Chk out PRC fourm, soom one remove a ring from the cluch area and it mkes the RZR go over 70 mph WOW ;-)

 

What do u think about the ECU idea?

 

Great tuning option! I bet it wont take long before there is a plug and play stand alone system available!

 

There's a system called MegaSquirt. A lot of guys I know run them on their Neon's and other domestic Sport Compacts. They work on any number of cylinders. I'll look into it this weekend, and try to have a report for you middle next week.

 

Dragonfire allready has a controller and a pipe out for them I think they said a 8 to 10 HP increase I wonder about that though

 

BigGun currently makes an ECU for the RZR i have them on order and will be stocking them shortly. here is a quick run down on the product:

5 Horse Power Gain

Big Gun EFI/TFI Fuel Controller

Polaris RZR800

. Increases 4-5 Horsepower over Stock

. Improves Throttle response

. Installs in minutes

. New Third Generation Technology

. No computer Needed to Adjust EFI

. Plug-in Technology (Doesn’t interfere with stock ecu map )

 

What is the web site for RZR CRAP because the link above does not work. It is a phone site.

 

It is parked, meaning they are still working on a page. Go to RhinoCrap.com

 

The mega squirt system is really a spartan system....I had one on a Conquest and it was OK. The biggest reason I had one and not an MPI system was cost. With these things having efi you might be able to hook up something like an SAFC (I had one of these on an Eclipse I had) to control the fuel curve to lean them out to make more power. I was thinking about putting a turbo on mine once the warranty runs out but then you have to worry about detonation and intercooling and all that crap. I want mine to be reliable but it's so hard for me to just get something and not mess with it.

 

 

Man I'd like to boost mine up some but I have no idea when to push buttons on these and then doing so and smoking pistons. How the heck do you use these? Also will a Rev box come out too and will a rev box and ECU work in conjunction or is this ECU a rev box? Could use some help here too. Thanks!

 

Our Engineer Craig said to give him a call 661-587-7702.

i have the dragonfire one on order w/ a uni filter i'll post it up when it comes in-

 

If you want to boost one up, you will need a wideband O2 sensor, air/fuel ratio meter, pyrometer, possibly larger injectors depending on boost, turbo and all piping, blowoff valve or bypass valve (really depends on if you want a loud chirp when you let off the gas), intercooler (air to air to save weight), boost controller, boost gauge and some way to tune the injector pulse width for optimum performance. You will need to watch your pyrometer to make sure your egt readings don't go too high as this will indicate you are about to melt a piston or rings. My thinking is that a piggyback system with a seperate fuel computer will be the most feasable in a boosted application as the alternative is reprogramming the ECU every time you change something. The other scenario is a complete ecu that you can reprogram from a laptop computer but I don't see one of those any time soon. Oh yeah, a data logger is useful too as you can record valuable information and play it back in real time so that you can make adjustments to your fuel curve at specific rpms for maximum power gains and to be sure you are not too lean. The leaner the better though as you will make maximum power right on the edge of being too lean and detonating. It's a fine line to walk. Anyway, these things are like anything else, you can do so much to them that they eat parts and are totally unreliable.....thing is though, when you feel that hard pull, it makes it all worth it! But like I said earlier, I want mine to be reliable......(I have to keep telling myself that!)

 

I also have a 800 sportsman and the rev limiter is the same at 6450 RPM so I cannot see where the different sportsman cpu will increase any speed the only way is to gear up with larger tires or some clutch work or to increase the rev. limiter.
