09 SG.....nicely said !!!...

 

I believe only the '08-09 electronic throttle touring bikes have the potential problem.

 

Wish I knew this yesterday I ordered one

 

Don't worry...you made the right choice. It'll be fine. Many other PCV's in use with no issues.

 

To what i understand and just trying to help.. prior 2008, the cylinder cutoff can be done by holding throttle back few seconds and looking at the cruise light. If cruise light is green, then its activates, if it red, then its off..

prior 2008 which i think only late 2007's had the EITMS option, it could only be turned on or off by the HD dealer. This is i think due to the 2008+ have the Throttle by wire and no more cables.... please correct me if im wrong.

I can see how a stall can be a problem in parade mode when waiting for a light to turn from red to green and some dum A$$ can nail u in the back. I would suggest to disable it till a resolution is found.. im sure there is one. gotta be just a software upgrade...i have a 2008 and i'm curious of outcome as we all are.
Ride safe..

 

For any that have felt a stumble (or stalled) when accelerating while in heat management mode...

Give a quick blip to the throttle and then accelerate normally. This quick blip will be enough to restart the rear cylinder and you will be able to take off without delay.

This method worked for me even when I had autotune on in the 0% column.

Like I said, I never intended to report this on the forum...as my situation was completely self induced by not folowing the guidance for autotune. If you decide to run autotune, don't input values for the 0% column and you won't have this problem.

However, this method should work for anyone that has a problem with EITMS on their scoot with the PCV.

By the way...my EITMS works just fine now that I have 0's in the 0% column under the target AFR's in the autotune.

 

Ok guys, I came in early this morning and prepared a series of tests on our 09 bike. What I did was run the bike and datalogged the cyl head temp and made the bike go into heat management. With a cyl head temp of over 287 degrees the EITMS will drop the rear cylinder,and I was replicating stop and go traffic and started and stopped the bike 30-40 times. I could clearly hear and feel the rear cylinder come in as soon as I started moving with both the PC-V installed and unplugged. During these tests cyl head temp was in 300 degrees range which would be considered extreme and not likely under normal riding conditions. Of the 30-40 tests the bike did stall 3 times, 2 times with the Power Commander installed and once without and all three times it stalled while starting off using the same technique which was simply easing out the clutch without throttle. While simply easing out the clutch to start moving without throttle works under normal conditions it simply does not work well when the bike is in heat management. There are a number of thing coming into play when the engine gets this hot, in addition to EITMS the heat management makes adjustment to the AFR, ignition timing as well as the throttle blade. What must be done if the bike goes into heat management if EITMS is activated and cyl head temp is over 287 is to make sure that when the bike is sitting stationary that you open the throttle slightly before you let the clutch out to get moving as when the engine gets above 1200 RPM's the rear cylinder comes back in. Another technique is to simply blip the throttle before you let the clutch out which will activate the rear cylinder. With that said we do not see a problem with the PC-V and EITMS at this point and will get with Dynojet today for further discussion. If anyone has any questions on this feel free to contact me at 877-729-4754

 

And there we are, give her a little gas to wake her up before letting the clutch out.
Sounds logical to me. Just like 09streetglider said above.

Thanks Jamie.

 

Jamie - would this hold true also for 2008 model with EITMS activated ?

 

I have a new 2009 ultra and have noticed it go into back cylinder cut off mode a few times. I feel it idle rougher when its off, it smells different when wind blows exhaust back toward me. the thing I really dont like at it has done this quite a few times on me is that then I start to go the bike sputters, chugs ,and just wont run right and eventually cleans it self out after about 1000 feet. I have not added anything to mine and is completely stock. So I wonder if mine is doing the same thing as the guy who started the post and mine is still stock. I would luv to buy a pvc for mine and probably leave it off or just enable it when I know I am in slow traffic. all I need is money, I took one hell of a gamble and bought mine in sept 08 ,traded mine and the wifes bike in in it. they closed the factory where I work and sent the jobs to mexico, how many cars are they gonna buy for the 4 bucks and hour they getting paid. hope I have a job at fridays interview. so far the canadian bike price has risen 4300 bucks and is still 10% behind the real exchange rate. I have read all the posts on pcv from jamie and really want to get one , for now I just keep reading and learning and hope I get a job soon.
