    How much torque is available at the valve shaft?

    Why wouldnt TS design these things for fail open, I can't think of a reason why it wouldn't be the best outcome in the event of a failure and for a clean sheet design I don't know why it wasn't considered.

    Apologies if this stuff has been covered already or I'm way off, I'm just intrigued why no one has ever done it before and I'm not much of a youtube watcher.

    edit: 21mm per second travel, 600ms to full travel.
    No fail open would be possibly a result of keeping current draw reasonable for the required torque/force, especially under hold conditions (when it could be zero) Fail closed is much more important in a DBW throttle for example and luckily much easier as the torque/force requirement of a butterfly valve is much lower than a poppet valve, i remember fingerbanging an unpowered DBW throttle some time ago and it moved quite freely.

    0.6 seconds closed to open seems like a long time compared to a pneumatic valve, i'm sure it is still fast enough though.

    This bit of the FAQ is a bit confusing

    What do I need to control it?

    You will need a programmable ECU (Engine Control Unit). You will need a ‘high current’ (20amp) output and a spare analogue input to make it work. Most quality ECU’s have the capability to drive the gate for accurate boost control. Best speak to your specialist, or calibrator about your needs if you have any questions on what is needed.
    not sure how you would drive the motor in both directions with only one ECU output.

      They're either being coy on purpose or their marketing department doesn't talk to the engineers very often. (what a surprise)

      Oo___oO

        Bit more information in this video. https://www.youtube.com/watch?v=PDkDFFRBc-8

          Does anyone know if there has there been any more information on handling the electronics on these yet?

          A mate and I are going to try and build a set up for a 7670 EFR, on my 2008 BMW E92, using the turbosmart eWG45 (TS-0553-1502)as the WG actuator and a shaft from the turbosmart gen V IWG EFR kit (TS-0620-4012)
          Because the 7670 uses a IWG, we need to merge the two kits together to work like the set up in the picture below
          The turbosmart kits are on the way and we will have a better idea of if we can make it work when they arrive next week

          The next challenge will be of course how to wire it up and get the stock DME to talk to the eWG45
          In the promo vids, it seems turbosmart are developing a solution, but it is probably a while before this becomes available, so the only option atm is to DIY

          From what I understand, there are a few challenges to overcome, including 20 amp supply and some form of custom board to convert signals etc
          Does anyone know if there is any technical info (from turbosmart or others) who are working on a project or have done an install ?

          Any suggestions on how we might approach this?

          Thanks everyone

            Something like this you mean?

                if you're using an internal wastegate, there are plenty of OEM solutions for this already out there.

                the turbosmart is the first external gate to do it.

                  They struggle to hold much backpressure, and the EFR gate head is pretty large for IWG

                      Kinda similar to a relay. Its more like two relays which you use together, and turn on & off MUCH faster.
                      Look up how a H Bridge works.
