I'm not a push turbo guy- but very cool

lcd only without case.

last row will be replaced, on a 2 stroke you do not need oil temp. instead we will have barometric pressure

there is also a LED for OIL F/E

Wyo you said you want to see what the ecu sees. I am not sure what branix's ecu is going to see but his optional display can show: RPM, MPH, BOOST, EGT, WATER TEMP, AIR TEMP, ALTITUDE, HP, FUEL, OIL, O2, TPS, INJECTOR DUTY CYCLE, MAP 1 or MAP 2, KNOCK SENSOR, SENSOR FAILURE, (taken from push's website.) With all this info it should be VERY easy to tell when you have a problem. But this is all based on the info for the prototype so we will have to wait and see if the production units keep all the features.

Dakota Performance has a picture of the prototype display.

big dash is not programmable, not for end customers, T-Kit manufacturer can add their logo on a start-up screen.
the powerbox lcd is programmable by dealer for end-customers (name, address, co** size, what ever)

lcd can show everything that ECU can do, engine info, sensor info, environment info, ...
BUT LCD dash is a INFO tool , not a programming tool, not a communication tool, it is what it is, INFO tool

i wish i can show you our lab, heated color LCD dash, gps, gsm, camera, 64gb storage, diagnostic, you can send direct files to your dealer from the top of the mountain, remote management, google maps tracking, engine recording, gopro interface, ....... sounds like modern cars?

Went and searched the push website and found more info, here is the link and info on the gauges, sensors, etc... my apology for posting about it without searching hard enough. Thanks S_P

NEW PUSH TURBO ECU (replaces stock ecu) with boost control, knock sensor, 2-EGTs, power valve control - opens under boost not rpm, timing, altitude compensating, Bluetooth programming, 2-different maps with switch on bar, 2 extra injector wiring, Totally programmable by PUSH TURBO.

Egts no mention of A/F ??? controlled powervalves- I was wondering about that and think this is sweet! Bluetooth- tell me more.

http://www.pushturbo.com/home.html
The ECU will support some stock dashes with RPM and MPH only. There will be a new dash available that is water proof, heated and visible in all light conditions. The dash is programmable by PUSH TURBO to display some engine functions, such as RPM, MPH, BOOST, EGT, WATER TEMP, AIR TEMP, ALTITUDE, HP, FUEL, OIL, O2, TPS, INJECTOR DUTY CYCLE, MAP 1 or MAP 2, KNOCK SENSOR, SENSOR FAILURE, PERSONAL MESSAGE WHEN STARTED,(ie. your name etc...) and much, much more. There will be ECU and DASH kits available for most existing PUSH TURBO kits.

says dash is programmable, but not that it will say it all, just how much info can you read on the dash/ or program.

Also said the rg kit comes with a I.C., would like to see it.

What about oil injection delete, which would take different programming.

More info than before, its a start, I'm still not clear on everything you said but from what I gather I don't care for the dash but want the lcd, Will the 2stroke also show A/F and egt's.
What about knock sensor it would be nice if there is a way to read 25,50,75,100% knock, I don't think it is that accurate so just asking?
could just run the old gauge for fuel pressure.

If there is a det problem will pull timing and then boost, both or how does it work.

At what point does it open the power valves, 1lb of boost or __lbs ???
I think that alone is going to help a lot with spool up and mid range det problems.
What is Oil F/E -

On the Polaris site there is a post by Precision EFI ...they have converted a Vi-pec box for the new Pro RMK and will be adding Cats to their list ....should be an interesting year.

www.vipec.com interesting stuff already making jet-ski stand alones....

To answer a couple of questions. No, the two stroke does not use AFR uses EGT for closed loop adjustments. You can adjust what rpm the power valves open at. You can also adjust the sensitivity of the knock sensor I believe. The blue tooth option allows a tuner to monitor and make adjustments from a cell phone or iPod/iPad remotely while a customer rides the sled (only dealers will be given software for this). Pretty dam cool.

"If this is accurate" and it can be adjusted with a phone then the app on the phone would be pretty simple. In other words I would have to have it, I don't think the turbo kit price includes them coming to MT to tune my sled, and knowing that its that simple I would be rather pi$$ed to be left out of the loop like the manufacturers have been doing for so long. The closed loop system is a program that give you access to all the stuff they wont and now they are saying it to, BS. I also thought PV opened on boost not rpm,

 

[branix]

the phone app make only sense to log the ecu and to forward the logs to your dealer to see if there is a problem.

