You have a pink wire you must connect to a black/blue wire. its under the plastic by the belt guard, or your snowemobile will be set for ethanol. one sled went up 20 km/h just by doing that

This seems a bit weird

The 09's are supposed to have a switch for that under the hood, Ethanol "on/of".

How and where did you get this info?SOUNDS A LITTLE SKETCHY!Please explain?

i work in a polaris shop here in sweden,and we have had huge problem both with mpg and the performance,but this week we got a rapport about these wires.i dont know if its just the european sleds that is set in the etanol mode, but just to put these two wires together made it a whole new sled.so check it out. pink and black/blue under the plasic cover over the beltguard

Ok your a little far away 'will check with dealer if this applies to North American sleds.

Thanks for the info could be helpful

Aren't those the two wires that initiate the self-destruct sequence?

Kidding.

I'd love to play with something like this. Word from Polaris (as I underand it) is that our sleds are all tuned to run on 10% Ethanol blends. This is all fine and dandy info to have, except for the fact that I ran almost the entire year on 10% Ethanol blends and I STILL got crappy fuel mileage.

If it's just a matter of putting 2 wires together, then I see no reason a simple "ethanol on/off" switch couldn't be easily installed on ANY of these sleds with a $1 hardware store switch (as is referenced in the earlier rumor/fact? written above by Chumslick.) Then we could experiment a bit and see which setting makes it run better on whichever fuel we happen to have on a given day.

Magic, is there any chance you could get your hand on this bulletin (or "rapport" as maybe you folks in Sweden call it) and share a copy? Or just get us a Polaris bulletin number or something like that, so someone here in the states could research and get a copy of it so we can see what it actually says?

Not that I doubt your word, but I'd prefer to have a little independent confirmation before I start randomly crossing wires on my machine. Our sleds here might have a totally different setup and fuel map from those shipped to the other side of the pond...we have no way of knowing right now. My machine is in the shop for the next few weeks getting some warranty work, so I can't even look for the existence of these wires at the moment. Maybe someone else here can.

Regardless of whatever other info you can get us, thanks for the tip!

Hi Magic 23 How's winter in Sweden? are you still running?

We still have a least 2 weeks running in Quebec Canada maybe more further north.

Same as craze1cars my sled is in for warranty work,getting a new motor.I can't check these wires' maybe Chumslick can, and get bactk to us.

Thanks

i asked my dealer about it yesterday, and he hadn't heard or seen anything like this.

There is a black/blue wire and a pink wire on my 08 700 Switchback. It is near the clutch side cowling plastic at the top near the tab that attaches the side pannel. These two wires will plug together as male and female connectors are attached to them. I am riding in Northern Vermont today and tomorrow. I currently have 2000 miles on my sled. My mpg has varied from 12 to 15 depending on conditions. I will report on what effect plugging the two wires together have on this trip.

yes,thats the right cables,

If someone would PM me their VIN number, I can check any bulletins for that sled.


Don

Just checked my 08 Dragon RMK155 and it has these same wires with male and female termination. Now comes that moment of truth. Do I dare connect them and possibly initiate the self destruct sequence?

Interesting...

Come ON somebody under warranty plug those suckers in and let er rip. Then tell if it survives.

This is completely false. The wires do no such thing.

Does someone have a wiring diagram to see where these wires go to?

Black/blue is the ground for the sensors. The pink is labeled "data logger" and runs directly to the ECU connector A. There is another white/brown wire in the group labeled "mode change #1" that also runs to the ECU. Perhaps this mode change wire has something to do with it?? I dunno but without more info I wouldn't be plugging in random wires to see what happens.

Sounds like a recipe for disaster ,if black /blue wire is ground never a good idea to hook up any other wires to a ground circuit.Things could get smokey!

Leave it alone.

Agree with Compfusion

a guy at work had a zr900 and he piped it. In the directions there were two wires he had to hook up like he was running ethanol. this was to RICHEN the sled not lean it out. sounds like about the same idea.

I´m also a Swede and I got this done on my Dragon SB 700 this past friday and it became a new sled, feels like someone poured a bag of horsepower under my hood, guessing 15-20 horse increase, will definitely need to redo my clutching again..

