Hello and sorry my bad english, i live in Finland

I just bought new polaris 570 eps tractor model and top speed is limited to 40kmh. I dont know is it same there in states. Its 2015 model so its with electric throttle and nobody in finland dont know how to remove that limiterr even importer of polaris. Its bit too slow that 40kmh in forest or snow.
Here is only three 570 2015 model registered in finland so thatelectric throttle and limiter is new for everyone.

So does anybody of you know how to remove that electric limiter?

 

[cariboo]

maybe they have different keys like the ranger but i am not sure

 

[RVS Performance]

Has low and high gear?

 

[Joon4Z]

No it not a key. And its same speed with high and low gear..

 

[golf12]

First off welcome!.. That's very strange.. Just to understand.. You're saying that the machine will not go faster than 40 kilometers per hour in any gear?..

 

[Joon4Z]

Yeah thanks.. its 40 kilometers per hour with L and H gear..
I think its only in finland this f***ing speed limiter..:damnit:

 

[Maximus510]

You say Tractor model...do you mean it has tracks instead of tires? Can you post pictures of the unit?

 

[RVS Performance]

Does it misfire or anything at that speed? What rpm is it reading at top speed? If there is a limiter programmed into it, you should be able to program it with a US program instead. Might have to send it over here to have it done though.

something has got to be horribly wrong.. Take it back to your dealer and ask some questions.. Are the brakes locked up or something?.. Speed governors are not a new concept but 40km's p/hour is absolutely useless.. Being a Fin, you should be able to relate to this.. Finnish NHL players Olli Jokinen (Nashville Predators) and Mikko Koivu (Minnesota Wild) skate about 40km's p/hr top speed.. That's really fast on skates but there's no way your machine is set up to only go that fast.. I saw an episode of dirttrax television a while ago where they went riding in Finland.. They were going full out (very fast) and there was certainly no mention of speed governors.. Is that related to using the machine on public roads or something?.. What good is a trail or utility machine that only goes 40kms per hour?.. If that's true your government is even more screwy than we have over here in north America.. ha!

This one?

They glued a piece of plastic in the accelerator, just screw up the top part of the box that's above the throttle and you can just pull it out.

Or at least that's how it works on the 2014 model, am not 100% sure if it's the same on the 2015

40 Km/hr

What is your Revolutions Per Minute (RPM) when running at full throttle?

 

[Joon4Z]

Okey, so now the importer of polaris says that i need to cut one wire begind the speedometer. I have ten wires there but now i dont know which wire i need to cut. i put two link to my pictures and if somebody of you can take two pictures from your speedometer so i can compare those pictures and cut right wire. you can send pictures to my email [email protected]. thaks!

[DarthBadger]

I would assume it would say which ones do what in the service manual.

 

[Joon4Z]

where i can get that service manual? is it free somewhere?

 

[DarthBadger]

I got the manual when I bought the ATV, don't know if you can get it online. Maybe ask your local Polaris dealer?

 

[Joon4Z]

i found this text.. is it that electric speedlimiter? so now somebody can say how i can remove that limiter? :rotflmao:

Speed Control
The speed control system utilizes the ECU, Speed
Sensor, Solenoid Valve, and engine vacuum from the
throttle body to operate. The ECU powers the system
through the ECU/IGN/FUEL Relay. When the speed
sensor signal rises over 40 Kph (25 Mph), the ECU
triggers the solenoid valve to open, allowing atmospheric
pressure on top of the air control body diaphragm which
limits the amount of air entering the engine. Once the
vehicle speed drops below 37-40 Kph (23-25 Mph), the
solenoid valve is closed by the ECU and the operation
repeats. Should the vehicle speed reach 67 Kph (42
Mph), the ‘check engine’ light will illuminate on the LCD
gauge to indicate there is a problem with the system.

why is it limited?

Cause it sounds like the ECU is going to scream at you that your engine is messed up if you exceed the 42 mph. If it's the tracked model I posted before the limit is because of the amount of wear and tear pushing those tracks at those speeds can do. it's a preventative measure to help keep your machine lasting longer. That being said, 23-25 mph on tracks in snow isn't slouching. How much faster are you wanting to go? 30? 35? 40? in reality, those speeds really should be left to the snow machines that are designed from the get go to run tracks and to move things that quickly. The tracks on the 570 are essentially an add on. as the machine was designed to run on tires. So adding the tracks increases the weight, the force required to turn them, the wear and tear on the suspension as it now has to move more weight which has more force when it's moving. Etc. Etc. Etc. all the way back to the engine. Because of the gear reduction in the tracks the engine has to rev up that much faster to get the same speeds. so limiting the revs just prevents you from blowing up your motor. I know we all want the most out of our machines but some times there are limits put on things for a reason. Just be aware that if you cut that wire I'm sure you're voiding all warrantees that might be on that machine.

 

[Joon4Z]

My atv is with tires no with tracks.. so that 40kmh (25mph) is bit too slow..

 

[ThorsHammer]

is it geared differently than? what does tractor version mean over there?

With a top speed of near 65 mph why is your machine going to freak out when it reaches 42 mph?

I'd find out why it's limited before I went cutting wires. Just my $0.02
