WKM Evolution Big Chute kit vs 1.9 and 2.0 video from Vale

Gene, we're you impressed with how fast the BC was and how well it was tuned, right out of the box?

I was hoping for a sled that has stock characteristics in throttle response. I was maybe not suprised how good it was because I expected it would be in talking with Jim over the last couple months.
I was suprised how fast it was in those snow conditions with that track. It wasnt blarringly obvious until I raced the 1.9. It was almost twice as fast but its also making 9-10lbs more boost so it makes sense. Also very impressed with the lack of lag in the drag racing. I didn't feel it in trees, really easy to ride. For the price it is the biggest improvement u can do with the most results. Smaller wheel for production will make this a non topic. Great product.

I would now like to get some time against other iron I am familiar with.....
 
Nice work! Do the head studs need to be upgraded? What kind of power do you get from the BC kit on pump gas?
Do you have a number for the whole kit installed?
Sorry if I missed the answer about power..

hey guys,
the reflash solution for the 1100t is very commun within the groomed trail sled community,very recent for the mountain guys.....
we have a lot of z1-f1100-pro climb 1100 installed with vi-pec standalone ECU(in fact, we are coming at haydays(on display ) with a new plugin ECU for the 1100t ) and i have seen a lot of 250 hp claim ,when engine dynoed, they were in fact 210hp 3 second peak hp(like some dynotech videos!!!) falling off their face at 190 hp right after(not shown in the videos!!)......are you flashing the ECU yourself or are you buying/using speedwerx/turbo dynamics/boost engineering reflashes? there is not too many solutions/softwares existing to 100% extract all tables from this denso ECU....all reflash solution in north america are developped by this retired denso engineer(won't say his name!) and it is only modifying a few tables inside the ECU. we are able to extract every single byte from this ECU (100%) and reflash whatever inside it, BUT it is not in our opinion, a viable solution simply because it is a static reflash solution(not like cobb pro tune for subaru let's say) and does not offer near the motorsport options and flexibility of a true standalone plugin ECU....i want to hear/see more of the reflash solution you are offering the crowd and who is the tuner behind the scene(you can pm me if you want or email, doesn't need to be public).... i have a lot of horror stories to tell/show with reflashes for the last 3 years, not saying your solution is a bad solution at all, just want to inquiere more so people here can understand a tinny bit more what.s being offered on here.

this is a 510 hp (not peak hp but steady hp) asphalt drag race 1100t we have installed with one of the vi-pec standalone and cdi unit . next standalone ECU will be a true plugin 1 to 1 replacement(september) with 100 factory dash working(exactly like our 2 stroke ECU).

Reflashed themselves, if you wanted the name you would have just PM'd. Their credibility is in their products and this isn't their first go around...
Evolution Powersports = Evolution Motorsports = EVOMSit "Intelligent Tuning"

not to disrespect, but the questions weren't directed to you. i know what they do, we do same stuff, so is unitronic,boost engineering,turbo dynmics,Cobb,ecutek and a multitude of other companies.....just not specialized in snowmobile. i asked a few questions just so they can clarify a few things for the masses....i have never jeopardized their credibility and it wasn't my intention.it is good to see other companies jumping aboard!
 
It's not my place to answer this post, I'm sure Jim will reply with as much information and detail as he deems necessary. I can confirm this is an Evo developed tune. Without any disrespect to other reflashes this is not another companies code "massaged" or "modified" to call their own.

I have ridden many other trail/lake based kits in the past years and they all claim big hp numbers, and you are exactly right, there has been a lot hoopla and lots don't deliver what they say on the hill.....and the hills are where we ride out here. Until I ride otherwise, IMO this is the best tune and kit for the M1100....and I can say that knowing it's not the only tuner/reflash i sell in my shop.

thanks for clarifying.I have seen numerous dozen of guys ending up paying 4-6k in repairs for badly tuned novice reflashes ....(speedwerks and d&d are the worst for sure). Evoms and turbo dynamics seems to be in another league and the only real test is how they are handling the altitude compensation tables on a snowmobile because it is a complete new playground for them. those small 4 stroke engine in the sled industry are stupid simple compared to automotive engine technology.....hoping they are here to stay! good job guys.

Our tuning is 100% our own. All ECU tuning, dyno work and field (mountain) testing has been done by us and our dealers. We have full access to the ECU and can change any and all maps necessary. We have also developed our own flashing hardware. I do not know the "retired Denso engineer"

Our ECU calibrations are matched to the turbos we are building for the 1100T. In other words, the Big Chute program is not the same program as the Super Chute, even though they are similar sized. Our stock turbo high altitude program is also 100% custom.

