Anyone running a aftermarket ECU on their 700? What kind of performance gains do you see?

You will get varied answers, but I recommend the VDI Copperhead unit. This unit should be available in a few weeks. Lyle is the owner and designer. His product is awesome and his customer service is second to none. His test unit has been run against the Dynatek. They are getting a little better acceleration and 3-4 mph over the Dynatek. BUT, the downside is the VDI will be around 500 dollars. The Dynatek ignition will run you about half of that, but if you add the Dyna fuel controller as well, they come out to around the same price. The VDI will plug and play (replace) in your stock ECU slot. It is a fully programmable unit that you can tune to your liking for your setup. The thing I like about Lyle is that he continues to develp fuel maps and posts them on the VDI website so people can try different ones. He is still pushing out maps for the 700 King Quad (the first EFI unit he made) and it has been out over a year. He is also very quick to respond to anyone having problems with the maps or the unit itself.
Chris C on here has the Dynatek and seems to love it. I am sure he will chime in and tell you a little more about that one. It is a plug and play also, but it does not replace the stock ECU. It hooks in to the wiring harness down near the engine and fuel delivery system on the 700.

I have a denytek ECU on my 700. it is quite an amazing difference.
alot more low end power and mid range. removes all limiters
i have 27 inch tires and i can still run 52 MPH.
i got mine from hunter works it was about $220.

the VDI Lt is talking about should be nice to.
but it has the programmer built in. you wont need that unless
you plan to put a pipe on it and do extream mods.
I dont recomend a pipe of any kind if you woods ride. cause it takes away from
your bottom end, the VDI is $500 dollars.
danytek makes a programmer too. but it is seperate. and you can
buy it if you decide to go that rout.
Marty posted some test results from VDI , if thay'
are accurate. the Danytek will do more for you out of the box.

Chris.... Wink

The low to mid end is what I am looking for. Some extra grunt for trails and hills.

Why would something like the billet exhaust tip take away low end power?

Chuck

Subject: Re: ECU on 700 Tue Sep 16, 2008 11:32 pm

you need back presure for bottom end. you need flow for top end.
a tip wont hurt you to bad. just make noise. but a after market whole exaust
will breath more. and hurt your low end.... Wink

but will run better on top end. you dont need that. you need only low end on a rhino
for woods rideing.... cheers

in other words leave the exaust alone for the woods.... Wink

It is not taking you long to figure these rhinos out. Before to long, you will be doing the Rolex swap Tools

Ronnie its not just a Rhino ,
I know motors and i know how thay work... Cool

I also know how to make them Screem... Wink

and the main fuction and reaction of all combustion
engines are the same. and in all forms of raceing
or 4 wheeling there is one known fact.
You can not have a ton of bottom end power and a ton of
top end power. its just not possable , even more so in
a limited size. Now if you were talking about one of my
655ci DRC motors. ya you can have a pretty good bit of both.
bacause it makes 1600 HP and with NOS its about 2400 HP .... :D
so you have a little bit to work with. now on a Rhino with say 30hp
there ant much there to work with. so you got to put all your apple in one basket
so to speak. so its all top or all bottom. ... Wink

I my self
prefer bottoms. as it is a dirt machine. it is not a race car.
Now if you want to buy a big bore kit and stroke the crank .
now you can do a little bit more but not what guys at rhino forums
are trying to do. but over there its ok for top end. hell there in the middle
of the desert running wide open all the time..... Rolling Eyes

But for what we all do. you need bottom end power.
and the only way to get more is move more air and fuel in the motor.
and the will require a larger piston.

also just for the record. i wish could remember where i saw it.
someone has already made a 843 big bore out of the 700 , and got the
EFI tuned in useing a ibusa fuel injectors.
and with no power adders like turbo or nothing.
just naturaly asperated. thay got it running in the mid 70's..... Wink

I knew once thay figured this new EFI out. and made big bores
thay would fly.
all it takes is the know how and alot of money..... cheers
