Any reason not to enable the rear cylinder cutoff?

ehans · #1 10-22-2009, 09:27 AM

I have an 09 Road King Classic and just turned 1,000 miles - had the initial service done. The rear cylinder cutoff feature came from the factory disabled and I figured I would leave it disabled through the break-in period. Winter is coming (if you can call it that in SoCal) so it probably wouldn't activate much right now, but thought I'd go ahead and enable it.

Any reason not to? I've heard about the smell when it kicks in - probably won't bother me. My main concern is engine longevity. I want whatever is best for the engine, and I'd think running cooler when sitting still would qualify. thanks.

??

Came from the factory disabled? Interesting.

I'm no MoCo technician, but having the EITMS enabled was definitely nice during Sturgis when I made my 1 trip down Lazelle street during the daytime with a bazillion cars/bikes/RV's.

That said, I wouldn't hesitate to enable personally.

I just leave it enabled all the time. Haven't heard any good reason to disable it.

Mine was disabled also when I took delivery. I enabled it and haven't messed with it since.

I leave mine enabled all the time and to date I have not had it kick on yet even in higher temperatures.

Mine has kicked in many times,and it helps.I haven't noticed a smell though,only difference is it is obviously running on one cylinder.Sound and vibration.

Mine has been enabled from day one...

It's interesting that the maps for the higher performance engines that come with the 2010 SuperTuner, have the EITMS turned off. If you look at the HO 113 and HO 110 maps with 58mmTB and larger injectors, they both have the EITMS turned off.

Anyone have a thought why engine maps for higher performance engines would have the temp manegement turned off? Could it be that since the maps are delivering far greater fuel (therefore running cooler), there's less of a need to turn one of the cylinders off?

If you're in So Cal. you have traffic I would leave it enabled, mine was also disabled from the factory, I leave it enabled

I can see having it disabled during the break-in period, but the only reason I could see keeping it disabled, would be if you're in a cold weather climate area.
