Is IACV PWM controlled? Or just a stepper?

[Jorge_EETC]

I'm fitting a speeduino ECU on the k11 facelift 1.3 dizzy, and I need to know if the IACV valve is PWM controlled or if it's a stepper motor

The heynes manual shows 2 coils (or at least they look like coils), so they would be a stepper, but they have different naming...
One is IACV FICD SOLENOID VALVE and the other one is IACV AAC VALVE...

Any idea?

Cheers
