I've removed the flyback diodes and the valve moves more.

However it does not move in a linear fashion and makes a high pitched squeal. Sounds like the PWM signal.
Also I can only close and open the valve to 50%. Can't fully open the valve regardless of manual slider %.

Any particular settings I can use to make the valve move properly?

Hi.
Sorry I had no chance to check my settings in TS. Spend whole weekend trying to create ini file for my own board. No luck. Also stuck with some strange bug with slow ADC.
But I was able to validate that two-coil code is still working in master. Tested using console.

You can check my settings https://github.com/dron0gus/rusefi/blob/board-subaru-eg33-dev/firmware/config/boards/subaru_eg33/board_configuration.cpp#L148 and https://github.com/dron0gus/rusefi/blob/board-subaru-eg33-dev/firmware/config/boards/subaru_eg33/board_configuration.cpp#L68

Idle makes some noise at 250 Hz. This is ok.

When you say "tested using console" was there a an actual Subaru IAC hooked up?

Yes. It was connected. FW was running self-simulation and blipidle command was used for idle valve testing.

Ok. I'll see if I can post a video showing valve position at 0-25-50-75-100%
Def not acting as I expected it too.
