My Ultra Classic has had the EITMS engage as low as 70 degrees on the info page. Each time it has been after a lot of hard highway riding, then a sudden stop at a light or in traffic.
I can only comment on my bike. The EITMS has never become ACTIVE until the Information screen showed a temp of 81*. On a warm day, after the engine had run for the minimum of 4 minutes and the information screen showed a temp of 81 or above, the EITMS would activate at every stop. If the info screen showed 80*, the bike could sit there and idle all day and the EITMS would not become active. One time on a cooler than 81* day I took the AAT sensor and placed it on the top of the rocker box. As soon as the info screen showed 81* the EITMS became active.

^^^^^^THAT has been my exact experience with the ETMS on my 2014 Limited.
I leave it on all the time and it only has activated when the info screen showed 81deg.
