Silber and Boondocker Owners Wanted!!! Money Back Guarantee...

Because you have a ecu designed to be run with boost. When you piggyback onto the stock system, it might run at one elevation and temp, but as things change the stock ecu will change fuel and timing curves. Then you are fiddling with the box again trying to set it so it runs like it did before. Most people, including me don't have the patience or know how to always fiddle with a box when I could be riding. This Vi-pec, once dialed in, will be a pull and go sled. Once that happens, as was said before, many more people will want boost on their sleds. That will be the game changer. Vi-pec isn't some Johnny come lately fly by night company. Look them up once and see what they have done in the automotive industry. It is proven on the Poo, just can't wait for the Cat one to be released.

Absolutely to the point. I agree. I have had a few turbos, and while I can "tune" them, ie. adjust the boxes, I am at a point where I don't want to mess with it anymore. I want to ride, not tune. A few years ago turbos and on going tuning were synonomous. Couldn't have one with out the other. The turbo game has changed a bunch and I feel we are at the precipe of the age of turbo 2 strokes that are pull and go. The 4 stroke game has been there for a while, it is the 2 strokes turn now.

Nice to see people thinking outside the box and developing new technology that will better our addiction.:face-icon-small-hap:face-icon-small-hap

I have researched it, I have some vi-pec software on a few pcs, I am saying that this is a challenging project. I am not saying it can not be done. You are not dealing with some boosted race car here. Find me another power sport that runs in such a environment changes, couple that with a engine platform that mildly tuned naturally aspirated can melt a hole in a piston. No o2 feed back for the ecu no MAF. The volumetric efficacy on a 2-stroke is not as solid as on a 4 stroke. I just don’t see the feedback here from the end users and I mean not some one that rode it one day. Look at the boost it set up and the posts on it. I am all for a standalone ecu and understand what is involved in bringing it to the boosted sled 2-stroke arena. Than again I can be wrong :yo:

My M800 OEM Kokusan denki ecu handles all the riding condition changes I can get into. It also handles the unstable VE on my 800 2-strokes engine, without MAF or O2 feedback.
There has been EFI on sleds for 20 years now. I don't see what should be Vipec's problem making an aftermarket ecu that works as good, or better then the stock ecu that sits in the sled from factory.
It's not rocket science.
And about tuning each sled individually, that should not be needed eather. I would love to se the AC EFI engineer rocking around on each sled that comes of their line, tuning them individually. If that was the case, we would still be running carbed sleds.
If the turbokit is made with high tolerances, one map should fit all sleds with the given kit.

Wonder why MCX are so pop in the yammi world? I guess it is because no tuning is left to the sled owner. Bolt on, and go.
Vipec will prove that this also will be doable on 2 strokes.

What HM turbos can't do anything about, are those guys that think they can do something better on the kit, and chenge it's design. That be another y-pipe, another reeds etc. Then yeah, ecu will be out of tune.
Some people thinks it's more fun riding and just do maintenance. For those, vipec will be better then any piggyback.

park that beast in a wheelie and molest the throttle all over the place. WOT is easy, i wanna see flawless transitions in and out of boost under load... its hard to do, lets see what the vipec is made of!

I hope we got some vids like this that you can see. Snowing and cloudy:photo:
This sled is running very well. rode all day did not open a lap top on it once.

cody has the vids. I feel the silber kit is good. We have a couple more going out then we will know for sure.
 
Only problem i see with this kit is this. My boondocker kit runs pretty damn good if i do say so myself. Is it worth $2000 to run just a tad bit better? Thats my dilemma. Guess id have to ride with one vipec tuned first. You guys need to come to Cooke. Snow is deep and the trees are fun.

if your sled is running great then leave it. the options that we will add for you is this. complete control!!

Everytime we go out I learn something new. Or find something that we have control over and how we might change it.

Dang we are even thinking we could do traction control with boost. :loco: haha.
 
Everyone, I've been slammed lately and haven't had a chance to edit any of the Go Pro videos from the other day. I've got some iPhone footage that i just quickly uploaded on my Youtube channel. Honestly my entire day was devoted to another customer and tuning their sleds. So we didn't have much time to mess with the Silber kit on this outing. And really we didn't have to mess with it much. I just turned the boost up a couple of lbs. and let it rip.

We had a completely different conditions than our first day of testing and I didn't even get the laptop out once. There's still a few logs on their I need to look at. Our elevation changed about 2k ft, the temperature was warmer by 10 degrees, and it was snowing.

I can put more and more videos up, but eventually it's just going to be showcasing the same thing. The Vipec will work on ANY sled..........turbo'd, supercharged, nitrous'd, normally aspirated, lake racer, mountain climber, flat lander, European **** star, it even works on French Canadian sleds :) :). Barometric changes, weather changes are all compensated for. It'll give you complete control of all functions and then some, data logging, etc. You just gotta make sure you got the right guy doing your mapping that can meet your needs :yo:. Most of the more advanced features haven't even been shown at this point, but all in due time.

I'm going to take this out for one more ride this weekend most likely and then it's ready to return to the customer.

I'll work on uploading the Go Pro footage later today or over the weekend.

Thanks for all the support so far!!!!!! Lots of positive, emails, PM's, phone calls.

Pretty sure one of the videos shows this now.......thanks for adding that to our list!

i wonder if he is talking about me :canada: ?? Keep up the good work guys.
 
Well it is starting to snow now anyway. Thanks again Cody. Appreciate your work. Hope this weekend brings good riding. I think I'll take my 2013 Pro out and see how the driveshaft holds up. :face-icon-small-hap:face-icon-small-coo

Looks pretty nice, what level of boost are you running? also elevation (approx) was that hill at?

The hill was about 8500. the boost started at 6 psi and ended at 8 according to the 3 bar sensor not the boost gauge. boost gauge siad we were running 12psi.

Get that old girl to around 10lbs.

Thanks guys

It was never at 12......lol

Excellent!!!!!!!!! Looks good. I am ready for it. I rode my Tapex this past weekend with the 174" and my oh my I forgot how much work it is compared to the Pro. Pulls like a freight train, but feels like it weighs the same.:face-icon-small-ton:face-icon-small-ton

Maybe I'm just too old.:face-icon-small-hap:face-icon-small-hap

I'll be in touch.
