Denis Tan Posted February 11, 2010 Report Share Posted February 11, 2010 Hi, I cannot seems to get this three wire Bosch idle solenoid operate correctly. I have set the frequency to 200hz, min clamp 20% & max clamp 80%. Wire in as per instuction manual to Aux 1 & 2. Idle speed fluctuate quite a bit with the same duty cycle in PC Link running status after drive. Quote Link to comment Share on other sites More sharing options...
Nigel Swan Posted February 13, 2010 Report Share Posted February 13, 2010 From memory I used 50 to 100Hz on a Bosch Idle valve. Worked anywhere in that ranged but affected what duty was required for a certain opening. Quote Link to comment Share on other sites More sharing options...
Nigel Swan Posted February 15, 2010 Report Share Posted February 15, 2010 The one I did was a 2-wire, I would expect similar frequency settings to work on other Bosch valves. Was using a different ECU though not a Link, and was just a matter of adjusting PID settings to get it to idle like factory, including aircon idle-up etc. Was plumbed into a Audi A4 B5 1.8T intake.
