If you are running a MPI Supercharger

[stingray719]

i know what i learned...i buy a new sled...put a bigbore in..new frt and rear aftermarket skid...etc etc etc etc...

Why the heck didn;t i buy a used sled..!!...all my upgrades would have talen care of any issue a used sled would have had..

The savings buying used would have paid for a good portion of my aftermarket..

Dang...

I did that, bought a 2010 Nytro with MPI big supercharger kit from a shop in Idaho. Paid about the same price a a stocker would have cost me, as they seemed to hav about every setting you could imagine set wrong.....lol.

After getting everything set right and the addition of a Mountain Tamer skid I love it. Only MPI issue ever is having to set the GEMS often as altitude changes, will this new flash help with that? And does everybody else find you have to reset the GEMS often?

My stock Nytro that the girlfriend now rides we lightened to 541 pounds wet. Supercharged Nytro has most of the lightening but is still at 600 pounds wet and it is sure noticable but I am not gonna spend all the money to try to get another 25 or so pounds off. Friend with Polaris Pro was stunned to see my non boosted Nytro was about same weight as his Pro once he added his extra fuel cans to the tunnel.

I know Yamaha is not in the business of making money on snowmobiles....just farming for motorsports customers for the other Yamaha products but,

If they added boost and dropped 100 pounds on the Nytro imagine what a game changer that would be?

Look for the new 2014 Nytro next March....

Look for the new 2013 Nytro next March....

uh u mean '14 I assume...

 

[christopher]

Isn't that what I said ?

 

[bdoe22]

2014

I sure hope they pull their head out of their azz for '14. As a dealer, it is difficult to survive on 4-6 sled sales a year....turbo or not they need a new chasis.

 

[christopher]

Should be a whole new Nytro come march.

MPI Supercharger

I want to get back to the original question. Has anyone got their sled refashed yet.. My only complaint with my MPI supercharger is the stumble between low and high rpm's. As soon as they are reflashing them I wil ltake mine up.

 

[christopher]

I just fired off another note to Evolution asking for an update on the ECU upgrade for the MPI joint development project.

 

[SEAKRX1]

Following this thread pretty closely! I'm looking at a leftover 2011 demo with MPI Supercharger as I type this. Maybe I'll run the old rx1 one more season and see what Yamaha does next year. Not interested in spending 10g's and not have it run right.

 

[paulharris]

i must say its hard to believe that MPI has been building supercharger kits for so many years and they still don't have the fueling figured out, i hope you can get this thing running right for next season.

 

[christopher]

Got this note back from them this evening.

Hi Christopher,

Thank you for the check in. Progress is being made!!!

Best regards,

Jim
EVO

 

[smwizzz]

Yep....

I would say MPI will make it right. Not much I have heard bad about them. Still there are others out there who can make these systems work too. I would guess at least 50% of the turbo peeps here have done like me and changed untill we found something that works.

I switched up to Boost It on a turbo. My bud did a Boost It on an MPI last winter. Time will tell how his works... MINE is AWESOME~!!!

 

[christopher]

Ya, seems strange after all these years that they don't have it 100% dialed in by now

Christopher the Evo guys are going to blow you away. What is probably going on is as they dig into the tuning they are finding way more things they can make better than they originally thought. They have probably also found areas they can upgrade in hardware too that will unlock some tuning opportunities. Firmly convinced there is no one in the sled world that brings their level of professionalism to the sled world. If that supercharger will support higher horsepower levels you will have some upgrade options too. Get ready to be AMAZED! lol. You are going to love the finished product.

 

[christopher]

From the time that I spent with them at St. Anthony Sand dunes a couple moths ago I came away with the same impression.

They boys KNOW what the heck they are doing when it comes to boosted tuning. If they are able to translate all of their Automobile knowlege and apply it to the sled industry we will be in for a VERY PLEASANT surprise.

They are doing it for the Artic Cat now, and we are just waiting on the YAMAHA version...

Product Details

The EVOPS 215 hp 91 Octane high elevation reflash was born on the mountain. ALL testing, dyno work and tuning has been done in Steamboat Springs, CO or in the mountains near Salt Lake City, UT. The Arctic Cat/Suzuki/Denso ECU has many features built into it from the factory designed to make it operate within a very narrow hp range. While others have been able to make big horsepower at sea level, only EVOPS has been able to overcome the factory programming to make the big horsepower at altitude. Our tune has been dyno verified at 8000' elevation and proven on the hill. All factory protections have been left in place and/or enhanced. The rpm limit has been raised to 8500 along with the knock sensor threshold. Over 200 hp is available for a 1000 rpm span! Other runability and drivability changes have been made as well. The engine idles better because we have raised it and made it slightly richer. We have also lowered the cold drive away threshold so you don't have to wait 5 minutes to move the sled.

• Merchant SKU: EVOPS-IT-ST215
• A true 215 horsepower at high elevation
• 91 Octane
• Knock sensor rpms raised to match new rev limit
• Over 200 hp availble for a 1000 rpm span
• Idle raised and smoothed
• Cold rpm limit changed so you can move the sled sooner

I know this may not matter because I don't have a Nytro, but I have a MPI supercharged Vector with 9,100 miles on it. I have had ZERO problems with the MPI kit. I did go through my first set of pulleys last year and MPI was great about helping me out with any questions i had. Granted I don't have to mess with fuel numbers because it is carb but Love it still the same.

 

[christopher]

Well, I got my supercharger put back together last night.
So all I am waiting on now is the new ECU upgrade.
Hope to see it by the end of September!!

 

[ruffryder]

Hope to see it by the end of September!!

We should make this a poll to see if people think you will have it by the end of September... lol

 

[christopher]

He he, not a clue on that one. Sure hope they are done before the season begins though

Any word yet on the ECU re-flash?

I noticed on MPI's webpage that they can re-flash factory computers, including the Apex and Nytro.

Very interested in this.
