Don't really understand it either but was looking in the manual yesterday to see what the air pressure should be and it listed it anywhere from 20-90 lbs depending on load (your weight plus passenger). Checked mine and it was just below 20 so I put more in to bring it up to 30 since I ride without passenger and weight 180. Haven't had a chance to try it yet but it had seemed a little soft before with setting in the middle.
As Dave said, it does both. The Spyder gauges off and maintains ride height, but a higher ride height requires a firmer suspension (more air pressure). The firmnes is variable, however when the ride-height is the criterion. The same setting with a passenger or cargo, by necessity, is firmer to maintain that ride height, but will be a little softer with just the rider aboard.
Manually putting air into the RTS or LTD (or releasing some) does nothing. As soon as you start to ride, the pressure will be adjusted to maintain the ride-height ("firmess") setting. If you want it firmer, raise the setting.
I think that what you are saying is that the firmness setting adjusts that ride height, not the firmness. If so, that is not my understanding of what it is intended to do but, it could easily be correct. My wife claims that she can tell the difference in the setting. I cannot.
That is correct. Firmness is relative, but is closest to air pressure. The pressure must be increased to increase the ride height, however, so they are closely related.
I'm having a problem with the word manual coming on my screen and I have checked the swing arm and everything is ok. I've tried to let it run, parking break off and in gear, push the up button and still get the manual on the screen. Now someone says driving it, so what's up?:dontknow:
Your ride height sensor link could have come disconnected or broken, your air release solenoid could have failed and allowed the suspension to top out (exceed limits), or you could have an instrument cluster that has the ACS high and low limits programmed to the same value from the factory. Look at the ride height sensor on the left side where the link connects it to the sensor and swingarm. If one end is loose or the link is broken, it needs repair. If the suspension will adjust manually when you hit the button a second time after "manual" appears, measure the height of the rear fender above the garage floor at different settings. If it doesn't adjust and you cannot hear the air release solenoid valve hissing (with the Spyder running, in gear, and the parking brake released, have your deale test the solenoid. A misprogrammed cluster needs to have the dealer reset the limits using a gauge block and BUDS. I think there is a service bulletin, but if not have the tech contact BRP dealer tech support. They are very aware of the issue and the fix for it.
