Power Commander V

I installed a PC5 from VFJ years ago. The first ride out I got into water over the seats. Drowned the clutches but not the engine. Anyway my brand new PC5 was completely submerged for probably 30 seconds to a minute. I was having big issues for about a year after. The bike would run on one cylinder sometime and It would barely idle other times. I finally took off the PC5 and all related items to grease and clean it all. This helped a lot but not %100. So I repeated the process and left the PC5 in a bag of rice by the wood stove for a few weeks. While that was going on I put the bike back together and used it without the PC5. The bike worked flawlessly. Just had to deal with that pesky speed/rev limiter.
I gave the PC5 another try and this is the problem that will not go away whatever I do to it. If I decelerate slightly or try to hold the same speed/rpm the engine starts to lose power and bogs itself down. It's barely noticeable until you try and accelerate. To get it to snap out of it I simply back off the eccelerator slightly and the engines power comes back or I just keep pushing the accelerator down and finally the engine will come out of the bog but with a jolt because now I have the accelerator pressed down a lot more. I prefer the first method. I've gotten so accustomed to it that my wife doesn't even notice when it happens. Once in a while the PC5 doesn't act up but that's very rare. The only option left it to try and re-flash it.
I live in Ontario and I know there is a dealer in Ontario that will sell and program them. If I was state side I would go back to VFJ but If I can find someone local I will go that route. Does anyone know which dealer in Ontario will flash the PC5 or if it's easy enough to get a program and flash DIY I would try it.

I've been finding posts on here about others having the exact same issue with the PCV. Hopefully he has a fix.

VFJ has a fix. Something about the 02 sensor dummy plug throwing off the chip because of vibrations bellow 4000RPM. He has a tune that allows the factory sensor to be plugged back in to eliminate the problem. He's supposed to send me the program so I can do it myself.

There is no fix for a pcv...lol...they are junk.. you're lucky if one out of three performs like it's supposed to.. I put three different ones on the same bike many times new out of the box and all three results would be different with brand new controllers same mapping...do a reflash and be done with the bs

So rev limiter is an issue for you, but not running on one cylinder.

I'll try the new tune. It's free. If it doesn't work I might look into a reflash. I've heard a few horror stories with reflashes though so I'm considering leaving it stock. I don't understand why Kawasaki is the only manufacturer that limits there machines to 80. A freakin one cylinder Wolverine goes much faster then my twin 800. If Kawasaki doesn't wake up as soon as my oldest son starts driving his own machine I'll be looking at Defenders, Rangers, Pioneers and Wolverines.

I would rather a reflash. No more worrying about water or mud .

There's articles about Dynojet buying Dynatek years back. Might be like GM and Chev, same thing different badge.

Not sure what's going on with John. He told me last Thursday he'd send me an improved tune for the PCV but I haven't heard from him since.

I've never seen a post anyway that mentioned having an issue with a reflashed ECM. The only concern was speculation on how it could possibly affect warranty work as opposed to a tuner that could be removed.......again I say speculation as I've never heard anybody state they had warranty work denied. To be honest I would doubt a dealership would ever dive deep enough into the ECM to find out if it was reflashed, but it could happen.

JBS sells, or at least did sell, PCV/tuners setup to defeat the speed and rev limiter also. Don't want to get in a fight about who is better but had a riding buddy that bought a VFJ tuned one and the machine never did run completely right afterwards. When he bought his JBS clutch setup he also sent him the PCV to have JBS reflash it and it ran great for years and several thousand miles......same tuner, same machine, same person installing it.

Speed limiters in the 50 mph range are pretty common on anything but the pure sport machines. Not like the Teryx is the only one.

I don't know of any side by sides that are limited to 80 other than the old Rhino's (65km) and maybe the Vikings. The Rangers, RZR, Pioneers, Wolverines, Mavericks, Commanders, Defenders...None of these have speed limiters anywhere near as low as 80 if any. The Mule and Kubota are probably limited but they are more geared to industrial and farm use so I wouldn't say 50mph limiter is common at all.

I've seen reflash issues on Polaris bikes so that it why I am a little leery about it. At the time I liked the ideal of the chip because if anything goes wrong it's easy to remove and keep going. Knowing what I know now I would go he reflash route. Since I already have the PCV I'll try and get it straightened out.

Is JBS a forum member? I'd like to contact him about my PCV. I'm going out for a ride Saturday and I'd like to get my chip back on. It doesn't look like I'll get anything from VFJ anytime soon.

Doing a quick search on Polaris Ranger forums is stating that the top speed of even the XP1000 Rangers is 60 mph (96 km/h) on the 3 seater and only 50 mph (80 km/h) on the crews. Wolverine X2's, Vikings, etc... are all about the same

I'd be happy with 60. That's 16km/h faster than the Teryx. When my chip is off and my father in law sails past me in his Wolverine that hurts the ego a little. Ho loves it though!!!

I hit a mudhole today. Locked in 4 wheel diff, 28" mudlights. Full throttle, speed, mud and done. Without the help it would have been tough. My daughter says Dad I have Mudpox!!!!!

I jus got the new tune from VFJ. He says to load it and then hook everything back up without the dummy plug and leave the o2 plugged like factory. I'm hoping to try it out this weekend but I'm still waiting on a stator that was supposed to be in Wednesday.

Got my bike back together after some extensive maintenance. I went for a quick ride last night with the new file installed on the PCV that excludes the use of the dummy O2 plug and the bog is gone.

I was skeptical at first after hearing from some that the PCVs simply don't work but looks like the one I have works like it's supposed to. Mint!!

Thanks for fixing me up VFJ

Just put a PCV in a stock 2018 Teryx 2 with VFJ's mapping. No O2 dummy plug/bypass for mine either.

They let us run road in some places, and I was creating traffic chaos with the 50mph limit (folks blowing past in perhaps not the best of passing places), Plus, then I was trying to hold 49mph to keep the engine from cutting out constantly and it was pretty annoying.

John hooked me up too and it's wonderful. Cranked up to 61-62 easy enough. I didn't leave the pedal mashed on that road, but it might do a bit more, and probably faster without the full windshield for sure. That's all I was looking for anyway and it's a way more better machine now. Probably want something other than a crappy 4 ply tire anyway if that's going to be a regular thing too.

Back by the rear tire drivers side under the box, there's a big wing nut on the parking brake cable. Loosen that up and it's a hell of a lot easier to get the center console out if anyone is interested. The big gray plugs go inline on the stock wire harness on the passenger side, about mid way on the air box if you're searching for that too.

Thanks VFJ!!
