i have a FZS 600 and a GSXR 750, so i know the Power Commander is not applicable to the carb'd FZs600 but i have been reading about them and why you might want one...there are lots of ones on ebay for a GSXr 750 of my year so its got my interest, i am not sure why :\
I read a lot about when you change the components on a bike such as to alter intake and exhaust you change the air to fuel ratio, and can cause engines to run lean and hot, then burn things..
Anyone have any comments on power commanders, if they are needed, etc?

Do a search on my User Name and Power Commander and you'll find quite a few posts from me about them (personally I'm all in favour as mine is good for, at the very least, fixing the hole in the power curve caused by Yamaha doing a Volkswagen on the fuel injection system to improve the emissions when they're tested!)
Ive just fitted one on my gsxr6. Dyno doesnt lie  .
I run a tri oval and k&n and have more power from 7-14500. Peak power is now 109 compared to 98, unmapped. Fuelling is also spot on. Think of it as a jetting kit for a FI bike
The problem with socialism is that sooner or later you run out of other people's money!
I have discovered my Street Triple has a PC-V fitted, and not being familiar with FI bikes, I have been wondering much the same myself; what does it all mean?! :lol Am I about to be dragged into the 21st century? :eek
these days ignition/fuelling is mapped for various scenarios, throttle position, air temp, revs, gear etc. so hopefully when you twist the throttle, the bike responds in the best way possible, except the politicians have decided that the combustion engine is EVIL and must conform to strict noise and emission regs, so the standard map is a compromise.
enter the power commander, it allows someone to interfere with the standard compromised map and install a far more efficient/powerful/linear set of instructions.
and being full of electronic trickery, it can remap for every 500rpm (pc3) or 250 (pcv), then you can add quickshifters and all sorts of other bits and bobs.
HTH

You can download maps for them from the Dynojet website which are matched to different exhausts and air filters which should improve the engine response and boost bhp and torque.
Or do what I did eventually, and others on here have done, and get it on a dyno and get a custom fuel map made to suit your bike, well worth the money and time. My FZ1 puts out 143bhp at the back wheel now even with a standard can on, I have now fitted an Akrapovic can and need to get it back on the dyno to get another fuel map done to suit and should get a few more bhp over the standard can.
i actually have a PC3USB i got off ebay, and intend to fit on my GSXR, just looking into it now, have a map that matches my bike and Akapovic can as well, was just wanting to see what ppl's thought.
am also waiting to see what insurance say about it, they are going to get back to me!
update, insurance WILL let me put a PCIII on it, 40 quid more....i don't see why but what can you do!
So fitted it tonight, not too hard, dropped a bolt into the chassis are so going fishing in the light but seems to run fine with it plugged up, sounds a little richer, unless thats just in my head.
Shall find out when it dries out around here what is feels like compared to without.

It depends on the insurer. Some consider it an add-on to increase the power, so up the premium, others will accept it if you're only using it to improve the fuelling and smooth out the power curve.

Don't think I'd bother personally - you could have just claimed you didn't know! (obviously a bit difficult if you'd rung up about it though :lol )
i know, but i am a worrier like that so for my peace of mind it had to be declared :lol
Hedgetrimmer, I am told that Power Commanders are a waste of money on Triumphs as you can download free software from the web and use an ODBC II cable with your laptop to change the engine mapping yourself using the socket under the seat.
Another ex-Fazer rider that is a foccer again

I really have no idea. The bike has a non-standard can which I want to replace with a different one, but other than that, I won't be doing much. It ran really sweet on the test ride but haven't had a chance to get out on it since. If it runs ok with the can I want, I doubt I'll need to touch anything else anyway?
update, so fitted and been out tonight, noticeable difference in the mid range, very nice little upgrade, i thought it could shift previously but with this it feels even more pokey :lol
Street triples upto 2013 models can be mapped with Tune ECU and a cheap cable. 2013> they locked the ECU down so you can't just drop a map on it, so you need PCV. I think.

There's no replacement for displacement
So, can a power commander improve fuel economy on my FI CBF1000 or even be switchable between power and economy modes?
Those are my principles...if you don't like them I have others.
the PC5 can store 3(?) different maps, but i would imagine once you have the optimum set up, you wouldn't need to change. i would have thought fitting the R ecu (150hp)would have been your first thing to do!

Damm - now there's a thought. Missed that completely, cheers fella... i'm off digging

I have a switch on my PCIII to swap between two maps, the basic one which just smooths out the fuelling and the "fun" one which boosts the mid-range power, but at the cost of about 25% of fuel efficiency.
The only time I've really used the latter is when I was doing a Skills Day at Thruxton...
