display
Went Christmas shopping, got caught in traffic jam, waited for stopped school bus, had to circle to find a parking spot at the mall. I figured it was getting hot so I let it idle while I took the helmet off & saw this. 28 degrees below the ambient air temp threshold and the EITMS kicked in. The bike is 8 months old with 13,200 miles, totally stock and runs great.
I wish they would display engine temperature, their is a sensor in the motor that is what the ecm uses, that way if you were stuck in traffic jamb you could at least shut your bike off .

The ecm map contains all the parameters that make everything on the bike work including the EITMS. When HD updates any of these parameters it is done in the ecu mapping. When you have a tuner like the SEPST or PV they release updated base maps with the updated data in them. For my bike I'm using the Stage One SEPST map as my base map and then I autotune and make manual changes to that map. Or if you have dyno tuned your bike they start with a base map and then tune it. There are many parameters in that base map that we can not see or change and when they release an updated map you never truly know what they have changed if it's not viewable. With the SEPST you copy all the tuned cells like VE tables from your map to the updated map and then load it into the bike. This way you get the new data and retain the tuning you have done on the map.

That is a good pic, I also switch back and forth two that screen to see if it is working , I just get nervous when I see the 10 psi oil pressure, but that is another thread and I have been told as long as the red oil light on the dash does not come on you are good,

Temp
Wonder if my EITMS will still work even though for some reason my bike temp displays --. I replaced the temp sensor on the front right but still no luck. I guess I'll find out if it still works over the summer. I'll have to take it in before the 2 years are up but I hate leaving my bike and having others work on it...but since I have ABS that is one think I know I'll have to let Harley work on (bleed brakes). Wonder if flashing with FP3 affected my temp display to not work...
But anyway this brings me to an Idea I had reading this post. Since no one the dealers the harley manual , Bulletins really knows or they all contradict themselves as to when the EITMS actually is supposed to come on, and the AATS sensor is easy to get to someone could unplug it drive their bike till it gets hot , pull over in a parking lot (so they are safe) switch to that screen and let it idle and see if it comes on. If it does then it has nothing to do with outside air temp, and I don't think that by disconnecting the sensor it would hurt anything cause isn't that sensor only for displaying air temp, I mean the engine has a air temp sensor built in to the throttle body that the computer uses for air temp and one in the head to manage the fuel. ?
Of course at 80 degrees + it would come on sooner cause the motor would get hotter faster.
Boy I really wish they could have the dash display engine temperature.
Holy cow I just had another thought, if you could turn it off, is it really that important to the motor, will it come on if the motor gets to hot, or like I think just rider comfort?

I know the base map for my FHLX has changed at least twice. When I plug in my SEPST it will tell you if the base map is out of date and needs to be updated. Twice I have had to copy all my tuning data over to the new base map and load it. Of course you can't see the changes that were made in the base map because the changes are hidden changes. It could be that HD has changed the parameters and those of us that have updated our base maps have the new parameters and those that are stock or haven't updated the base map have the old settings.

I can only speak about my experiences with my bike. My EITMS goes Active when the bike is at idle, after it has run for at least 4 minutes, and the temp display is at 81 or higher. On a cooler day I placed the temp sensor on top of a hot rocker box to 'fool' the sensor as to the air temp. The EITMS activated at 81. If my display shows 80, the EITMS does not activate.

Webo, thanks!
Joe Nash, I doubt that we can turn off EITMS activation triggered by engine temp, but that is a guess. As per H-D it does not happen, contrary to what my photo shows.

No this wouldn't work with the factory map. When you install the SEPST you load a base map, when that map is updated by HD and sent out the SEPST updates that map with a new revision. So the next time you connect the lap top to the SEPST server it will tell you if the map you are using is out of date and has been updated. SI it would only work after their map is installed.

Eitms
So We are just turning it on sooner if we select it to be enabled on our screen that displays the status, cause it will come on at a lower air temp not engine temp? and also if it is not enabled on out display it would eventually come on if the engine got too hot? ??? that what I get from what you say???

We know we can turn off the ambient air activation (80 degrees) but I doubt (and I'm guessing!) we can turn off activation triggered by high engine temperature.
My original question has been answered in part:
The engine temperature sensor does indeed signal the EITMS to activate (at least on my bike, see my photo), but at what temperature ?
My original question has been answered in part:
Question: Is there a temperature threshold that activates the EITMS? If so, what temp on what part?
