power comander

[davey boy]

Hi just joined got a 2007 fz1 done a few mods mostly cosmetic but have put on a scorpian slipon can, bmc airfilter and the fce chickened out of cutting the airbox
Do i need a power comander or will the engine run ok and if i do get one is there a map to suit my bike set up or will i have to get it on a dyno
Ps any rideouts up north i live on the west coast of cumbria
Thanks in advance Dave

Hi Dave, and welcome to the foc-ers!

You should be ok with a can/filter, the bike 'should' be able to deal with the increased airflow. I ran mine this way for a few weeks with no problems. I then got a tb juicebox, and started experimenting!

Exhaust can fine airbox and kn only when you have power commander as bike will run lean

[slimwilly]

Used  Power commander 3s are in demand as the hot rod boys get the handed down FZ1s s, first time owners probably love the bikes as they are,lots for sale still with the Dyson can still on,lol


Get fettling and saving,not easy with a toy in the shed like that,but it's an interest innit ? :lol

Ive got a hacked airbox and cat-gut (+air injection thrown away) and run a PC5 (I got cheap on fleablag).  I download someone elses map (a pack of them) from one of the american forums and the mid-range is waaaay stronger and smoother.  I could dyno it, but there are enough tried and tested maps (that mainly bypass the 5000rpm emissions homologation nonsense) to give the bike a proper litre-bike midrange and not an EU-strangled middle.

I'd go for a PC3 or PCV, heck mine is probably worth just as much as when I bought it or more - if you don't want it just bung it back on the 'bay.

[davey boy]

Thanks for the replies think I am going to go for a PCV if I can get one at a reasonable price do I need an oxygen sensor or anything else with it

I just got a brand new PC5 for 227quid via a French bike shop on ebay, much cheaper than usual due to the good exchange rate to the poor euro........they are usually about £300.


Ive been watching ebay for a while now and the PC3, second hand are going for circa £160-£170 there really is the demand for them at the momen....i think it's a bit steep, i was willing to pay £150 tops, ideally £130 but hey ho that wasnt to be.


I've heard of folk getting rid of an o2 sensor but not exactly sure where it is, i presumed that it would be within the exhaust and mine is most likely gone since i have an afermarket can but maybe someone can shed some light on the matter as to where this sensor actually is?


The airbix mod is well worth doing just for the induction noise  8) , [size=78%] unless you use a tank bag which spoils the noise a bit.[/size]


Pilingas........any chance of pm or emailing me a map for the pc5 that you feel is a good starting point.....pretty please?

[slimwilly]

You will find the o2 censor on the side of the exaust under neath,just uplug it,thats what we have done,,i hope the pc5 fits the bike

[pilninggas]

I'm running an o2 eliminator that just provides a constant 0-1v square wave.  If the ECU goes closed loop, it just tells it that the bike is running stoich (even though it might be a touch rich with a custom map).  I guess these bikes only do closed loop in quite a small area of the fuelling map anyway, at very small loads/throttle openings (3000-7000rpms, with less than 20% throttle?), everything else (1000-3000 and 7000+revs or greater than 25% throttle) will be open loop to have anything like useable driveablility and emissions.

[davey boy]

I have ordered a pcv that comes with a o2 sensor eliminator just wondering where does it plug in and do you have to remove it to upload new maps

[slappy]

They come with full instructions and are very easy to fit with the multiplugs attached. To download new maps just connect to your laptop with the cable provided, no need to remove from the bike.
I don't have a pc5 but I have a Juicebox Pro and they fit exactly the same, it took me less than an hour to fit it, the only thing that took any time was identifying the O2 connection and fitting the 02 eliminator,getting the 02 multiplug apart was a pain as it was an extremely tight fit.

[davey boy]

Yeah just looked on YouTube looks pretty simple might do the air box while I have the tank up

Installed the power commander v today can anyone suggest a map
I am running a scorpion slip on  a bmc air filter and a fce
I am going to get it dynoed when I can afford it
I found the thread with different maps for the pc3 anyone know what the different stages of mods are

I just used the map in the pack closest to my own spec - maybe called duken's smoothed map or something. There are loads of maps for end cans and air filters, just don't use the junk maps on the dynojet website.

[davey boy]

Sorted thanks , now to get it mot'd and see how it runs

[davey boy]

I have downloaded the map pack from the other forum and the only map for a pcv stage 1 mods was the wissleblast smooth or something so i used that but i find it a bit dull just realy liniar and maybe less power anyone have any other sites with maps i can try before i go to the expence of getting it dynoed

[devilsyam]

Davey do the airbox mod flies and decat or your wasting your money at the dyno

[slappy]

I think you mean the whitlebeast smoothed map
Lots of people run it but when i tried it  i found it gave me hot starting problems, don' t know why.
The only thing to do is just try different maps until you find one that suits you, everybodies taste and riding style differs.
The only place that seems to have different maps is the american FZ1OA site.
I have a little route I use to do tests on that is about 22  miles so I could do back to back tests on easily, its a bit easier with a juice box as you can have up to 10 maps loaded and just switch from one to the other with a little screwdriver.
The one I have found best for me so far is a pc3 map which is for an Akrapovic can, fce and  02 eliminator, even though  I have a Beowulf can fitted.

[stevierst]

As the last couple of posts have mentioned, you really need to do the secondary flies, airbox mod, and an air filter before attempting the remaps.

I did all my mods pretty much all at once, fitted my juicebox, and started playing.

The difference was incredible! Yes it was was linear power, but it was a Hell of a lot more than standard. As a sports bike it was great when modded!