For people who think they can and want to do their own tuning, a standalone is great.

Good luck with the high altitude tuning - it is what separates the men from the boys so to speak. (keeping in tact the factory altitude/boost compensation) I suppose you could wish us good luck in the drag racing scene (which we have not entered yet). Our 500+ hp motor is being built as we speak...by the same employee that builds our Porsche motors... We are no strangers to going fast, we would just rather go fast up a hill than in a straight line on a snowmobile (for now).

See you at Haydays!

perfect.

Maps are preset for the turbo kit manufacturer we are working with.

we no more need a good luck wish!!!last year was a altitude compensation season!! we can now go from 0-13000ft and have much better results than polaris /arctic cat.
I suppose you could wish us good luck in the drag racing scene (which we have not entered yet).
Of course!

We are only tuning the racers (indy lite, gt touring,crc,ect.) we do not build hardware no more.

well, coming back from 2 cooke city trip in march, i can tell you we can go fast up any hills too!!(on some turboed 2 strokes).Wish you the best of luck for this year too.We can go realy fast too, but we are focusing on reliability as a priority.

See you at Haydays
sure!! we will be on display beside arctic cat USA with our 4 new plugin ECU , stop and say hello! we are not grass drag racing, we prefer snow and anybody can have a 600 ft fast sled holding up a few round, that is not realy impressing us no more.

again good luck and wish you the best.

p.s.: try to shave 150 pounds of those 4 stroke sled, in the mountains i found them horrible to drive compared to a zippy,nimble 2 smoker.
 
I can tell you from years of riding 4 stroke turbos in the hills it will take more than a couple trips a year to get your 4 stroke legs under you lol. Some guys out here ride 60-70 days a year.

For the most part this has always been the problem for the mountain riding segment that Jim and I come from, aftermarket performance companies that don't spend enough time on r&d with their product where it is intended to be used....on the mountain. I will take a tried, tested, and true mountain sled before I would take a dyno queen anyday. Making any of this stuff work at elevation is the key. Evo has an R&D shop to test, tune, dyno, and ride at 6800' in Colorado. They are there all winter. This is in no way a slight against Precision, I have heard/read good things about you guys in the flatlander sections of several forums. I am just happy that Jim and the guys at Evo have the same passion for mountain riding as the rest of us out here have.

Reliability is what Evo has build a tuning reputation on, no different than any successful motorsports shop. The BC kit video that this thread started with has been on the mountain being riden for over 5 months without any issues with the kit or motor. It is the most mountain tested upgraded turbo kit out.

As for lightweight...we have the lightest 2 stroke PC on the snow with our development of cf parts with C3 last summer. Everything we did to that sled can be done to an 1100. That was over a hundred pounds, which makes it the same weight as a stock M8...just with double the hp....or more:rockon:

Did you ride any M1100 with the kits you are developing in Cooke or just the 2s you were referring to? It will be great to have another product when you get it done, separates the wheat from the chaff that seems to plague the mountain segment everytime a new model comes out, regardless of brand.

I want to be clear that this is not flaming or bad mouthing the crew from Precision in any way. I never offer options on anyone's product I haven't ridin. What I am saying about Evo and their kits is what I know about them from first hand experience.

Cool.
Todd & I are both from Italian decent, but I think you are talking about is Mike - he is from Greece.
I know what you mean about the 2 strokes vs 4. It is a tough transition for a few days. After that there is no looking back!

Evo look like professionals and I'm glad we finally have someone that will give us a run. Although they do not seem to have 4 programs and other specialized code in the ECU that we spent nearly 100 000$ developping.

But our ECU has a lot of custom code not from the original ECU. Code that adds instant boost retard when knock occurs, not just timing retard like the factory ecu. We lowered temp warning.

Best of all we added a Knock light system connected to the diagnostic. Simple one plug and it will light up instanly when knock occurs. It is a 2 step with light knock lighting up and heavy knock flashing...

The factory octane code take a LONG time before coming on. It lets the motor take abuse before activating. These motors are very tough but constant knock will eventually hurt the motor. This is why we spent so much R&D and time to make it as fool proof as possible.

Now a customer can still abuse it on low octane and let it constantly protect and eventually he will hurt the motor. You have to use your head.
But if the knock light is not coming on, you will not hurt the motor. This is why guys feel safe to run up to 270HP on pump gas with our reflash while previous power levels offered by the competition were only 210HP.

The only reason we were brave enough to release that much power on pump gas was all our safeties.
This year we further improve the technology of the factory ECU with the new Stage 5. We always evolve...
