power commander troubles?

not sure what's going on with my 919. Sometimes it idles fine then almost dies at part to mid throttle. Turn the key off, try it again and it's running perfect. Totally random, sometimes it does it 5 times in a day, sometimes not at all. What the hell? Don't think this has anything to do with it but it was about the same time I hooked up my electric vest, it's connected directly to the battery. It will do it without the vest plugged in.

Put the map back to stock setting for the bike and try it again. If it doesn't die, I bet the map is poopy.

is the ground for your electric vest straight to the negative battery terminal, as on the pc III ? if so, put 2 + 2 together.

Or remove the PCIII altogether and try it.

Basic rule number one: if you did something and something else goes wonky, what you did caused it! 999 times out of 1000. I suspect a slightly loose positive or negative connection at the battery, or a loosened ground lug to the frame. Forget playing with the maps -- if it ever works, that's not the problem.

agreed Rob: i used to be a dealership service manager (cages, not bikes) and a "come-back" customer always had me looking at "who was in there last, and why?"

especially with Hondas: it's almost ALWAYS the human, not the bike.

+1 on the loose connection somewhere. sometimes a loose wire will have good contact until vibrations from the engine change. This happened to me this year on the track bike took me a while but i finally figrued out that i one of the sensor connectors had loose female contacts. I hate when my females get loose.

ground connections are tight for vest and PC. I'll have to check all connections and wires next. I realize it's got to be something I did. My buddy says "f'n Hondas" I say it ain't Honda's fault, if I didn't touch it she'd still be running perfect. Thanks for the input. I'll see what I can find.

all connections and wires were good so I pulled out the PC111 and ran it on the stock computer and it runs fine now. Hope the PC111 just needs a re-programming.

Sounds like the PCIII needs a replacement.

i think many people fry PCIII's by botching something during install. i'm pretty sure i bought one of those botched PCIII's off ebay last year.

i'm buying a new one this winter; though there's only a smidgen of trouble i want to eliminate the PCIII as the source, and i may get a quickshifter too.

Mines going back to get checked.
When the #4 LED burnt out, or went out, the bike got sluggish at 1/4 throttle.
It wouldn't build power like it used too & took off weak from a stop.
Without it, the bike runs perfect. Except the surge/touchy throttle, was back.
It was only working good for about 6-8 months.
I noticed something had changed but kept riding it anyway.
When I finally did, pull the seat to check things out, is when I noticed the LED. It all kind of matched. The LED & the feedback from the bike.

mine was not botched but anyway I won't be one of those ebay dicks who sell something that's damaged or malfunctioning and claim it as good. I get it fixed or smash it with a hammer. I will consult the pros at Dynojet.
