    Goal: Drive the HP Fuel Valves through CLOSED/START/RUN via hardware inputs (ideally my Honeycomb Bravo axes + reverse detent buttons)

    Issue:
    When I spawn in Cold/Dark my HP Fuel Valves are always in the OPEN state.
    I manually move them with mouse scroll wheel to CLOSED, and then I use my mouse wheel to articulate them to START and OPEN during engine startup. But I would like to drive these with my Honeycomb Bravo hardware.

    I have tried every Fuel Valve (nominal, 1, 2) binding available "On" and "Off" and "SET" to get them to articulate but none of those mappings move the valve models in the cockpit and I can't tell if they're doing anything behind the scenes in the sim.

    I have ensured that none of my HOTAS equipment is mapped to any fuel or engine systems except for Throttle 1 Axis and Throttle 2 Axis, so I shouldn't have any other controls overriding my attempt to drive the F28 HP Fuel Valves through the Fuel Valve 1/2 commands (recommended bindings in the manual).

    Has anyone had success driving the HP Fuel Valves with hardware bindings?

      The following control assignments can be used to move the HP Fuel Valves between OPEN and SHUT:

      SET ENGINE 1 FUEL VALVE
      SET ENGINE 2 FUEL VALVE

      If you're using a third-party software such as FSUIPC or spad.neXt, the following Lvars are used to control the HP Fuel Valves:

      F28_PED_L_FUEL_LEVER
      F28_PED_R_FUEL_LEVER

      A value of 0 will set them in the OPEN positions. 1 in the START position. 2 for the SHUT position.

      Hope that helps.

        @Mark Thank you!

        I'm going to try and map them to raw buttons first, then I'll see if I can go through FSUIPC or something to get them onto my axis.

        If I get this working well, I will see if I can make a blog post or video for other users 🙂

          @joncoughlin Just curious, did you ever figure this out? I'm currently working on the same issue, using Axis and Ohs. I tried to use chatgpt to write an RPN script for the purpose, but probably because I'm not experienced with LLM prompts, I gave up after about a dozen non-working scripts.

          EDIT: Just to clarify, I'm able to control them with button presses, but I dropped some money on the ProDeskSim F28 levers, which includes the fuel valve levers, so I'd prefer to find a way to bind them to axes. So I can set the LVar to 2/off with the button at the bottom of the axis, and I can set it to 1 when that button is released, but I have no elegant way to then set it to 0. Too bad the Bravo doesn't have detents you can set as buttons, like the Thurstmaster Airbus quadrant.
