All that wire does is tell the CDI that it is in Low Range. That may remove your speed limiter, but you wonít get any performance change from it. The new CDI has a different curve, and the complete upgrade kit also includes different clutch components and a gearing change as well.

Since this machine doesn't have low range, that's the signal wire to apply the limiter at a specified MPH.

I'm not sure what you mean "you wont get any performance change from it" because removing the speed limiter IS EXACTLY the performance change I was looking for.

There certainly could be better programming on a normal 550 CDI that could give it a little more power. I'll reassess that once I get it to fully open the carbs, get the clutching calibrated, and we actually get some snow. This sled is for a 12 year old girl, I'm ok with leaving a little power on the table anyway.

The gearing is lower on the EVO. I'm ok with that and will leave it, and I'll probably just match the clutching to exactly what the regular 550 has.

The only other change its getting before snow is a new 1.35 cobra track and some studs. I haven't purchased the studs yet but the track has already arrived.

The machine doesnít have low range, but the CDI box doesnít know that. Thatís why the speed changes, the CDI thinks youíve put the machine in high range now (but you know better, you just unplugged a wire instead of letting a non existent switch control it). The programming is exactly what the difference is though. The sled may reach a higher speed, but itís not going to get there any quicker than before. On a 550, the CDI controls the timing curve and the programming is how aggressive the timing is applied. That will not only allow the higher speed, but allow the machine to reach the speed quicker, and it will also have more power at given RPMs to turn the taller gears and more aggressive clutching.

For a 12 year old, the speed limiter by itself is probably more than enough. But without the full size 550 CDI, there is still some being left on the table.

My gut feeling says the ignition curves are identical between the two but I have no way to verify that and you definitely cant go just by what Polaris engineering claims.

I love the sled though and I think it was priced pretty well, my daughter is coming off a gen2 340 and absolutely loves her new EVO.

Thry aren’t the same, as that’s why they’re included in the upgrade kit.

It’s a pretty sweet little sled though, we’ve had one on the floor presold but leaving soon. I checked the side panel fitment on my Pro Ride Switchback Assault, and they seem to fit well. I may order up a set of the red non ES panels and get some custom stickers done up to fit it for a totally different look.

I ordered one from my dealer back in march and got the first one that came in this fall. When they first released i saw one with what appeared to be a factory wrap. I'd buy that wrap in an instant if i knew where to find it. I've got the picture on my phone somewhere i'll have to find.

Not that it is all inclusive but the picture of the upgrade kit in the 2019 parts accessory catalog does not have a cdi in it. Does anyone have access to the actual parts list and part #"s of what is included in this upgrade kit?

I have it printed out at work, but it includes a full suspension upgrade (brings machine up to full size 550 specs), gearing, clutching, and the CDI. I can post a full list later.

That would be awesome, I'd really like to see the full list also.