In addition to the "wire connecting" My dealer did plug some new software into my sled, what it was and what thing that did the biggest difference I don´t know.

We had quite bad weather this weekend so I just got about 100km on saturday, but it seems that the fuel consumption has gone down radically. After that 100km my fuel gauge reads 2 or 3 dots above 1/2 tank, (I have never checked how precise the gauge is but it should have been lower if I compare to earlier this winter). Another sled altered by my dealer was as low as 21 litres/100km meassured more exact, (whats that? about 11,3mpg or so??), and for our riding that is OK I think as the 600SDI:s I know of are about 13-15mpg.

Wouldn't this be the same on 07's as well? Sounds like someone got a reflash (which improved mileage) and is claiming it is the wires?
I have a schematic for an 07-08's which should be the same as the 08's. Somebody figure this out right away.

we got a reflash here in sweden called cfi 700 international. but the biggest diffrence is the wires,the new reflash ,we got just makes go a little cleaner, but the increased power is from connecting the wires

This is very interesting. The dark blue/black wire is directly connected to the ground of the egt sensor as well.

So this pink wire must be a parrallel resistance to lessen the total load in ohms and give the engine a signal that may improve gase mileage. I am going to look at my buddies cfi that fricken rips. It would be very interesting if for some strange reason his pink, and darkblue wire are conencted.

Canada dragon guys who's sleds rip, you guys need to check for this as well. It is at least worth a look. should only take 3 mins to verify.

is this only for the 700's, or maybe the 600's too?

I checked my 07 Dragon and I could not find these wires anywheres accessible. My 08 Dragon RMK 155 has them just as noted. Too bad POO wouldn't save us from ourselves and confirm their purpose. The ol finger is hovering right above the self destruct button.

These are the same schematics as in my 07 Tech Manual. The 08 are indeed different (if they represent what's in the sled).

I rode in temperatures ranging from 0F to 35F with these wires connected. There is definitly more power available. I did not see any increase in gas mileage ( 12.6 ) as I was having so much fun with the cleaner running engine that I held it open longer and used a lot of brake to slow down and repated the sequence. I pulled the plugs and this is the first time they have nor been black and wet, They were grey and dry. Definitly a little leaner. I have not gassed up yet for the last 100 miles I rode. I will do that tomorrow and see what the warmer temps did for the fuel mileage.

You mention plugs "grey and dry" they should be tan,light brown like a toasted marshmellow,grey sounds lean to me.Glad to hear it improved your sled,keep checking those plugs.

Good luck!

Is your sled stock? piped????

Anyone thought to put this on the polaris blog yet? Maybe we can get an answer from them? Is the ethanol content in Sweden the same as here in the US? This may be the reason they are not connected. Just thoughts, I have a 5 year warranty on mine so maybe I will check this out next weekend in the UP. I did adjust my oil pump and I don't want this to burn me down. My plugs are still very dark so maybe I am in the clear.

Dry and grey plugs means new pistons soon. Did you adjust your pump too?

Found this with a Google search:

"The European Union Fuel Directive (98/70/EG) requires a 5 percent ethanol blend but doesn’t permit a 10 percent blend. The Swedish government has petitioned the European Commission to allow the use of E10."

But that article was from 2001. Maybe Sweden was successful in thier petition?


I also found this article.
http://www.i-car.com/html_pages/technical_...06/082106.shtml

Doesn't really say much about Sweden, other than they're pushing E-85 heavily...no real mention of their "normal" fuel.

But it does seem that Sweden is definitely using some ethanol blends in their fuel as we are. Based on my quick research, I'd guess they're running E-5. In US most of us are running E-10 these days, though you can still buy pure gasoline in many places so it's unpredictable.

Hey Sweden guys, am I pretty close on my assumption? Do you guys know if your country runs E-5 most of the time? Very curious...

Ethanol based fuels will tend to lean out a fuel mixture, which would explain why Polaris set it up rich...maybe too rich. So if Sweden runs E-5 and they can safely go to this "different" fuel curve with the wire connect (which I admit to still being a little questionable on believing it's existence), maybe our E-10 fuel in the US could push it over the edge and cause it to be just a hair TOO lean? That would be bad. And would be a justifiable reason for Polaris to recommend this connection to sleds in Sweden, but not in the US. Just a thought.

