i have the dynatek ignition on my stock rzr s and im happy with it. feels like acceleration improved and gained 5 mph on top.

 

Is the ignition the only mod ypou have???:

 

If I am not mistaking I think that all the ECU's are re-programmed by MPI!!!!! I know for a fact that Hot ride 4 you is MPI. I have been to MPI and they are one cool operation. They do everything from UTV's to drag or race cars. Anything with a engine they have something for. They make a lot of their own stuff!!!!! So far I have been happy with my new ECU... haven't raced my friends yet though.

 

bump, any more feedback? im interested as well

 

I have an MPI ECU in mine. Its at the dyno shop now so I will know numbers when it comes back later this week. I did notice improvements on throttle response and of coarse the higher rev limiter came in handy with the lighter clutch weight.

 

Get the ITI unit. Sooo nice.

 

I am contemplating the Dynatek too, I would like to hear more input on what is a better box, any problems with a dynatek first then adding an exaust pipe?

Are talking about the CDI ignition box, or the FO controller?

 

I orderd a dyna tech cdi box friday ill let you know what think when it comes in i also have the dyna tech efi controller exaust and k&n air filter

 

Yea, I mean so far its looking like the dynatek doesnt make as much performance gain as the MPI or Hotride4u box's do. But id like to get more imput

 

from everything posted it seems they all make a big diffrance on stock rzr's and a smaller gain on moded ones

 

I'm really satisfied with my Dynatek ignition. It has improved the low and mid acceleration. Still havent been able to test top speed. I dont have too many areas around my house I can get up too speed with out getting flashing lights in my rear view mirror. :ride:

The dynatek is supposed to be the best out as of now. I run mine with the Trinity racing fuel controller.
