RZR S SHOCKS COMPUTER

I have a 2018 rzr s . does the computer that controls all 4 shocks control any other parts of the machine? Such as the motor?

Re: RZR S SHOCKS COMPUTER

No. Has gauges for engine and etc. Still needs an ECM for engine as all of the Polaris machines use. Interesting question. Curious why asking?

Re: RZR S SHOCKS COMPUTER

driving trails at 20 30 mph there is chatter like driveing over catapiller tracks. On my 2012 900 I had my shocks reworked by a shock specialist and it road like butter. Cant get this to work with the electronic shocks on my rzr s

Don't believe the shocks are causing that. Sounds more like a tire issue at that speed. All the computer does is to adjust the valve in the shock the same as the click knob on standard shocks. You just do it in the cab instead of stopping and manual adjusting the knobs. What air pressure are you running in your tires. And what tires?

Re: RZR S SHOCKS COMPUTER

tires and air are all at stock on a 2018 s . If you want a smooth ride you do that by changing the shocks for the ride that you want. Will talk with you more tommorrow because this farmer needs to go to sleep, thanks for talking.

First thing to do to get smooth ride is to let the air pressure down under 10psi. Makes a huge difference. Sleep tight. Heading there soon myself.

Re: RZR S SHOCKS COMPUTER

Does it happen on a particular side or front or rear?

Re: RZR S SHOCKS COMPUTER

happens on all 4 shocks because the computer controls all 4. Did you know that when you have the shocks on the bench you have to hook them up to a electrical supply so you can turn them off to take them apart. Remember, you can put on different rate springs and valves and other different things but the computer has (settings) that are built into the program.

Yes and the settings are readable from the dash. Still gets us no closer to understanding the chattering. With what you have stated, the shocks cannot cause chattering. They control rate of absorption and rebounding. And spring rates make a big difference. Maybe you need to call someone like Shock Therapy and have a talk with them to explain your problem and see what insights they can give you.

If you could explain in detail what you mean by “chatter” that would help us a lot.

I could ride 2mph or 50mph with my stock xpt springs and the ride would be rough and oversprung. 8 new springs and crossover rings solved that. Now it’s smooth.

By the way- I read a thread recently on the Turbo S forum where people who had upgraded their shocks/springs said it rode more rough than it did with the stock springs. This seems to be a common complaint.

Re: RZR S SHOCKS COMPUTER

Trying to get my head around what you call chattering. Come up with what we call washboards on gravel road. Bounces a car around to where one can loose control. Hit the same road in 18 Dynamix, so smooth it is unbelievable. Hit harsh whoops on sand dunes. Dynamix makes a huge difference in speed they can be taken. Cannot figure out what problem you have.

You need to keep reading to find the problem was a mid production shock change no one seemed to know about. It has been figured out and corrected.