Then again, if it was indeed going too lean, wouldn't that exhaust temp sensor pick up the high temp reading and force the sled into failsafe mode to protect the pistons? Isn't that how these CFI's are supposed to work?

I would LOVE to see a Polaris bulletin from Sweden about this stuff if one of you fine folks over there are able to get your hands on a copy to share. It would answer a LOT of questions.

in sweden no one drives the E-85 fuel, i think our fuel is like 92octane

I never thought it would be E-85...that's a totally different animal. I was asking about E-5. 85% ethanol (E-85) would not work in these sleds at all...they wouldn't even run.

But E-5 or E-10 (gasoline with 5% or 10% ethanol blended in) is very common in much of the world, will burn just fine in almost any vehicle of any age, and the ethanol blend has nothing to do with the rated octane. Here in the states we commonly find octane choices ranging from 85 to 94 at the typical fuel pump, depending on what part of the country you're in. But much of it is E-10, or it might still be pure gasoline (without ethanol) in some select states and counties...but that is becoming increasingly rare.

I'm betting that E-5 is in your pumps...and you may not realize it. But obviously I don't have a clue other than the articles I've found on the internet about how Sweden is trying to be a world leader in eliminating/reducing fossil fuels, and ethanol blends are one of many steps they're taking because it helps the fule burn cleaner than pure gasoline would. But those of you who live there would certainly know much better than I would.

How about Simnil? Do you have any idea if you might have a little ethanol blended with your Swedish fuel?

Guys, please read this carefully!!!!!!!!!!!!
I have a pretty good relationship with my poo dealer and I asked him about these wires. In fact they DO! lean out the sled to account for no ethanol but it also comes with a reflash. If you do this witout the proper reflash OR! you are running a slp pipe it could be very devastating to your motor. They are looking into possible reflash options and he told me to hold off prob to mid summer to next fall.

It would be neat if polaris industries would comment before they have a ton of 07 and 08 warrenty work. Very easy to cover up by unhooking the wires. Most dealer tech's don't know how to use the full features of digital wrench to check the history of the sled. One of you guys go post this or maybe the moderator would give us their email and we can ask ourselves?

I agree that gray and dry plugs are an invitation for future problems. I will disconnect the wires and wait patiently for Polaris to come out with a fix. My 08 700 Switchback has the stock pipe. No mods to the intake air tract. Stock air box. I run regular gas not premium. I am running the standard Champion plugs. My oil pump has been leaned down. I am running semi synthetic Yamalube 2S. I have run this oil in my last 3 sleds with out a problemm 6K miles on my 03 F7 firecat at aproximatly 260 miles to a quart. My 07 Dragon 700 for 4K miles at approximatly 260 miles to the quart. My 07 Dragon averaged about 14 mpg. My Firecat 15 mpg. My present 700 13 mpg and 260 miles to the quart. Both my 03 Firecat and my 07 Dragon had light brown plugs.

well running the premium fuel would have changed the color of your plugs to a light brown, however I don't blame you for waiting , but this is very interesting find and I hope Polaris can input some info on this matter.

A local mod shop owner is complaining of all the sleds(most stock) he is seeing burned down cause of the amount of ethanol in our fuels. He states they are running lean cause of the ethanol content. Makes me scared at the local pump cause I am running cut heads for premium only fuels in my 2 mods.

Yes we do have some ethanol in our gas but not much, 2-5% or so, I´m not sure. Confusingly we have a different octane rating here, im runnning our 98 octane fuel which is the best available from pump, like your 92 octane or???, my favourite web site had no answer: http://www.convertunit.com/

Some people here not living close to a dealer are running the wires connected without the reflash, no idea if it is recommendable or not.

Took my sled for a spin last night and I´m still amazed of the difference, this is making me a bit pissed though, that they waited untill there is just a few weeks left of the season before fixing it. Will pull my plugs tonight and see how they looks.

I´m by the way running a SLP Single with can on my sled, If I have nothing else to do some afternoon I will change to stock pipe and see what difference I may notice now when the engine is running as it should.

