Ok....check this out. These engine's have only one injector....correct? If it has only one injector, how can the ECM stop fuel from getting to the rear cylinder? I know it can stop spark, or mess with the timeing, or change the f/a ratio to manage the heat issues, but I just cant see how the ECM could stop the delivery of fuel to one cylinder and keep it going to the other, unless there is some sort of butterfly or trap door inside the intake tract that will shut/open to stop the f/a mix from getting to the rear cylender.....????
My stock 03 Heritage Softail, stock 05 EGlide Classic and my current 06 Ultra all came with an engine heat management mode built in to the ECM, no download necessary. It freaked me out the first time my 03 went into heat management, I thought I was blowing the engine up but was stuck in bad traffic for a couple of miles with no place to pull off. Later,I read what it was doing in my owners manual and thought cool, it was acting exactly like it was supposed to.
Lastyear at Bike Week, I got stuckin about 3 miles of walking speed traffic on the way to the cabbage patch. My Ultra wentinto heat management mode and I watched my oil temp gauge. The oil never went above 230 degrees, exactly what HD says is operating temperature. I can't imagine a big air cooled twin running the air fuel ratios they have totoday not having a heat management mode.
Does anyoneknow why this isn't stock on the 07 and 08 like it was earlier 88's? The 96 is supposed to run even hotter than the 88.
Had heat management turned on, not parade DL. According to the MOCO, all it does is shutdown the rear cylinder spark and fuel every one out of 7 cylinderstrokes at idle. Can't tell the difference. Does not seem to make it any cooler is S. FL. Had the header pipes ceramic coated which helped a lot. Installed Kuryakin heat deflectors which did not help at all. Just made the heat cook my thigh at a different place.
'07 FLHTCU.
Later 08s have the ability to able or disable the heat management function already installed. \\;\\\\\\;\\\\\\\\\\\\\\;\\\\\\\\\\ \\\\\\\\\\\\\\\\\\\\;I forget the sequence for abling and disabling but it is in the manual. I was stuck in a traffic jam in Portland, Oregon \\;\\\\\\;and it kicked in. \\;\\\\\\;\\\\\\\\\\\\\\;\\\\\\\\\\\\\\\\\ \\\\\\\\\\\\\; Idled rough but definitely helped the old leg. \\;\\\\\\;\\\\\\\\\\\\\\;\\\\\\\\\\\\\\\\ \\\\\\\\\\\\\\; Soon as throttle was applied it kicked out.
