Well, I sprung for a Power Commander III USB for my '04 VFR about a week ago, installed it and man-o-live what a difference! I should mention that my scooter is completely stock, no aftermarket parts on the engine or exhaust. I was suffering the throttle chop as well as the 4.5-5k stumble, and I really wanted to do something about it. So from what I've picked up on from others on this site I went for the PC3usb in hopes of fixing the problem.
Once I got it I installed the PC3usb software on the computer, uploaded Cozye's map to it, installed the .99 cent Radio Shack resistors, and installed the PC3 on the bike. When I first fired it up it idled a little high, but it ran smooth so I figured everything was good and I'd just adjust it later after putting the bike back together. After reassembly, I fired it up again for a test ride and this time the idle was in the 1,200 rpm range so I left it alone, took it for a test spin and holy crap what a difference, it was like night and day! The bike runs perfectly throughout the whole range. No stumble, hardly any throttle chop. What a treat! It runs the way it should. Hey wait a minute, shouldn�t Honda should be paying for this?
Anyways, just want to give a shout out to Cozye, thanks for the map and the pic�s for making/installing the O2 eliminators, also to everyone else who�s offered input on the topic, very useful information in helping me make the decision. Cozye suggested that if someone should find his map useful if they could possibly make a donation to VFRD� well today I did just that, money well spent IMHO.
Oh and since the PC3usb install, my mileage is running fairly consistent at 44mpg. I know, probably not cranking on it enough eh?
The whole project was sweet easy success! Thanks again guys.
