PCIII Closed Throttle Values
I know this topic has been discussed, but I have yet to see what values people have when setting the closed throttle position on their PCIII. The reason why I am posting this thread is that on Friday, I took the day off to spend the day riding. Well, it was around 32 degrees when I started up the bike. It idled fine at higher rpm's, but then as it started to warm up and go to a slower idle, it died, not once, not twice, but four times. I finally got on and pulled away and at the first light, same thing. Next light, same thing. The rest of my day went fine, but my stops were only for gas and lunch, and by that time, it was maybe 40 degrees or so.
So, yesterday, I hooked up the computer to the bike and PCIII. The closed throttle position was set at 3% instead of 0. So, I warmed up the bike for a few minutes, and when the idle slowed down, I reset the closed throttle position. Well, it continued to struggle idling and would spit and sputter, then die.
My questions are:
1. What rpm's should typical idle be?
2. What is a typical closed value position on the PCIII?
3. Is there another way to control how long the idle stays at a higher rpm?
4. What other things should I be looking for?
Attached are my recent values.

Actually, I posted the exact same thread on the Touring forum, and I think that is where you're reply is.

I am struggling with using the faceplate buttons. I thought you had to hold down the three buttons at the same time, then adjust which one you wanted, but I couldn't seem to get it to work. Either way, when I let it idle yesterday, it seemed to idle ok by adding some values in the first few values. But, the temperature here yesterday was in the 50's, so not sure yet.

Yup. You just hold all three buttons down simultaneously, but you have to do it inside of 5 seconds of starting your bike. Then walk the button of the range you want, either up (for longer duration) or down for lesser duration.
If you fail to make an input in a certain number for a few seconds or so, it will bump you out of this 'adjustment' mode, and leave you with the last input setting you made. At this point, if you're not done, you'll have to start the whole procedure all over again.
When you're bumping these ranges up or down manually, it won't matter if your bike is warmed up or not. It does matter that you evaluate the result of these changes with the bike at operating temp. though.
I usually bring my bike up to temp. beforehand so I can hear any idle changes as I'm messing with the buttons. Right away I know if the bike starts stumbling or running rough.
Just remember you are moving the numbers in both cylinder tables in the manual mode using the buttons.
