    Please can you tell me if you do the same plug up the hose on in the engine bay on a Cali T to keep the valves open?

    Anyone know if there is a fuse you can pull to keep the valves open, some people say they have done this with an F12 of the same era?

    I too am curious to hear everyone's thoughts on the Cali T as well. Let me know if you figure this before I start unhooking lines :)

    I've read a few things that suggest that most Cali Ts (later models), the vacuum actually opens the valves, so disconnecting would leave them constantly closed. Can anyone confirm?

    I'm not 100% when the change was but the early model California T was setup like most

    That is correct. You can always have someone make you a dummy plug to help prevent that check engine light since, all it is looking for is for a closed circuit.

    I have just ordered the materials to make my own remote control system for my california.
    Plug and play totally reversible.
    Parts total cost £12.00 including remote control key fob and remote diaphragm electronic valve

    I will post when fitted.
    Cheers Andrew

    Right I assembled all the parts that I purchased today, works like a charm for the princely sum of less than $10 including cable fitted.
    $299,00 bucks for the kit ready assembled online seems excellent value .

    Please see pictures

    This method works !!!
    So much easier than working at the rear exhaust valves.
    Now I just need to order the remote on/off control module and solenoid valve and will be perfect.
    Thanks a lot !!!

    Awesome... thanks for that. Just saved me $2000 instead of having the x pipe muffler delete fitted.

    Following up and answering my own question in case it was unclear. Took the car up to my local dealer and chatted with the team. Confirmed that the vacuum does close the valve. I had them unhook the hose and plug the line, exhaust is always open and I think its perfect. My car's production date was February 2017.

    Hello, did you ever locate the exhaust vacuum line in the engine compartment of the California T?

    I tried this solenoid valve.
    When it is closed, it is not able to vent the vacuum downstream, hence the exhaust will remain closed.
    So it doesn't work.

    Hi Andrew, Gordon here in Scotland. Happy New Year to you btw. I see in the ad you posted above, it is for a 220v receiver. I presume you ordered a 12v one? Also, did you use a switched live for your setup or tap off the battery directly? Ideally I’d like a switched live near to the vacuum hose under the bonnet, if this is what you did also, where did you connect it to?

    Cheers and thanks

    Def.

    Hi Gordon
    The unit is indeed 12v but the seller has a drop down box to choose which type you wish to purchase, the picture is of the advertisement on eBay.
    I connected the unit direct to the battery with the inline fuse, I could not find a switched live other than for the fuel injection and I did not want to butcher or splice into the FI circuit.
    The current draw on standby is lower than the radio uses for keeping the clock and memory there is also a significantly larger current draw from the alarm key fob receiver.
    I figured that the car is never left for more than a few days without being on a tender anyway and I also worked out that the current drain is so low that it would take weeks to discharge the battery so it’s not even worth taking into consideration taking into account how I use my vehicle.

    cheers
    Andrew

    Not sure why this guy was "banned" but this is exactly the kind of cheap and easy hack people love these types of forums for. This worked great for me. Now my Cali displays the right kind of "attitude" at low rpms. :cool:

    Not the most exciting, but probably the "easiest" - I just took mine to my local dealer and asked them to plug the vacuum hose that hooks ups to the solenoid controlling the valve, I think it cost me like $300-400 total for labor. 100% love it and will never look back. They can always re-attach later if you necessary.

    Just spinning this thread back up for a quick question. I know on the original Cali, you could just plug the hose from the hood, has anyone figured out if that is the same on the T?

    I see the way to do it from the back of the car, but the front hood method was so much easier.
