savagecanuck · #1 (**permalink**) 02-19-2009, 11:33 PM

I have a 09 Rhino and have done the sheave mod but looking to get rid of the rev limiter. I plan on no other mods except for a unifilter.What are the pros and cons to this CDI box as its a good $100 cheaper than the MSD set up
Thks for your input

Go with MSD, is way better aud easy to tune,with dynatek you have to buy a remote module to program it.do a search on MSD threats

If all your wanting to do is move up the max rev the Dynatek would be a good part, BUT they are haveing alot of trouble with it right now. With that said i have the dynatek and several of my friends have them with no problems.

Don't even waste your time or money on a Dynatek ! Look at the msd or vdi ecu. I have the msd ecu. Any of the vendors carry them - Utv crap, Hunterworks, or Unleased. Call them they will set you up right for your application.

I would avoid the dyna boxes. Man I had horrible issues with mine and finally just chucked it in the trash. I didn't want to sell it to anyone and have them come attack me when it started doing what it does.. Which is randomly cut out completely.

Mine had been sent back to dyna 2x and both times they said they repaired it and it was perfect. It never was. Would run good for about 30 minutes, then it would start.. Going downhill for long period of time (like forest roads) I would push the pedal and get nothing, had to hit it like 10 times to get the motor to kick back in.. Going up hill it would randomly die out, and I would have to pedal to get it to come back to life.

TPS Tested perfect. All connections were checked, and it just wasn't ever right. MSD is perfect.

I have the Dynatek and it also stalls the engine every once in a while, but not bad enough to get rid of it. Get the MSD for sure, I didn't have a choice a year or so ago when the first ones came out.

Dynatek Sucks. They have had problems and continue to go un-resolved, They have had the same problems for a year now and will tell you that it has been fixed. Don't waste your time or money. $100.00 price difference now will even itself out after you fed ex you Dynatek back to them 5 times for them to try to "re-flash it"

Dynatek has proven itself to be garbage, do some reading on it, you will quickly find out what everyone is talking about. Save yourself a huge headache and go with the MSD, or hurry up and wait for Unleashed to figure out the VDI. They have been working on that since December?

Thats true that most of the dynatek are junk but there is some good one's around too. All i was saying is that i have the dynatek and its working fine, but who want to take the chance on one now days. But the MSD will do everything you want plus more so dont let me talk you into buying something that might or might not work.

My dynatek results

Well I just thought I would share my info with all you guys. I have a 2008 700 with:
1- Dynatek ecu/cdi
2- Dynatek fuel controller
3- Afe intake
4- Modified Sheave
5- Duner kit with the internal springs installed
6- Power exhaust tip
7- Grinded welds on the stock exhaust

I have to say I have had no problems with my Dynatek stuff. After some different tests at 2000-3000' with my mods listed above the best settings on the fuel controller are:
Base 1
Low -2.5 (negative 2.5)
Mid 0
High +5
Curve 2
With this setup I am getting 12.5 to 13.2 or so Air/Fuel mixture and the plug is perfect.

I am able to get 60mph on flat ground.

The problem is in the Rhino and not the Dynatek but not all Rhino's have the issue therefore the Dynatek messes up. Not sure why the MSD works flawless but it does.

If the Dynatek as you said, "messes up," how is that a problem with the Rhino. IMO, The fact that the MSD works flawlessley is only further proof there is a problem with the Dynatek.

Our Rhino runs great with the Dynatek. Best mod ever, eliminates the speed limter.

**Hunterworks** · #15 (**permalink**) 02-20-2009, 07:26 PM

What I mean is there is some kind of differences in between Rhino's and the dynatek picks it up and the MSD does not.

Kind of like our TriFire CDI had issues with the neutral gear position switch when it was not working correctly but the Dynatek and stock CDI didn't care. It was the switch but our CDI didn't like it.
