I am facing difficulties in finding the correct PID settings for the BMW M30 Idle valve. BMW Part # 13411286065 Bosch Part # 0280 140509 It can not handle the idle when I activate AC. It does not matter if I activate PID settings on or off. I tried a lot of different values to find out good working settings but not worked. If anybody used a similar 3-wire PWM idle valve and found good working settings for all conditions, and is willing to help I would appreciate it.

Hi, I think your Frequency is to high. ![grafik](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/4/44874412ce16713c73194ee31381cc9668996f32.png) ---

Hi team, In V3 the “3wire No Spring” does not exist any more … Why ? ---

Anyone using the 3 wire bmw idle valve succesfully with V3 software ? Application BMW S50b30 turbo. Finding it very hard to get it working or even responding. Wired up on aux5 and aux6 with 12v switched on center pin. Is there a need for a resistor or anything? On V2 you can also hear the valve buzzing and changing tone if you change the frequency but nothing in V3. I can get a response if i override it ![3_wire_isc_idle_valve.thumb.jpg.1fc57788b0041c46feff4bf0d9b02404](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/c/c364a30019980e347d0233e457a175e51b29851e.jpeg) ![images (5)](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/1/16a78e9c4f233cfc37226e780a9a70bbc4bfb9e7.png) . The used valve was replaced with a new unit and no difference. Also adjusted the throttle stop thinking it was binding and no difference. There is not much info online or suggestions on the application using a Emu Black. Is it worthwhile changing to the wiring variation using the single aux and resistor for other wire to ground ? Pics attached. My understanding is its less resolution but its better than not working at all. Was contemplating changing to a 2 wire but the valve has a different angle that wont work out. A bit frustrated battling with this for 2-3 weeks.
