yes, i understand what he was saying, basically it controls the amount of air that is let in and out. We tried it last year and it ended up being aborted because it was soo complex. It is possible, however those circuits tend to be cranky and i wouldn't advise doing it.

Re: Is it possible...

sorry, its a jeep thing. Being a jeeper, we tend to call the lowered faster cars, ricers, due to them bing imports. Its a diragatory(sp) slang term, but it seems to have become part of the world.

I know more about suspension lifts and controll arms than i do high output engines and airbags

Re: Is it possible...

You could have 2 speeds by running the vents to a solenoid valve, and use it to switch between two flow controls.

Red face Re: Is it possible...

Yeah, someone was telling me that just today. We posted a question about it on the FIRST Q&A site, but it wasn't specific enough... my buddies want to know if anyone knows how to wire a solenoid valve? It figures it'd be complex... tooo much for brain!!!!! AHHHH!!! NEWay, thanks for the advice, it helps a lot. Do you know anybody going to the Arizona Regional? That's where my team will be heading... Never been off the east coast and it'd be nice to meet some "Westerners", pardon the expression... no offense.
Thanks again!

Re: Is it possible...

know im coming into this discussion late, but there ARE things you can do programming wize to change the speed at which it comes out and also how far it comes out.

1. changing how fast it comes out:
-tell the programmer to set the code so that when the soleniod is fired, make it relay on and off--the simplest solution to changing speed by controlling the amount of time that the solenoid allows air flow.

2. changing how far it comes out:
-hook up a second solenoid to the exhaust of the first one. in order for this to work, use something like a joystick interface, where you have control over positive, neutral, and negative current on the fly. dont have the exact code off the top of my head, but we did it this year and worked like a charm.

to control them remotely? hm. if you could change the frequency of open/close valve on the first solenoid by a dial and then the firing by a joystick, it could all be incorporated on a remote control of some sort.

just stopping in and giving my 2 cents, even though theyre late.
