DynaTek Features
Dynatek Non-Programmable Ignition Features
- Improved Timing Curves
- Higher Rev Limit
- Removed Reverse Rev Limit
- Overrides belt indicator for full performance at all times
- Increased Spark Energy
- Improved Throttle Response
- Easier Starting
- Plug-In Module Replacement (Easy Mounting)
Calibration: The Dyna FS ignition is preprogrammed with a performance curve, based off of the stock curve. The final timing has been increased 5°.
Rev Limiter:
The Dynatek also bumps the limiter up to 9,200 rpm over the stock 8,500 rpm. This is only going to affect a small number of riders. I'm sure there are going to be a ton of people that disagree with me on that one, but let me explain. First, understand what it means to hit the rev limiter. When you are in reverse and hit the limiter, you know it because the machine sputters. This is the exact result of hitting the rev limiter in forward - the engine will sputter. If you want to see what it's like, put the bike in neutral and hammer the gas. Many riders hit a flat spot around 63 mph and assume they have hit the rev limiter, which is not the case. To appreciate my position on the limiter, run a good tach. With stock tire size I would push higher but I'm running 26" Mudlites \ 26" Ducks Unlimited Wetlands. In talking with Dale at Dalton, the Prairie is 'out of gearing' by the time it hits the 60+ mph range. Clutch work will get you up in to the higher rpm range faster, but not give you a huge increase in mph.
APPLICATIONS
The Dynatek CDI delivers two key improvements over stock - advanced curve and no retard above 6,500 rpm. Not only does it pull harder, it does so all the way to the rev limiter.

Installation
Installation couldn't be simpler.
1: Remove the seat
2: Unhook the positive side of the battery.
3: Remove the rubber holder that has the stock ignition attached.
4: Be careful when you separate the stock ignition from the harness, so you don't wreck the connectors.
5: Slide the Dynatek CDI into the protective rubber boot.
6: Plug the Dynatek CDI into the correct connectors ( no brainer, even Tim Allen from Tool Time could do this installation).
7: Place the rubber boot with the assembled Dynatek CDI back on the tabs. Make sure it is pushed all the way down the taps, so it will not jiggle free.
8: Install the battery connections.
9: Replace the seat, and remember to catch both seat tabs, so your seat will not fly off with you on it.
10: Start up your quad and get ready to enjoy your new Dynatek experience, of smoother power throughout the rpm range.
DYNA Features that we like here at ATVProductTests
My quad comes with the timing retard. It really makes for lousy starting and sloppy take off's.
The Dynatek CDI
takes care of these issues, allowing you to have better starting with
great acceleration, when it's time to launch your missile. (CAUTION! 9,200 RPM LIMIT )(8,500 stock)
The Reverse override button, belt
trip, limp mode are all stock "features". This sucks when you are stuck
and trying to gun it in reverse. Or your limp mode goes on when you are
back in a swamp and you only have 2 wheel drive to get you home at a
snail pace.
The Dynatek CDI gets rid of these items:
# 1 >The reverse limiter no longer exists: This means that the override button is no longer needed. The important thing here is to just be aware of it, and use care when backing up. I found the reverse limiter to be more of an aggravation than anything else and I am glad to see it gone.
# 2 >The belt switch is no longer active: This one is very important! It means that you need to take the maintenance of the belt seriously! If you run the Dynatek, there is no running the belt like it's never going to wear, break, or get loose. If something goes wrong, you could find yourself on the other side of the handle bars quick, fast, and in a hurry. If you have been checking your belt and changing shims, or replacing the belt as needed, you have nothing to worry about - short of a catastrophic belt failure.

Tuning:
Use of this ignition may require rejetting of the carburetor to supply more fuel to maximize performance gains. If you are unsure of this tuning process, the services of a competent mechanic should be employed. Do not operate the engine in a lean condition for extended periods or damage may result.
This ignition will allow the engine to rev to a higher RPM than what it has before. Stock rev limit is 8,500rpm. The DFS rev limit is pre-programmed to 9,200. Because the rev limit is increased, the performance limits of other engine parts (valvetrain for example) may be found. It may be necessary to replace these parts for best engine performance. Consult with an engine builder for answers on what works best for your engine.
Troubleshooting the Dynatek ignition is simple. If the bike will not start or run at all, reinstall the stock ignition. If this fixes the problem, then the Dynatek ignition should be returned to Dynatek for testing. If this does not fix the problem, then the problem is somewhere else on the bike. Follow the troubleshooting procedures outlined in your bike shop manual.
If you are using non stock plug wires, ignition coils, spark plugs, etc, replace them with OEM units. If this doesn't fix the problem, reinstall the stock ignition. If the problem persists when using the stock ignition, then the problem is external to the Dynatek ignition.
FAQ - Frequently Asked Questions on the Dynatek CDI:
Q. How much HP/MPH/etc. will it deliver?
A. It is going to depend on your bike.
Q. Will I be able to keep the front end on the ground?
A. Of course. Who are you kidding !
Q. Will it work with a module - i.e. Holeshot, HL, etc?
A. No. The module and Dynatek CDI can coexist without a problem, but you'll get no benefit from the module. The Dynatek CDI doesn't use the speed sensor for timing which is what the modules fool with.
Q. I don't have any mods, will I benefit from the Dynatek CDI?
A. Yes. Stock bikes will benefit from the improved timing curve but less so from the higher rev limiter. A stock bike is going to be limited by clutching and other factors before the rev limiter comes into play.
Q. Does the Dynatek CDI push the bike harder than it can handle?
A. Not at all. It may push it harder that you can handle, but no more than the Prairie can.
Q. Will I need to rejet?
A. Maybe. You'll have to run your bike and see where it is from a jetting perspective. There are too many variables to say for sure that you will or won't have to rejet.
Q. Does the Dynatek CDI require premium fuel?
A. No. Stick to the fuel recommendation in your owners manual or higher.
Q. Will my Speedo, KEBC, and other speed sensor driven 'things' still work?
A. Yes. The Dynatek CDI doesn't disable the speed sensor, it just doesn't use it for the timing curve.
Q. Does the Dynatek CDI affect how the 4WD engages?
A. No.
Q. What doesn't work with the Dynatek CDI?
A. The reverse limiter and the belt sensor are no longer active.

DynaTek CDI Field Tests. All product's used in these tests were supplied courtesy of Dynatek
I have been running the Dynatek CDI's on both of my machines since I purchased my machines almost 2 years ago. I have had trial and error problems with my quads along the way, and had tried to shift the burden of error to the Dynatek ( My point is when you start modifying your quad, change one variable at a time!). With a lot of help from Scott at Dyna, and an abundance of support from my Nyroc Forum friends, I have learned that a simple problem is not always what it appears to be.
