Did you turn the ignition on, or use the 9volt battery plug to suply some power to the PCIII and don't run the motor while uploading.

You can also check the part number and see if you have the good model.

Is the latest software installed on your computer?

I don't recall the exact error but I had a similar problem with mine when I first got it (used). The USB plug was very loose and I had to wiggle it "just right" for it to work.

A few months later it died and the engine would not rev over 3 or 4K.
PS. I plan to replace it with a Cobra FI2000R

i had it installed on the bike. i tryed it running and just with the key on.
im not sure about the software, it was not my computer that i was using. i guess ill try wigling the cable when i get a chance to mess with it angain and check the software version.

is the cobra controller better? or easyer to tune?

The Cobra is ~$100 cheaper, requires no computer and from my observations is more reliable. I'm not saying the Power Commanders fail often but they do fail. Over at the Sportster Forums the Cobra is very popular and I haven't seen a report of one failing yet. I will be replacing my busted PC with a Cobra before riding season starts.

Start with the simple stuff, make sure the earth is rock solid.

yep, it is. i put it directly on the battery - terminal

Ok, if the 9v battery you're using is anything less than minty fresh, this operation will fail to. To remove that problem, cut the 9v clip off of the battery adaptor, put some alligator clips on the end, and attach them directly to the battery. That'll ensure it gets a good strong voltage source (yes it's 12v, but the PCIII can deal with that no problem, you're actually plugging it into the 12v input pin on the 10 pin connector).

See how that goes.

havent done the 8v thing, i dont have the plug for that. i just plug in the cable while the key is on

 

[imdying]

Well that'd be what I'd try next, perhaps it doesn't like working correctly with the bike on. I've found my laptop won't communicate with the wide band commander if the WBC to LCD hub harness is plugged into the 10 pin connector, so nothing would surprise me.

im gonna keep messing with it for but for now i just bought a techilusion tfi for 76$ from motosport, they are on sale its the flying lead type but for the price i dont care. i was considering a fi2000 but the tfi looks better to me, the price was the deciding factor!
