Got my idle to work wary precise.

Vw Peugeot Audi and some brands use the Bosch valve.

The only way to get the valve working correct is to connect a diode like 1N4007 or a Scotty diode.

  • injectors is coils too. And we got even better control over coil letting flyback voltage rise up to 40-50V. IAC valve usually is connected same as injector: FET + flyback circuit. From my experience with flyback connected IAC needs high DC around 80-90%. Below ~50% it opens in other direction - mechanical fail-safe mode - ~1200Rpm. It is using same frequency setting 0.

  • The Dc when could is 50% 1300 rpm and 40% hot 800 rpm.
I also use injector output see my wiring but my inspirings shows that the diode is needed badly fore this kind of valve.
