2016 SPortsman 450 ECU tuning release

Ok guys and gals, here it is!! Tuning for the 450 is ready. HUGE gains on this little machine! Check it out and let me know if you have any questions other than when is the 570, 850, and 1000 tuning going to be ready. :biglaugh:

570 we had to make a few changes to as the tuning is much different with out being fly by wire. Should have it very soon!!

Here’s the details and a pic of the stage 1 final dyno run. Thanks for being patient with us!! It takes a lot of time to do some of these tunes and reliability and safety are our number 1 concern. Pricing starts at $449 and goes up per stage.

Speed Limiter Removed
•Rev Limiters raised
•100% Throttle opening vs. factory 30% limitation
•Improved throttle response in all modes
•Improved ignition timing advance optimized for 91 Octane for maximum power on stages 2-5
•Fueling adjusted for aftermarket components (intakes, exhausts) for optimal Air/Fuel Ratios
•No need to run a "piggyback" fuel controller with our reflash for most bolt on mods (You are responsible to make sure your mods are compatible with our programming – Most aftermarket companies’ exhausts and intakes are compatible with our programming)
•Torque Limiters removed for a much more responsive and fun vehicle
•Cooling fan on temperature is lowered by 20 Deg F, but can be set to whatever temperature the customer wants

•Stage 1 is 11 WHP (50% HP increase over stock!! Factory intake and exhaust, 87 octane)
•Stage 2 is 16 WHP (Factory intake and exhaust, 91 octane)
•Stage 3 is 17 WHP (aftermarket intake, factory exhaust, 91 octane)

Rancher 400at locker options

I been looking for a Detroit gearless locker and can’t find one for this four wheeler. Detroit said they quit making them. Don’t want a spool. Has anyone put something from another 4 wheeler in this one? Or tried the washer thing and it work?
I have a spare parts 01 rubicon but I thinks it’s a spool in the front.

Would love to put a selectable locker in it out of something else. I think Foreman has them in some the way I understand.

Snow blower brush mower etc………

Hi guys!!

I’m not sure if this belongs here but here goes!
I’ve been told the snow blower that hooks up to your quad in order to be pushed, are hard on belts and the machine.(I’ll be running tracks in winter) Any truth to this? I’ve been researching some of these blowers …………Man! THEY ARE EXPENSIVE !!!! You can buy a lot of bling for your ride for their prices!

I also am looking at getting a rough cut tow behind mower. They too are not cheap!! I wanna "hog" my hunting spot near apple trees , and hire myself out to do other hunting spots lawns etc. anything really to help offset the cost of it and maybe a blower. Any ideas? I need a pretty heavy duty mower capable of taking care of 1.5-2 inch diameter bushes ………..Brands too would be appreciated!!………Just remember I’m in snowy ole Quebec Canada! I have been looking at "Berco" and "Kunz"

I finally found the answer to the gear indicator problem

After searching and searching for the resistor pack for these newer Sportsmans because it’s an obsolete part number because it’s a sealed unit and in order to replace it you have purchase the entire harness, I finally found a resistor pack harness kit. I ran diag on the speedo display and my "low" position was out of spec. I replaced my gear position sensor last year, and it fixed only half of the problem. Anyway, here is the ebay item, Electrical Resistor Module Harness Kit 2014 Polaris Sportsman 400 2204890 | eBay

If any of you are having the same problem as me, then I recommend running gear circuit diag and shifting through the gears to make sure your resistor pack is working correctly and keeping the ohms within spec. You’ll need your service manual in order to get the correct ohm specs.

Maybe I’ve been living under a rock but it took me forever to hunt this part down. RZR’s and other various models had a connector style resistor pack that was replaceable but not mine.

Rear Diff Issue. Any Ideas!?

I noticed my Grizzly 450 was leaking oil. Upon further inspection, I found the nut and washer holding the driveshaft in place had come off. Luckily I found the washer and have replaced the nut, but cannot do the nut up with any spanners or sockets as none will fit in such a small space! How on earth can I tighten this up!? Is there a special tool or technique!?!? Please help! Pics attached…

2012 sportsman 800 EFI

2012 sportsman EFI

ATV will start but acts like it has a misfire, loads up and smells rich of fuel.
if your genital you can clear it out and it will run good except it seems load on the top end like valve chatter.

I replaced plugs. found wear into the copper on the mass air sensor wires. repaired wires. cleaned and then replaced mass air sensor. checked valves but looks like they are not adjustable with hydraulic lifters.

pulled fuel tank and cleaned. inspected fuel pump and cleaned screen. looks like good fuel flow from injector line. put ATV back together. starts but misfires in reverse now.

lost on where to look next.

Thanks Marcus.

Moving from Outlander XMR 800 to a Renegade 570 XXC…. thoughts please?

Hi guys,

I’ve posted this thread on the Renegade section, but thought it would be useful to get an opinion from Outlander riders (plus there are more people currently viewing!).

To cut a long story short, I’m a current 2012 Outlander XMR 800 owner from the UK (Surrey), and could really do with some advice regarding my next purchase! Having competed in Croatia Trophy this year my bike is pretty battered and has been unreliable, and I’m tempted with a good deal I’m being offered on a 2016 Renegade 570 X XC – I’m drawn to the reliability of the G2 over the G1 as well as the 3 year warranty as I have limited time (and expertise) to do a great deal of mechanical stuff myself so this is a pretty big factor for me.

I have a slight concern though – a couple of people have mentioned that the SWB of the Renegade will make the steep ascents / descents and off camber stuff more tricky / less stable – I’ve only ever experienced the LWB XMR Outlander so I’d be really interested on rider experiences of this before I push the button on the purchase. My riding terrain when we compete is pretty extreme so don’t want to make life more difficult or dangerous!! My riding partner uses a LWB Outlander so I need to make sure that he doesn’t end up with an advantage over me or I’ll end up slowing him down in a competitive event.

I do like the idea of something more agile and lighter, and I think I’m less concerned about the power as I tend not to use it on the road or for fast xc, it’s more around the ability on the technical stuff. However I would also be interested in opinions on this.
