Hi guys I need some advise or replacing my stock exhaust on 2010 Honda Fireblade , which exhaust should I use I'm gonna keep stock headers and just wanna louder system as the standard is so quiet lol ... I need to know about the O2 sensor is there a slip on that will fit the original O2 sensor back in after removal from ltd system I don't really want to fit PC to machine let me know best route guys if I do need a PC then that will have to be done thanks in. Advance guys
Im the same as you stuzza 11 i have a 59 plate blade scorpion have the boss for 02 sensors and i phoned a honda dealer and they said all aftermarket exhausts bought in uk for uk bikes should have the boss to fit the o2 sensor....but in the same breath i know nowt about anything to do with these sensors
Have you tried the flapper mod for now? Its all I am doing on mine and it just makes it sound a lot throatier, I know, its still quiet compared to some, but your not likely to get nicked with it either
Most will have the boss to screw in the O2 sensor ... if not then disable it and use an O2 blanking plug. The bike only uses closed loop anyway for emissions so no big deal... However, any exhaust change requires fuel mapping to get the most from it.
Hi Ya Gordy I have done some reasearch of late on the whole exhaust thing.. as I was exhausted of reading tons of articles on how nyou have to remap etc etc. Now then now then lol are we sitting comfortably ?? there are some mixed opinions on this subject. Two different types of rider 1. Racer 2. road user. I have just purchased a black edition exhaust from Racefit. I purchased the titanium with the baffles for M.O.T these are optional if so wish to use them . The pipe will come with the stock o2 sensor pocket fitted. (John at racefit is superb and very helpfull) well worth a telephone call matey ... I spoke at length with John at he has given me lots of advise, he has also been into bikes since the age of 6, e is now 52 something. I was told by John that changing the end can will have little to no difference to the day to day running of the macine, the standard o2 sensor is in place and regulates as its supposed to do, John also said "lets have it right" the main of us like to take our bikes out for a quick blast on roads and look and sound good unless we are racers of course, in general we are not looing at huge BHP gains but yet a rich tone to the exhaust etc etc ... So with that in mind do we need a PC5(power comander 5) well John also stipulated that this would not be required also he said that there are two types of people. One of which will listen to all the sales man trying to sell the PC5 and custom mapping and think yes i must have it, and the other who thinks lets bolt the exhaust on and off we go .... but really can any of the road users say they need that extra power they use that extra potiencial or can they actually ride that bike to uts potiencial i very much doubt it. so in my opinion it would be entirely upto personal preference . My exhaust comes this week after I have fitted i will post vids and pics etc see what you think. I will be running standard headers, stock O2 sensor and no custom mapping as yet the bike has plenty of power as stock for the road and that is my main domain road use untill i become rossy or marquez i wont be bothering but once again matey its up to you ... let me know what you decde and how you get on someone is selling a noice exaisut on the forum at the min a yoshi i think mint looks and sound lovely they do...
Agree with Stuzza11's comments............ However MR OCD explained it more accurately. I've just had my 2015 blade mapped after I fitted a RaceFit Black Edition exhaust. Once on the dyno, it was found to be running lean on the stock map in the 2k to 8k rpm range, not dangerously, but lean. This is due to the Honda Map being required to meet various emissions standards in Europe. Even more stringent standards on bikes destined for the USA market.
Exhaust Manufacturers : They'll say you don't need a PCV or a Remap, as they don't want you to think you need to spend another £400 on top of the price of the exhaust. Tuners : They'll say you do need a PCV and a mapping session, because that's their business. You : Do you want to spend £12k on a bike and risk it running lean and damaging the engine for the price of a PCV and a mapping session. The choice is yours.
Hi all sorry for jumping in on this but I also could do with advice been looking for a can on my rr 6 if I went and and put 1 on do I just disconnect the power command or do all after market cans have a power command fitment I might be asking the bloody obvious but please accept my apologies now as I'm as much use as tits on fish with spanners and mechanical stuff
A power commander is just a black box which takes ECU signals and interrupts them and puts in an offset fuelling value according to the calculated air fuel ratio required. Usually found under the seat when fitted. They are an aftermarket device fitted to fine tune the running of a motorcycle following the removal of the standard exhaust which due to the loss of back pressure (and cat in some circumstances) can cause the lean running of the fuel mixture which CAN have negative effects. All a PC does it to remap the fuel tables to add or remove fuel for a given throttle opening calculated by the air/fuel ratio decided by the unit. Most aftermarket and standard exhausts will have an O2 sensor fitted so that the ECU can set the air /fuel ratio to give a lean figure for noise and emission regulations. The sensor can be removed from the standard bike and refitted in the new exhaust to allow the same results. Running a PC or a Bazzaz (essentially the same thing) it would be unplugged to allow the PC to do the AFR, not the ECU.
If removing the standard exhaust, you will probably find a servo valve with cables going to it which open and close a flap in the exhaust, this isn't needed and really only comes in to play in the low rev ranges to quieten down the exhaust and some say the bike may be smoother because of it. Just do a search on here to find out how to remove them and there may also be the O2 sensor fitted. Just unscrew and refit it into the next exhaust. Not up on the RR6 but I'm sure you'll find the advice you need on here. Just post the question and start your own thread.
You forgot to add Insurance Company : Don't usually charge much(if at all)for a slip on exhaust,so would prefer you to fit PC as they can then hike your policy up for the privilege of having a better running bike with no discernible power increase
Silly question but if your unplugging the lambda sensor and putting the blank in then how does the pc5 or ecu know what air fuel ratio to add?
In short it doesn't. The PC5 is open loop and does not self correct so there is no need for for a sensor. In fact you need to disconnect the lamba otherwise it will 'fight' with the PC5 commands to the injectors For a given RPM and TPS( you can add other variables such as temp/gear etc) PC5 will provide a set fuelling, - this set fuelling was determined on a dyno for best hp/torque response, so essentially it was optimum just for those conditions. So as soon as you leave the dyno and conditions change you may not be running optimally. - but in reality unless you dynoed on a mountain and rode at sea level you would not notice. The stock lamba is only narrowband, its main purpose is to lean out the AFR in certain condition like constant throttle etc. You can upgrade to a wideband but thats a whole other story
