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.
- Q: what was issues without diode? How reference table looks then? MembersPage/GintsK
- It’s a must to connect the diode you will newer be able to control the coil/Iac without this mounted be curse the voltaic is flaying around and the coil will newer be discharged and the results is the car is running at high rpm.
- 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.
- Q: How much idle changes versus DC% changing?
- The Dc when could is 50% 1300 rpm and 40% hot 800 rpm.
- I try it. Significant better!!! Main advantage is widened PWM range - more resolution.
- I tested this as well. IN4007 diode increases resolution range from ~20% to ~55%. Is there another value diode we can try to improve this even more?
- You could try the SS24 http://www.onsemi.com/pub_link/Collateral/SS24-D.PDF
Here is a good starting set up fore the idle