On the Polaris site there is a post by Precision EFI ...they have converted a Vi-pec box for the new Pro RMK
We didn't convert an existing ECU(v44-v88) for this project, it is a totally new ECU only for powersports
and will be adding Cats to their list ....
Cats will follow end of this winter and ready for next year.
should be an interesting year.
of course !!!

Next week we will post engine dyno sessions/results and videos of an actual sled with all factory functions overidden by our ecu and some dyno pulls!! Also some pictures our our own intercooled turbo kit.

www.vipec.com interesting stuff already making jet-ski stand alones.
your link is corrupted i think (mignt be my computer too!!)

p.s. sorry for the little hijacking

A standalone ECU is a very nice tuning tool, but don't forget it is just "a tool" it is as good as the guy programming it.......and this is where we'll see who stand out of the crowd......E.F.I is not easy!!

would like to thank vi-pec and branix for taking the powersports indusrty to a new level and getting closer to automotive industry.

[WyoBoy1000]

I'm not sure but on the Push web site it claims a certain amount of hp at a boost level, and on pump gas. But at what elevation is it rated at, makes a big difference and also wondering if you can turn it up and down to peak boost on pump gas without having to retune.

 

[dakperf]

Just to clarify a few things,
We still think that the Dynojet Powercommander 5 is the best fuel controller on the market right now and we are still using it on most of our sleds. We have been talking to Brani Stojakovic of Branix and are very impressed with everything we've seen and heard so far.

The Branix standalone two-stroke ECU has not been tested, used, or sold to anyone in the U.S. yet. Brani will be coming to North Dakota and along with our team here at Dakota Performance we will be dyno testing the ecu on 3 different AC sleds both turbo and non turbo, one Push Turbo and one OVS turbo very soon. If we like the way it works then we will be available to anyone.

The Branix ECU is a two-stroke Standalone ECU for all two-stroke motors from different manufacturers both naturally aspirated and turbo charged.

Prices have not been set yet, we need to find out how easy it is to use before we will set a price for the standalone.

Overall, we are very excited about the potential of the Branix ECU and we want this ECU to be a bolt on application that will allow you to safely make large amounts of rideable horsepower with no headaches and constant tuning issues.

 

[SoDakCat]

That is my main question on this setup is that are the two maps set up for a select amount of boost for each map or up to each amount of boost for each elevation setting. I'm sure not everyone needs 14 or so lbs of boost and that could get out of control in a hury if someone is not use to riding a boosted sled.

 

[WyoBoy1000]

Dakperf,

Kinda what I was thinking, I think I will hold off on something like this to see if it works the way we all think it should or gets updates like BD. Would like to know what the programming options would be to install the ecu on another kit, as soon as you get a feel for it please let us know.

 

[turboless terry]

Sounds lik,to me, nobody will be getting a push turbo this fall.
What was the ecu tested on and for how long?
How long has the tbbt been tested and on what?
What is max boost on pump gas at 8000 ft.?
Does it automatically raise and lower boost, like boondockers ebc, when you go up or down in elevation?
Do you have to go back to the 09 head to run pump fuel? Hit the det sensor on my buddies 2010 at 9 lbs. at about 9000 ft. with straight av. In and out of it in the trees it was fine but on a longer pull it would hit the det with the 10 head.
Need a turbo for my new cat. Don't want to wait forever but I don't want to be a guniea pig either. If it hasn't been tested here I'm sure you don't have a clue when it will be released. I guess I should ride my new cat and make sure I like it first since cat was kind enough to not let hardly anyone test ride.

You do have a lot of questions, and so few to answer them. I do feel sorry for you.
Here is how it is.
Push will offer his kit whit a OEM ecu. Which means that you wan't be able to do any changes on it yourself. The idea, is at it should work as on a stock sled. Stricktly there is no need to tune a stock sled?
But, I bet you still can hook up a BD box if you still feel for making it better on your own.

Option two, is a full programmable SA ecu, which are not sold as a part of any turbokit, atleast yet.
If you buy that SA ecu, you can look at yourself as an Arctic cat enginer, playing areound whit the laptop, mapping until your face turns blue.
I've seen the software, and software is as good as it is for any other SA on the market.
If you have the knowledge, you buy the SA. If you want to ride, instead of playing whit the mapping all day, you buy the kit whit the OEM ecu.

Have you ever seen a yama dude playing whit the MCX box all day out riding? Guess not (there's no buttons). And that is the idea of this new, and gamechanging product.

