    Hi all,

    Had a search and happy to be steered into one which provides the answer.
    Have an LS3 Calais wagon with plenty of fruit (Magnuson 2300 etc).
    I’ve taken out the VCM Cam, 1 7/8 headers with a complete 3 “ and put in LSA spec Cam and full exhaust. The exhaust has BI modal and hate the minimal noise where the valves close under low rpm range with bi modal on. I have removed the relay to have the valve gates open permanently etc. I want to have an individual switch (not through my link) to open or close the valves so in 4am starts it can be easily done (not plugging in a relay each time).
    Anyone been able to do this without doing a Varex etc as yet?
    Thanks

    I have Varex on my Jeep SRT.

    have full system on it. Get them with smart box that plugs into your OBD, can program the valves to be open / closed and micro adjustment based on rpm, throttle position, and speed. Can also set up geo fences so valves close in certain locations as it has in built GPS.

    Just want to tap into the current valves hopefully.

    So did this provide a work around to either have open or closed (not be open and close pending rpms etc)

    There's also the same product from LSXtreme for $185. I'm looking at getting one of these fitted to a Director so that I can have the option of open bimodals in the comfort MRC tour mode. Will be happy to hear anyone's thoughts if they have purchased this or a similar product?
    The Varex is nice but far too expensive as an option unfortunately.

    Seen the ebay one in action. It looks home built with most of the parts available from jaycar. Works a treat though. Nothing wrong with it.

    I have that exact ebay one. Seller and product is extremely easy. I got the big singular button for simple looks. Dual button might make it easier to know on and off though.

    This would be esy to hard wire to a switch in the cabin. It is just moving the relay to control it instead of the vehicle.

    Yeah wiring is easy (I’m an electrician). Just want to make sure it isn’t a step motor or require voltage pulses as opposed to a direct drive open/shut motor etc.

    it is a 10v @ 200hz pwm system which uses a duty cycle of 80% and 20% to control the valve motors

    this may provide some extra info for you

    I have this kit fitted to my VF2 Redline. I have bimodal off in the my link, so the 2 button remote controls open/close, works great. When going for long drives, to like Mildura, I change the my link to on, so the remote controls auto/open as it helps to minimise droan when sitting on 115+ in auto mode for the kids in the back with their gadgets.
