The instructions are in your manual and may vary from model to model and year to year. I know for some 07's & 08's the dealer has to activate it. For my 09 FLHTCU all I have to do is without starting the engine but the ignition and kill switch "on" roll the throttle fwd and hold for 3 to 5 seconds. The Cruise Control indicator on the dash will either light up red or green. If red it's "NOT" activated. To activate let go of throttle and then roll it fwd again for 3 to 5 seconds. Cruise Control indicator on dash will now display green. This means it is now activated. Let go of the throttle and there is nothing you need to do as it will work it's magic until you deactivate it.
The EITMS system doesn't actually shut the rear cylinder down; it causes 70% less fuel to be delivered to the cylinder so that one cylinder runs a little cooler in a high temperature situation, such as being stuck in stop and go traffic on a very hot day.
This is the first I've heard that the ECM keeps adding fuel (30%?) to the cylinder that is shut off. I can't imagine this being done. What happens to the raw fuel that's not being burned? Seems like there'd be a big boom as soon as it got to the catalytic converter? My understanding was the fuel was shut off and the cylinder just pumped air?
On 07s and early 08s it has to be enabled or disabled by the dealer
there was a campaign to do this ONCE at no charge. On later 08s and everything since with TBW (Throttle By Wire) it is turned on or off by following the instructions in your owners manual.
With the bike stopped running or just in the run position roll the throttle forward and hold it, watch for the cruise light to flash and release the throttle.
If it flashed red you just disabled the EITMS
If it flashed green you just enabled the EITMS
It is only active at idle and as soon as you increase the RPM it goes back to normal.
On our 08 FXDSE2 it is enabled. Since that bike has regular throttle cables I assume that it can't be changed by the rider. But that's a question for the SE section of this forum ;-)

Keep adding fuel, even 30% doesn't make any sense to me either. I've always assumed that under EITMS the rear cylinder becomes an air pump, nothing else.
Your bike must be at idle with the engine oil temp above 262 degrees for EITMS to kick in. It's dealer enabled during initial bike set up on 09 and later.

I was told at a local H-D dealership that the EITMS system reduces the amount of fuel being delivered to the rear cylinder by 70%. I can't personally confirm that this is in fact what happens in a high temp situation but this is what I was told by an H-D employee I presumed to be an expert. Perhaps someone on the forum can give us the definitive scoop.
Wow, I learn something new every day. Had to go out to the garage and test it on my 10 SG. Yup, roll throttle forward for a few seconds and the cruise light went green.
