For you guys that have it,What does it look like and where does it go?

 

It looks like the stock CDI under your seat, just unplug your stock CDI and replace it with this one. Takes under one minute.. fixes limp mode, improves low end power, runs cooler (no more getting your leg branded by the heat shield bolt), cleans and disinfects too!!

Sorry 'bout that last part, just pulling your leg... so far the only sure fix for limp mode is the Dynatek CDI or buy a 2005 650. As others have already said, the factory limp mode cure is a "band-aid".

Got my ATV Customer Satisfaction Survey in the mail today..

How long have you been using the Dynatek CDI?
Have read on other forums of some problems with this aftermarket CDI, such as burn-out units.
How is your stock battery doing with the Dynatek?
Does the Dynatek require Super unleaded. I now run 88 octane b/c here in the SW & Rockymountain States, 87 octane isn't available. does the Dynatek need the 91?
Not only this Dynatek fixes the limp-mode but does it also make the reverse override mute? And if the reverse override is no-more, how does the Cat 650 handle backing up, faster over stock, slower or the same?
What is your avg gas mileage now with the Dynatek vs the stock unit?
Not all of us would buy such a device (Dynatek) for all out performance gains but other gains like a "cooler running motor, no more limp-home-modes & better MPG", may make the $250 worth it. Others & even myself may believe it is worth the wait for Arctic Cat to finally to get it in gear & FIX this Limp-Mode problem for good on all of the '04 650s, not just the bandaid fix of the reset-plug.
I like the way the Dynatek is set up vs the DG3, since the Dynatek is a replacement & improved CDI Unit & you just plug it in with no wire cutting or tapping into the other wires like the DG3.
I bought the DG Holeshot for my Prairie 650 but wasn't all that impressed with it. I even put it in the Cat but again I really don't see what the big talk was all about.
Thanks

 

Another question: What effect does or might it have on long term durability of the engine or on reliability? (reliability meaning: fouled plugs, carbon buildup, etc.)

I had two buddies, one with a Chevy S-10 and one with an Astro van, both with the 4.3 V6. The one with the S-10 bought a power chip and increased his power. His engine started burning oil and he had it rebuilt at about 80,000 miles. The one with the Astro kept it bone-stock and sold the van for a few hundred bucks with 235,000 miles on the original engine, and it still ran well.
I know that maintenance could have played the ultimate role in this, but it gives me pause on reprogramming factory engine settings, especially considering that the 4.3 in that S-10 is the only one I've seen that didn't go at least 150,000 miles.

I like the claimed benefits of the CDI, but I don't want to take one step forward and wind up two steps back. Fortunately, I havn't experienced the limp home issue yet, so I'm on the cautious side. (My 650 was early production. I picked it up in October of '03, so I know it does not have any fix of any kind.)

Any info would be appreciated.

 

Hey guys, well i have only had the cdi installed on mine for a couple hundred miles, but i haven't had any problems with it at all. I have the availability of 92 octane fuel close to here drive by the gas station every day to and from work so that is what i use. When a peron uses a smaller engine in atv's, snowmobile, lawnmowers and so-on it always helps them run better using a high octane fuel. I am here to tell you it does not require higher octane fuel though but if i have any problems i will post them asap.

 

I just put the Dynatek CDI in this past tuesday (ordered it end of may, took 6 weeks to get it).. I won't get a chance to do some serious riding until next weekend when I head up to Tower City. I've been riding in my yard with my kids and on the road in my neighborhood. Seems to run cooler as I'm not branding my leg on the heat shield bolt like usual, and it starts up easier on regular gas. I will keep the stock CDI with me when I go riding in case the Dynatek has problems. Don't know about gas mileage or other concerns yet, but I will let you know after I put some miles on it. Riding in low range all last weekend averaged about 10 mpg with the stock CDI. A friend of mine just got the factory fix for his 650. It is a surge suppressor that plugs in the 2 pin connector by the belt housing and grounds to the frame. He's coming to my place tonite for a bbq, I'll find out more then. He's going riding with me next weekend so we'll get to compare the two side by side.

 

Was your buddy having a lot of trouble with limp mode or does he have connections?My guess would be both,my bilke has been down for the past couple of weeks so I get a break from the limp mode fairy.I love my bike and miss riding it but I don't like looking at that darn belt light all day waiting for it to start flashing.

 

He was at his dealer's, getting the EPI spring installed. They were talking about limpmode & the Dynatek. He said he didn't want to spend that kind of $$ to fix it and it should be AC's responsibility to fix it. Dealer made a phone call to AC, they sent him the surge protector. That's all it took.
