Power Commander or not?
Is it ok to run yoshimura trc full exhaust on 09 zx14 with only a k&n filter and no power commander? Will it run the same as the jardine rt 5 slip ons? Or is a pc absolutely needed with a full yosh system?

Similar discussion here, might want to reach out to someone running your pipe & get feedback before & after

Personally why bother with a full system & not get a good map. Then get block offs and I forget if your year is a good one to pull the flies on, but the search tool is your best friend.

The norm is if you change one, no PC is needed. Change both and you do. It will go too lean. As lean as todays engines run, I'd put one on it even if I only changed the pipe.

Power commander is cheap compared to rebuilding a motor. If your going to buy
a full exhaust why not maximize it? Just my 2 cents.

Everybody is talking about lean conditions. Aren't all year zx14's stock maps rich as hell? My 06 only has 2% fuel added in the top of the rev range with a 40 shot of spray. And I still think its rich if the weather is not right.
I remember Brock complaining about this in his diaries as well.
But, either way, rich or lean, to maximize your gains you need a PC.....

Consider it cheap insurance along with a good tune. As the previous posts point out, the stock mapping is a compromise. Kawasaki knows most owners will fit a pipe so the WOT mapping is a bit rich in OEM tune for that reason, particularly the 08' and newer gen 1 bikes.
I had an '07 prior to my '12 and the PC3 and custom mapping made a noticeable difference both up top @ WOT and more importantly, with mid-range throttle response. The bike also ran significantly..cooler after being tuned despite me being in Florida temps year round. Leaner tunes run hotter (good for emissions/cats which is why the factory does it)
Likely without it (a PC & tune) you could experience...both conditions, a bit rich at WOT and lean at light and medium % throttle (everyday...normal riding) where the OEM tune is done more for emissions (leaner) than max performance.
Lastly, for the record, my '12 is getting PC V and a custom tune in a couple weeks when my exhaust goes on because without that PC and tune..it would not be optimized for all the preceding reasons.
Good luck,

Thanks, I was told by jeffo to take flies out which i did yesterday, I was sent the wrong power commander 5 model 17-009 for the er6n I need the 17-012 for the zx14. Once I get the right power commander, I'll put on my full yosh trc. I thought about using the map on a flashed ecu, leovince what made u choose the PC over flashed ecu?

Good question, actually I am doing...both on my '12. Re-flashing the ecu 1st, then installing exhaust, PC and having it custom tuned. With the fly's out you would definitely want it tuned for your local conditions as it would for sure be lean at low and moderate rpm's with the pipe installed. That said, Yoshimura is a good quality pipe so I expect you will be happy once you get the correct PC and have yours tuned for how you use your 14.
Good luck with it,

The value of a PC5 is not just added power, its added information. Every bike arrives slightly different (every 14 and every 12 etc.) as such, every set-up is in turn a different tune. The thing I enjoy the most about the PC5 (and all the add ons) is the learning experience it provides. As simple as 'on the stand' garage idle set-up, with your laptop connected and the PC5 reading out the real-time changes you can make, thru to full PC5 Auto Tune with a wideband screen on the fly, to map switching on juice, is really amazing and fascinating to the die-hard motor-head, of which I'm one.....The process gives you a better understanding of the 'art of motorcycle tuning' and takes away the "I wonder if I did this".......Once you understand the F/A cause and effect, it makes you stronger.