And this is how it will work. If you don't have confidence in the turbokit manufacturer, or don't like the idea that you cant be the master tuner, then buy another kit, or buy the SA ecu.

 

[sweperformance]

I don`t really agree with you. I have not touched the attitude box after adjusting my sled i the dyno, riding for two seasons.. But I understand the concept push looking for.
Is it possible to get more info on the fully programmable SA ecu, What kind of software? Fully adjustable ignition timing?

My friend.
You and I now well how small elevation changes our sleds are expnaded for. That is why we don't need to touch our boxes. I doubt it is beacause I've made such a good tune on it
Software is made by the producent. Branix. It is not fancy looking like alot of other programs, and there's no reason it should be eather.
It has all function what you are looking for.
You can even set it up using it for "out of spesified" sleds if you figure out the wiring.
Everything is fully adjustable. All PID controlers needed. Ign, fuel, boost table,idle control, load map, 3D graph etc.
When you buy a SA, you start whit blank sheets. That means everything has to be possible to edit.
It is amazing. Not only for the turbo guys, but all of us that run really piped sleds will have a huge advantage in a product like this.
It is basicly like an automotive SA program, but whit spesified function related to snomobile.

 

[mynewuseddoo]

Swe, can you please explain how you don't have to touch your Attitude controller ever please?

With temperature change I have to adjust my Attitude box going from winter to spring and then into summer. I'll end up pulling almost a full 8 lights of fuel going from the coldest day that I see to the warmest day in the summer or I will run pig rich 10 AFR and cooler EGT's. When the ambient temperature warms up and the air density decreases, I notice it on my EGT and AFR a lot. If you're not touching your fuel controller once in a season then I am thinking you're going to be running rich during warmer weather. The ADA on the Boondocker box helps with this I believe, not 100% sure though. As far as I know, the attitude fuel controller doesn't compensate for this, as seen by my gauges.

Do you run AFR or EGT gauges?

 

[WyoBoy1000]

Like efi live but it sounds like it will be way more $$$. The way you talk daltech is the kits on the push website that pretty much give you the idea your getting a SA kit is not a SA, WTF?????

What I am now wondering is if you buy a regular kit and then the SA ecu, Is there any way to pull the stock mapping off the stock ecu and program it into the SA ecu. (pretty sure I know someone that could but may not be legal) then I can leave the kit alone with the piggy back system still in place, but I can go in and make changes like timing and powervalve functions. I get the basics of this system but would have to be hands on to figure it out.
Am I capable of tuning it, yes, but it may take some time, although if I can do what I stated above I can still ride instead of spending countless hrs tuning and just tune as I go.

This kit push is supposed to have based off of there website will take at least a year to establish weather it will work or not, if it does they have one more year before the entire engine platform changes with the cats. This would be the other advantage of running the ecu programming in the SA ecu, you can just make a few small changes and as they figure it out more and more it will be easier to copy or buy the programming from someone else then spend all the time doing it yourself. Much like racinstation has done with the the PCV, then you have a really good starting point and can make small changes if needed.

Like I have said many times, while the 4 stroke plug and play systems work well, the 4S motors are predictable, the 2S is not and there are probably only 5-10% of people that actually work a 2 S to its max, I have trusted others before and it has failed, when I tune, even if I can't adjust everything I know what is going on and when something has to change even with the limited access I have, but I keep them running. So to come out with such a great tuning tool and limit access is just straight up back words to me.

It also seems some people talk like they know what is going on with push but its all contradicting itself in some small ways, that scares me. I like what I see but the info is not straight yet, (reminds me of bd and slp, just out to sell it and then prove it) to everyone that is working on this system, keep it up it looks very promising.

Do you run AFR or EGT gauges?

one way to do this is with a closed loop water to air intercooler. ambiant air temps have little effect on charge air temps when they are always ice cold

 

[mynewuseddoo]

Ambient air temps will affect the down stream temperature of your intercooler to some degree. Mid winter air at -15C to spring/summer riding at +20 will affect your intercooler final temp quite a bit.

The liquid N2 plant my guys run uses a chiller to bring the compressed air temp down to around 7C with an inlet temp of about 18C. If I increase the inlet temp up to 23C, I can see an increase of about 2C after the chiller. The chiller is a compressed freon heat exchanger. I'm thinking that little intercooler with warm water flowing though it is probably going to show larger temp variance than what I've seen with a freon heat exchanger. The actual temp change with ambient might be a little more than you think.

You will definitely have cooler temps than I will ever see though. No intercooler, friggin straight piped lol!
