under load..
Idle and stopped, however, is when the rider notices the heat, and that is when the EITMS activates.

If I'm wrong, I'm ok with that. Somebody show me where I'm wrong, and I'll buy the first round when we get to share some miles.

I leave mine disabled also. I live in Phoenix area. In fact, about a week ago I decided to enable it just to see how I liked it. The bike stalled at a stoplight when it turned green. Made me look like a newb who didn't know how to use the clutch. Then started thinking about it and that could be a dangerous situation... I'll leave it off, I'm not worried about the heat.

Maybe if I get stuck in traffic I might turn it on then, but thats about it.

[QUOTE=SafetyMan;13218894]It was designed for rider comfort, and beginning in 2014, the parameters changed for it to come on at or above 80°F AAT.

Just wondering(and i've heard this from other ppl)were you get the AAT input from.
The AAT sensor isn't even in the EFI Schematic.

To improve rider comfort on all stock Touring model motorcycles,
an optional heat management system (EITMS) may be
enabled. After being enabled, the heat management system
improves rider comfort by turning off the rear cylinder fuel
injector when all of the following conditions exist:
• High engine temperature.
• Engine at idle speed.
• Low or no vehicle speed.
• Clutch lever pulled in or transmission in neutral.
There is a four minute delay after startup before EITMS will
engage. As the engine maintains idle speed, the rear cylinder
functions as an "air pump," helping to cool the engine. This
continues until one of the above listed conditions is no longer
met, then the rear cylinder fires normally again.

I leave mine enabled. It has engaged frequently on hot days. All it takes is a quick twist of the throttle to disengage before moving forward.

Prior to 2014, it was activated by Engine temperature, and your information above is correct.

Beginning in 2014, it went to AAT. I do not recall where I read the 80° from now, but I can tell you that at 79° AAT reading, it does not activate, at 81°, it does.

From the 2014 Owner's Manual:

Quote:

Enabled: The EITMS engine cooling feature automatically activates whenever the vehicle comes to a complete stop and is idling during elevated temperature conditions. When the feature is enabled, it may not activate under cool riding conditions.

also, just because i know how some people are on this site, and your quote doesn't specifically state 'ambient air' only elevated temps (could be engine?) i cut and pasted this from the 2015 owner's manual.....
