may quick research was inconclusive. i cross referenced the cdi units that the vortex is compatible with and none were the same as the atv. but that doesnt necessarily mean that it wont work, it surely deserves a call to duncan to see if it will. i am sure in the coming days/weeks/months a compatible ignition system will available for the atv's!

I know this is a old topic but I decided to dig it up from the grave.

I spoke to Duncan today and the Vortex is available for the 450/525 XC. They said it eliminates the TPS :D and the rev limiter can be programed.
Well it's $450-500 compared to the $200 for a bike CDI but you get the bennefits of 10 ignition curves and the proper rev limit.

Has anyone tried it yet?

Add over $100 to that price for anyone to program it. That just puts it way out of reach for most of us.

It comes programed from Duncan, I don't see any real reason to change it unless doing major engine mods.

if it has 10 maps, and the same limiter as stock, then i wouldnt see a reason to reprogram it imo, unless its used on a crazy build.

EDIT: At first Vortex said it did not replace the TPS, I clairified "just the button" and all is good. The button goes away. :rolleyes:

Exactly, the $100 reprogram is needed to get the rev limiter down to around 10,000. It comes set at around 11,000. That will gernade a 525.

now, when you guys say tps, are you referring to the throttle position sensor, or the throttle bypass safety bs?

cause the tps on the carb actually serves a good function and tells the cdi what position the throttle is at...

Well good news again, after explaning some stuff Vortex said YES is does eliminate the button! The TPS stays functional because it is needed for the maps in the CDI. The Rev limit is 10,650 on all 10 settings.

Duncan can set the limiter to where ever you want, it's a 5 min job. When I bought mine from Vortex they set the limiter to 11,700 for me (thats what the KTM SX motard factory box cuts at.....) this is for the SX okay !

OK guys don't shot me but I had Coles (LTZ470) for months and never got it on the dyno, so I could have told you guys what the gains are but no, I never got it on the dyno, I know, I'm a slacker

Someone called Duncan about lowering the rev limiter, and they were told it was around $100 to change it. Thats BS, but another way to make a quick dollar I guess. They can keep them for that......

Don't worry Walt, Travis will dyno it on the 637 soon...I think he is going to use a stock motor for the dyno prior to pulling the 637 maybe we can get him to test the Vortex on it also?

Help Travis!!!