Well...let's hope Polaris makes a similar reflash available in the states before next season. At least we know something is possible. Following is stolen from Wikpedia, regarding Octane rating methods. Europe uses RON ratings for display on fuel pumps, wihle US and Canada use R+M/2 ratings. Very different numbers. Approximations: Our "regular" 87 equals your 92, and our "premium" 93 equals your 98 octane. Thanks Simnil for sharing your thoughts on the 2% to 5% ethanol estimate for fuel in Sweden.

"The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing these results with those for mixtures of isooctane and n-heptane.

There is another type of octane rating, called Motor Octane Number (MON) or the aviation lean octane rating, which is a better measure of how the fuel behaves when under load. MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, a higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern gasoline will be about 8 to 10 points lower than the RON. Normally fuel specifications require both a minimum RON and a minimum MON.

In most countries (including all of Europe and Australia) the "headline" octane that would be shown on the pump is the RON, but in the United States, Canada and some other countries the headline number is the average of the RON and the MON, sometimes called the Anti-Knock Index (AKI), Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2. Because of the 8 to 10 point difference noted above, this means that the octane in the United States will be about 4 to 5 points lower than the same fuel elsewhere: 87 octane fuel, the "regular" gasoline in the US and Canada, would be 91-92 in Europe. However most European pumps deliver 95 (RON) as "regular", equivalent to 90-91 US (R+M)/2, and even deliver 98 (RON) or 100 (RON).

The octane rating may also be a "trade name", with the actual figure being higher than the nominal rating.[citation needed]

It is possible for a fuel to have a RON greater than 100, because isooctane is not the most knock-resistant substance available. Racing fuels, straight ethanol, AvGas and liquified petroleum gas (LPG) typically have octane ratings of 110 or significantly higher - ethanol's RON is 129 (MON 102, AKI 116) reference[1]. Typical "octane booster" additives include tetra-ethyl lead and toluene. Tetra-ethyl lead is easily decomposed to its component radicals, which react with the radicals from the fuel and oxygen that would start the combustion, thereby delaying ignition. This is why leaded gasoline has a higher octane rating than unleaded."

Any more word on this guys????

Here in minnesota we just got an average of 1.5 feet of snow last weekend so i went out. i put 92 octane non oxygenated ethenol free in and i tryed the two wires. first off you dont have to take the cover off. all you have to do is take the side pannel off and it is right next to your gas tank cowel in the cluster of wires down there. but i tried it for a while and i did notice a little more pull off the line but it wasnt too significant. i ran for a while and then checked my plugs and wow i was very lean so i would beware of doing this without the reflash.

one thing i was wondering is can you hook an inline potentiometer onto one of your EGT wires and be able to richen and lean out your motor with that. i assume the EGT gauge runs off of Ohms and if so you could change the resistance coming from it to trick the motor and dile in your fuel ratio. juist a though not sure if there is alot more to it than that or not.

Doubtful that changing resitance in the EGT sensor would do anything. I'm pretty sure the EGT data is treated only as a fail-safe, sort of like an on-off switch. If it gets beyone a given number of degrees (or resistance drops to a given level), the computer suddenly dumps in a bunch of fuel and/or retards timing as needed to cool the motor before it burns down. It's not really used as live variable tuning data.

I'd think more fine-tuning success could be had adding/removing resistance to tweak the data put out by the air temp sensor and/or the barometric pressure/altitude sensor.

That's probably part of what the Boondocker does...but I don't know for sure how those boxes work and what data they use. There's also a cheap product out there called the "fooler" that does just this thing by putting a simple rheostat onto the air temp sensor data...it's available for EFI Cats and early 900/700 CFI Fusions. Several people here have used them with success. But the company that makes those doesn't offer it for the 07 and later 600/700 CFIs. I don't know why.

I don't have enough knowledge here to be willing to sacrifice my motor by building my own electronics. I'd want an EGT sensor if I did, so I could have on-the-fly data to tell me when I've pushed it too far. If I want to do something like this, I'll just buy a Boondocker and play with that. But it sure would be nice if other aftermarket companies could offer alternatives...plug and play "chips", less expensive reprogrammers, or send them your ECU so we can reprogram it type of things. I'm not sure why such things are not offered more in the aftermarket for these sleds. I'm guessing these ECU's must have a tough code to crack...or maybe there's simply not enough demand to make them profitable.

Any new info on the pink wire or a reflash since spring?
