Do i need power commander?

[boom123]

I am sweet looking the 2 Bros!
If I end up buying them with a K&N filter do i need to get myself
a power commander also? I mean is it really necessary because I'll get wayyy out of budget then....

No need to get PCIII after pipes and K&N. The only benefit of PCIII is smoother throttle response and maybe one or two horses. Also PCIII without custom map is useless. The total PCIII+ MAPPING IS ~$500 i believe.

i bought the 2 bro's and K&N last week, I went ahead and ordered the PC since i plan on gutting on the intake box for more airflow. If i knew 100% it wouldn't hurt going w/out the PC I wouldn't of bought it, but too late

Are you 100% sure about this? I know that you can get a map from PC site according to the exhaust you have for free....

I think he meant 300 for the Power Commander and 200 for dyno time for a custom tune

Those maps are crap. Every bike even if its made same week will have something little different than the other. Please tell me since when DO IT ALL STUFF is good doing everything? its average or less on everything at the most. Custom maps are made accordingly to the location/condition of the bike. For example. My bike never sees anything worse than 95-98 Octane pure gas (no ethanol) and i live in Tazmania. U wanna tell me that it will be same map for you guys in Florida and in Idaho and you run what? 89(10% ethanol) if i remember right. 92 at the most. So if you get PCIII only custom tune will do. That the reason for it in first place.

As for Pipes +K&N making bike run lean - bullshit. Its FI, not carburated, so it will adjust to some degree (pipes, K&N, air box mod) The manufacturer made it this way so you don't seize your fuckin engine only by putting different brand of filter on and a set of pipes

Are you riding your bike to it's fullest now?

If so the a power commander will be a good idea and you will only get the most out of it with a full exhaust system and upgraded air filter system.

pre '06 FZ6's don't have an O2 sensor to read if the engine is running rich or lean. Outside of intake air temperature and maf sensor, I don't think the pre '06 FZ has any sensors that the ecu can read to adjust the air fuel mixture

No I'm not! that's why I am asking if it's really necessary for now...maybe in the future I'll get one....

My FZ6 it's a 2006 model...I didn't quite understand...can it adjust or not?

My general question is that if there's any chance for the bike to malfunction with the absence of a PC....

Please don't post octane ratings, your going to make this thread go wayy off topic for you blatant disregard for the owners manual, haha.

But honestly for the $225 that the PCIII costs plus the downloaded map from the site, it makes your bike way nicer. How much power does the exhaust net? 3 hp? WOW that's the same as a PC and no one gets mad at people for spending $500+ on exhaust.

You don't need it... but you are really going to want it. I did two bros + k&n on mine, and the FI just was not up to snuff to satisfy me. Jerky at low speeds, popping on decel, sluggish at low rpms... you'd never regret spending the extra $200.

If you change your exhaust you will want a fuel controller. The bike will run lean and you can risk burning up your head over time.

The FZ is fat from the factory as others have stated. Yamaha builds this into the stock fuel in anticipation of people adding an exhaust and other tweeks. Me thinks your motor will be fine.

The beauty of the PC3 is a tuner can totally dial your specific set up in.

Simply not true....at the least, its VERY misleading how it was said above.

A reduction in backpressure will lean out the engine a LITTLE...but its a MUCH bigger issue on Vtwins (that NEED more backpressure) than I4s.

The FZ6 exhaust is about 5 feet of tubing, containing multiple bends and TWO catalytic converters (on the 07+ models anyway).

Changing out the muffler, hell....REMOVING the muffler is NOT going to cause the engine to lean out to any measurable degree on this bike.

I'm just curious as other people have stated it. But is this fact that Yamaha does indeed program the bike on the rich side so people can modify the bike? Or is this just internet legend passed on from thread to thread. I'd like to see the actual Yamaha documents saying "We purposely made the FZ6 run rich for all you tuners."

I just went and read the warranty info on the bikes, even if these internet claims that Yamaha has built into the feuling the ability to compensate for aftermarket exhaust. If your bike breaks because of it don't go crying to Yamaha.

directly from the Yamaha warranty pdf.

3. This warranty does not extend to:
a) MOTORCYCLES which have been modified
in any way from the standard specifications
as shown in the Owner's Manual, including
any MOTORCYCLE whose odometer has
been altered;


b) Use of lubricants, oils and fuel/oil mixtures
other than those recommended in the
Owner's Manual, improperly installed
accessories and use of parts or accessories
that are not equivalent in design and quality
to genuine Yamaha parts;


This is strictly from a Warranty stand point. I'd still like to see some Official Yamaha words that the stock fuel is set up for aftermarket parts.
