A bit off topic but IIRC (could also be I dreamed it) there was posted somewhere a link to a device that could be plugged in place of H bridge actuated actuator and gave out a PWM signa to control a solenoid.
I am in the need of such device. I need to control 2 solenoids on my car and I adjust the tuning to make the desired duty cycle on the ASV and Swirl output. (DC motor with H bridge control inside the ECU) so I cannot leave away the actuator physically. so my solution now if to tie wrap an actuator under the hood, plug it in a tap into the position sensor feedback and use this voltage to modulate a PWM signal. it works but is quite ugly solution for something simple I feel
