I've put this in here as it's more relevant to this area...
How did the power commander installation go? Did you have it dyno'd afterwards or did it work out of the box?
Ok, I bought the Power Commander second hand from expatmanxman (see a few posts down). I only got the unit but it's easy enough to download the mapping software and fitting instructions from the Dynojet site.
Fitting it turned out to be a bit of a palaver, for various reasons...
1) As I don't have a laptop I first had to find a way to install the map onto the unit from my desktop. You can do that by connecting it to the PC with a USB cable, but you also need a 9V battery and connector to power the unit. Fortunately I had both and managed to bodge a connection so I could load the map before I took the unit down to my shed where I keep the bike.
2) I was a bit puzzled at the completely different settings on the map I downloaded which said "Stock FZ6" and the one on the unit which said the same, then I re-read the previous thread and the instructions and I realised that the stock map which was on the unit when I'd bought it had been modified, but not the comments, so I put the Stock FZ6 map I'd downloaded onto it instead.
3) Fitting the unit turned out to be a major PITA! You're supposed to put it under the seat, but where they suggested it went is, on my bike, taken up with the alarm, fortunately I found that by taking everything out (tools, pliers for pulling nails out of tyre, spare headlamp bulb etc) there was just enough room to fit the unit and get everything back in place (just!!)
You also have to lift the tank (*why* don't Yamaha include a prop for it?!) fortunately I remembered that if you undo and remove the pivot bolt at the seat end of the tank and then undo the securing bolts at the front you can slide it back and then lift it without needing to remove the inner fairings too.
4) The next part, actually connecting it, is a serious fiddle!
You need to run the wires from the unit under the tank to a pair of connectors behind the throttle bodies through a narrow gap which took a lot of finessing to get all the bits through and then you need to actually identify and get *at* the connectors which are buried amongst lots of other wires in the loom.
There was about half an hour of looking, cursing, looking again, pushing things around, cursing, examining connectors, more cursing, trying to undo connectors, re-examining connectors and comparing them with the ones on the unit, finally figuring out how to get it hooked up and then *more* cursing as you try to get everything back in place!!
Incidentally I found it was easier if I removed the left side rear fairing that covers the fuses etc as it made it easier to see what I was doing and gave better access.
5) You then need to connect a wire to the negative side of the battery, but there are already two connectors on that on mine (Optimate and Heated Gloves) so I wasn't sure if another one would stop the battery bolt from securing properly, however I then found that I couldn't even *undo* the bolt as it was done up incredibly tightly and when I put more pressure on it, the metal started to strip.
Fortunately a few minutes with a multi-meter revealed that the bolt that secures the front of the tank would also give a negative connection, so I connected the wire to that instead
6) At this point I decided it would be better to check that it would actually work before I put everything back in place, so, with fingers crossed I pressed the starter and, fortunately, it fired up!
7) There was one slight problem when I put the tank back down because I must have kinked the fuel hose as I tried running it again and it started and then died, but a quick lift back up and moving things around solved the problem.
Then, finally, it was just a matter of putting everything back in place and after a spin around the block for a final check (I didn't want it dying on me out on the M271!), I took it out for a very enjoyable ride up the A32, along the Morestead Road and back along the A272 before returning on the A32 again.
Is there a setting that stops the annoying jump off a closed throttle? 
Well, with it installed and the map mentioned above, I've certainly not noticed that which is another plus point!
What I mostly noticed was that there wasn't that awful hole in the power curve around 5-6000 RPM, after a little experimentation I could go for an overtake in fourth gear and know that the power was going to come in smoothly rather than it bog down until the revs got over 6k and *then* pull, meaning I didn't have to sit in third gear on A Roads with the revs up waiting for an overtake chance or keep flicking up and down the gears any time I wanted to pass someone.
Frankly I consider it a very nice addition to the bike, the power is much more accessible and controllable and there's a bit more of it too
