What does the PCIII do when powered off and still connected?
My bike has a PCIII but I haven't even bothered playing with it since I bought the bike. I knew it wasn't tuned right but it was fine more or less for my needs so I just left it, knowing it was something I would get into eventually but I am a procrastinator so tomorrow didn't come until yesterday.
Generally I had a pretty bad bog around 3500 rpm which seems pretty standard from reading posts on here, and I would bog out at higher throttle, like I could bog it out in any gear by cracking the throttle open and it would limit my immediatly reachable top speed to about 150km/h that I could creep up to 175 ish if I was super delicate and the road was flat and straight. When I cracked the throttle and the engine would bog I could spell it was very very rich.
Last night I discovered that the PC wouldn't even power up, and I found that the negative power connector was just completely disconnected. When I connected it the unit still had no power. IO imagine a blown fuse or the positive is also disconnected somewhere but this was just a short window of time and I didn't have a wiring diagram with me so I tested simply unplugging it and it seemed to clear up pretty much all the problems I was having. I haven't had it out on open highway to really test it yet, but I think I have already noticed a pretty big difference.
So I know I am probably not ideally tuned right now, I have cut down yoshi bolt ons and a high flow filter, but it's a lot better for the moment. I'll figure it out some time, but why does the PC cause problems when it's powered down? Is it interrupting or sinking a signal even when powered off?
