Yeah, go get a power commander :P seriously. Aftermarket pipe + power commander = works out that flat spot around 4-4.5
Blades have that god-damned flat spot, the '92 cbr sits in it at 100km/h, fucken shocking. 900cc of stonking power (for a honda) and you gotta down shift to pass. The solution? exactly what you have done. Aftermarket pipe. But there is another very crucial part, oh yes, the power commander.
They aren't that expensive, will really pay to get one fitted, also easy enough to tweak if you decide to do more junk to it, eg, pod filters, wiseco 997cc big bore kit (part number: R997), skim the head, dial in cams, engine blue print
NO! NO! Bad filthy luka! must not mod fireblades...
p.s: what brand is that pipe? come on! tell me! DO IT!
oops, thats right, not a '92 fireblade :P sorry
part number: CK162 for the wiseco big bore kit, and it will be a 980cc not a 997cc..
Not that it needs it![]()
What sorta power commander is it? if its a pc3 you can download various maps for it off your pc, most of the maps arent bad from what ive heard.
Never let your enemy see your emotions, for it is the one weapon they will value most.
Running a power commander and exhaust without mapping it on a dyno seems like throwing power away to me. Not that I've done it but I will if I mod my CBR.
Sure dynos lie (for various reasons like tyre choice, air pressure/moisture, etc) when comparing bike to bike or dyno to dyno but there's no better tool to compare how your bike runs on different maps on the same dyno and same day.
Nice... congrets. So when can we do a CBR9xx cruise? so I can bring my 954 out for a group photo![]()
newbie since August 2004....
VTR250 (retired) / SV650S (Fw:Keystone19) / GSXR750(given up) / CB400(traded for 919) / CB900 Hornet / CBR954 (traded) / CBR1100XX (sold) / TuonoR (sold) / CB900 Hornet / NC700X / MTS1200 / XR250
I got a Power Commander II so it isn't fancy but it beats having nothing!
At the moment I am not so sure what I can do exactly with a PC II (if it's enough to knock out the flat spot and smooth things out a bit) as I haven't done fancy stuff like this before. Like the cover say '5 mins installation' and I am guessing it's plug and play right?
I visited their website and they have all this bunch of maps that I can download but I am not so sure if I can use it on the PC II and plus, I got a MIG exhaust (French Company that went outta business a few years ago, but I do believe retailers still sell their stuff) which unfortunately isn't listed.
So, a few q's, do I leave the PC on the bike?, What should I do in terms mapping and stuff?, Do I have to take it to a Dyno or what? (from what I heard having a PC III cuts out taking the bike to the Dyno, is that correct?
Yea, after Christmas aye? My mate also got 929, so that makes 3!![]()
Congrats on your new bike Mate - well done, and Take it easy!
"If you haven't grown up by the time you turn 50, you don't have to!"
congrats mate
Was doing a bit of research the other week trying to decide if a new can for the CBR was a happening idea.
From what I've read the maps you download for the PC III are enough to get you close but for best results you need to dyno your bike in your conditions.
E.g. a guy with a 929 in the rocky mountains with your model exhaust may come up with a great map for his bike the air there will be dry and thin. In the muggy (read wet) Auckland air at sea level (more o2 at sea level as the air is denser) your bike will need a different map for the same setup.
That said it'll be a shit load closer than the factory map would be with the after-market can.
Does that help? Not sure what the difference is with the PC II vs PC III though. Might be custom map only..?
PCII is an older version of PC,the main difference being that a PCIII plugs into your comp via USB port.
Is the exhaust a slipon or full system?If its a full sys then the HTEV exhaust valve has been removed,that will cause a real stumble down low in the revs.
If you put the PCII back on I'd reccomend taking it to GP Honda in tauranga,they have the dynojet dyno and are very good.You will have to block off your PAIR valve to get a dyno tune though,but they should know that(its an air bleed valve going to the airbox),it can be just clamped during dyno run too.
