Hi folks,
I put a Yoshimura rear pipe and downtube on my RR a couple of weeks ago, and since then it feels like its a lot less smooth on the power delivery and through the rev range. Do i need to have it chipped or something to re-calibrate the fuelling? if so, where would I get such a thing and how easy are they to fit?
it sounds ace, by the way

injection i guess. its an 04 cbr 600 rr if that helps.
Power commander and either a pre-made downloadable map or custom map done on a dyno is probably the best way to do this.I'm running a power commander v3 usb with o2 sensor bypass on my 03 CBR600F with the std exhaust map off their website. This leans it back as its overfuelled std giving it some extra 20 miles per tank on a long run. Additionally it accelerates somewhat better too.
how and where did you get all this? i just looked on their website and it seems to hugely expensive and hugely confusing.
I can see that they have a map for my bike that I can download (except its for a full system, and mine is only from the mainfold pipes back, which im sure is significant) and assume that I need a Power commander thingy to tell the bike to do that, but have no idea how tricky it would be to fit one etc.
is the alternative to go to a bike place and get them to rechip/ rewrite the ecu?

almost everyone uses a power commander rather than rechipping the ECU on bikes, its just the way it seems to be done.
they are easy to fit honestly. it'll come with all the info you need. basicly you unplug the multiplug between the ECU & the bike, plug the ends into the plugs on the power commander and thats it. apart from connecting the power commanders earth lead to the neg battery terminal.
when you order the power commander they should ask what mods you've got & will preload it with the best map for your bike. so it'll be fine to use like that.
a dyno run and setup would improve it, all the standard maps are a bit rich to make sure they dont do any damage.

i guess from themselves is the simplest way and they'll know the best map for you. all their approved centers are listed on their website, so if you prefer you can find somewhere localish to fit it & maybe dyno it. always worth shopping about incase someone is doing deals after all.
when i had my 14 dyno mapped it was £120, but i got it cheap as it was a club event. i think its £150 normally. i've definately got more power, more throttle response, a smoother engine with a wider power band and better mpg from it though. so i'd say a dyno is the way to go when you get chance.
ETA: i cant tell you where my power commander came from as it was on the bike when i got it.

both.
the PC will help will the running as it'll get the fueling closer to optimum than it currently is.
the fueling table in the PC is fully editable so with a bike on a dyno they can set up the fueling for all throttle openings/revs to optimise the fueling. a standard map is always slightly rich, as some bikes will run leaner than others so they have to err on the safe side of perfect.
editing the fueling table in the PC on a dyno is like having an older bike dynoed where they change the carb jets until its correct.

Right now you're interested I'll give you another tip on where to get power commanders. Don't buy the unit directly from them shop around!!! Also don't pay the UK price as you'll be seriously ripped off hence it appearing 'expensive'.
A number of people get them shipped over from the US from friendly powercommander dealers and being so small they pretty much all get in as low dollar value marked gifts to avoid import duty. Paying the US price you save loads.
My current bike was my best mates before hence me knowing all this, yes he got his shipped over from the states.
I'd suggest joining here CBR-Forum.org.uk if you've not already and reading up on how to get one and how it works etc. I'm obviously not going to repost details on here.

sorry to necropost this, but im just looking for power commanders on ebay now- could i just buy anyone of them and then download the relevant map for my bike, or do i have to buy a bike specific one?
are they bike specific because of the plug and fitting or just the map?
bike specific since the ECU plugs aren't a standard fit.are they bike specific because of the plug and fitting or just the map?
