Part of what causes EITMS to activate is engine temperature, but also ambient temperature. I'm not sure about a 2010 touring model year bike, but on the 2017 and later touring bikes with a radio the ambient temperature value can be changed. If that applies to the 2010 models, them perhaps the value was inadvertently set to a lower value.
Also, EITMS is primarily for the passengers benefit in reducing heat. "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."
EITMS will turn off the rear cylinder fuel injector when all of the following preset parameters are met:
Throttle position is at idle
Motorcycle speed is under 1.2 mph (2 km/h)
Engine speed is under 1200 RPM
Engine Temperature (ET) sensor input reading is above preset level
Ambient Air Temperature (AAT) sensor reading is above preset level (radio equipped models only)
Thanks Paul, I understand the theory behind the eitms just questioning it’s activation when it shouldn’t be. As far as the power vision there does not seem to be a setting parameter related to ambient air temp on my 2010. I’ll see what the Dyno guy says next week.
thank you for the input.
Any update? Did the shop find any issues with their tune?
In a word, no. They put it back on the dyno and rechecked all their parameters and said the AFR is exactly where it needs to be throughout the rpm range.
They adjusted the parameters of the eitms so it enables later. (Not a fix, just activates 10 degrees later)
As said before the bike runs really well for the upgrades it has. It got 86hp 101tq which is in-line with its upgrades.
The tuner is well known and trusted and I have to give them the benefit of the doubt.
my only real concern was the eitms enabled more frequently than before the tune.
having said that the one thing I did different was prior to the cam swap I changed to Lucas “Dino” oil. (Didn’t want to run synthetic post upgrade of cams,lifters,bearings etc.)
Not sure but could it be possible that the Dino oil contributed to my heat issue?? Always used synthetic prior.
Changing back to synthetic soon so will see.
Not too worried.
As a follow up I checked the VE tables in the PV between the original tune and the retune. There was very slight changes made , plus/minus 0.1 to 0.2 .
Heres the tables if anyone with knowledge wants to comment. (Just numbers to me)

Can you post up screen shots of your (front and rear cylinder) timing and air fuel ratio tables... Also have you been monitoring your engine temps to see when the EITMS activated? And if you could refresh the engine mods.. thanks..
