I thinking about having Jeff at dakota performance put on either the Push RG kit or the OVS tial RG turbo kit. Turned down to pump gas to begin with, and later when I get use to it turned back up for RG. Now here is the catch. My usual riding partners are my wife, brother-in-law and his wife. We all like riding off the trail but the places we ride (mostly west yellowstone and the black hills) we end up riding quite a bit of trails to get any place to play. Now will the two kits that I have been looking at work for riding that much trails?
 
the problem for trail riding with a turbo on an m8(any two stroke) is the efi box(piggyback) is not capable to adjust fuel delivery in a stable way. i have a t-rmk-iqr-t(700),t-m1000....2 attitude boxes and one boondocker and it is not possible to ride half throttle for a minute straight(will go lean then fat then lean then.....burn piston or cooked motor! what ever comments you will get on this forum or elsewhere, all turbo kit are good(pretty simple to put together) and all of them are trail friendly but..........there is no E.F.I. solution at this time that will permit you to drive a ``normal trail`` day like 100 miles. with a two smoker, it is on and off throttle all the time....full throttle ok but mid to 3/4 steady??impossible. i'm working right now on a complete standalone e.f.i. unit so we will be able to 'normaly' drive these machines.....should be available this winter for artic cat and polaris....keep coming!
 
Supra is right. Around half throttle is when the timing is at its highest i believe and the engine is producing a ton of heat, this is shown through the EGT gauges and not through an AFR gauge. If you were to do the turbo I would run minimal boost,5 PSI, and maybe av gas to keep'er burning cooler. When you get to the play area turn up the boost and have fun. Hell, 5-6 psi is still a blast, tons of power!! Any thoughts on that from the experts?

standalone ECU with turbo support already exist for arctic cat. for Polaris i am not sure.

there are few m8 with turbo, running a standalone ecu. with direct wideband, boost controlling and diff maps and lean out protection

i hope they have a name, i got one of those boxes from a friend

they build i think 20 boxes for testing.
on the box i have here, the map sensor and the wideband sensor are on board.

there is no market for that kind of products here, so i am not up to date about the actually status.



Do they have a name?
 
I am sure if you could find out the name of the company, many people would be interested. Infact, it may help with the companies lack of a market.
 
You are keeping this very vague dude. You've got a computer screen shot in your post and you don't even know the name of the guys who created the unit? If there are only 20 or so of these boxes out there then you must know something. Are you able to find out perhaps? I am all about this kind of stuff, ask supra, I am totaly stoked about the technology he is working on.

How did you acquire this box? Can you elaborate on "I got it from a friend", please?
What did it cost you?
How much boost are you running with this box?
How long have you been running this box?
How many kilometers have you run with this box?
What elevations are you riding at? Lowest to highest in a typical day?
Are you seeing good results with this box?
What grade of fuel are you running at what boost with this box?

I'm not trying to be rude but we are not mind readers here. You can't just say "hey I got this sweet box that already does all of that" and then say nothing more. Come on man give us the goods bro!!! LOL
 
Maybe he can't say more?? Allot of guys on here are testing products and are under order not to tell or give out to much info. Maybe this is not the case but many times it is. Will be interesting if it hits the market.

As far as down the trail yes I do get more heat at 1/4 throttle but trail rides can and have been done allot. Just blip the throttle here and there or if you are very worried about it fatten it up a little and hold the throttle as long as you want in a set area.

Subra you say you cook motors with the piggy back boxes in 30sec. I have held my BD Dragon with BD settings and wile it did get a touch hot (not lean-then rich then lean like you say) I held it at 1/4 1/4 and on smooth trails 3/4 throttle for way more than 30sec and no problems at all and wile I did not count the seconds I know it had to be in in the 2 min range.

the project is still somewhere on the bottom on our TODO list, so there are not so many information's that i can tell you. As i wrote it before, tests need to be done and actually there is no time and money to do that.

if you quarantine me to buy 200 boxes i will move that project to the first position. :face-icon-small-hap

SNOWJW posting is correct, we have BD RMK and M8 snowmobiles in our area and they do a lot of trail rides, i never saw any problem on any sled with leaning out. the magic word is "setup"

You are keeping this very vague dude. You've got a computer screen shot in your post and you don't even know the name of the guys who created the unit?
I do, but there is no reason to tell you more information

i do, but as i already wrote it is not a #1 project
Are you able to find out perhaps?
yes
I am all about this kind of stuff, ask supra, I am totaly stoked about the technology he is working on.
it is one thing to work on it and it is other thing to sell it and to give a 100% support to customers

How did you acquire this box?
I own a company for automotive research and development we have our sources to get that stuff.
Can you elaborate on "I got it from a friend", please?
friend is mostly a guy who is a enthusiast and has contact to people doing electronic work
What did it cost you?
all ECU's cost +1000 USD, material and development are expensive, it is a worldwide standard.
How much boost are you running with this box?
Box has internal map sensor up to 3bar, that is enough for every rocket you want to build
How long have you been running this box?
20 hours on M8, 10 hours on 700 rmk, 2 hours on z1 (i like the z1 setup but techican people are expensive so its slow development
How many kilometers have you run with this box?
on m8 200 miles, on rmk 20 miles on z1 500 meters :-), i have problems to find snow in summer,
What elevations are you riding at?
sea level - 5000 ft, no higher mountains in my area
Lowest to highest in a typical day?
2000 - 4000ft
Are you seeing good results with this box?
the box controll everything like OEM box, all other is "tuning" it depend how good you are in "tuning"
What grade of fuel are you running at what boost with this box?
we have only 98 and 102 octane fuel, hard to get av-gas or vp stuff

I'm not trying to be rude but we are not mind readers here.
You can't just say "hey I got this sweet box that already does all of that" and then say nothing more. Come on man give us the goods bro!!!
my market is europe not US, if we decide to sell stuff to US you will be able to get more information, it is simply stupid to give more information as we should.
LOL
