nissan200sx.dk Posted October 5, 2013 Report Share Posted October 5, 2013 Hi. My idle control valve works backwards.... When duty cycle rises, rpms drops. Its a 2 pin wired to Ign 8, with diode mounted, as the manual says. Type selected in the software is a unipolar, 6 terminal. Any ideas?

lekonna Posted October 6, 2013 Report Share Posted October 6, 2013 switch the wires on the connector? Quote Link to comment Share on other sites More sharing options...

Simon Posted October 7, 2013 Report Share Posted October 7, 2013 On the setting for the ignition drive do you have is set to ISC or ISC slave? The other factor could be some solenoids have a minimum duty cycle that if you go below it starts to open up again. Swapping the polarity should make no difference. Also check the frequency this should be up around 250hz Quote Link to comment Share on other sites More sharing options...
lekonna Posted October 7, 2013 Report Share Posted October 7, 2013 dude, you are correct. i have the 3 wire on on mine, thats why swapping helped me. Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 7, 2013 Author Report Share Posted October 7, 2013 Simon: I can only select "ISC solenoid" for my ignition drive output. (Use number eight, if that makes any difference) My setting is 200Hz, as recommended in the manual. but will change it to 250Hz. I have to limit max clamp to 20% then it idles nice. If I up max clamo, revs just goes down. It kills the engine if set to more than 50%. When the ECU want to increase revs, by increasing duty cycle, revs goes down. So it cant figure out to control idle at all. There is no way to make it do it the other way around? so more duty cycle is less revs..?

integrale8v Posted October 7, 2013 Report Share Posted October 7, 2013 If you wire it to Aux 1 and select "ISC slave" it should be opposite. Quote Link to comment Share on other sites More sharing options...
JCE Posted October 9, 2013 Report Share Posted October 9, 2013 Cant you just swap the values in the Max Clamp and Min Clamp settings? Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 9, 2013 Author Report Share Posted October 9, 2013 Simon would it work if i chance min and max clamp? I cant wire it to aux 1, as i have a custom loom that has wiresleeves and shrinkwrap. I need to cut it all up to redo that single thing.

nissan200sx.dk Posted October 10, 2013 Author Report Share Posted October 10, 2013 simon: Can you add the slave/master selection in the menu, when using a ignition output? Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 11, 2013 Author Report Share Posted October 11, 2013 I tried to chance max and min clamp and result was it jumped between 5 and 95. No adjustment, just one or the other. Quote Link to comment Share on other sites More sharing options...
Simon Posted October 13, 2013 Report Share Posted October 13, 2013 When you power up the unit is the solenoid being held wide open? In your wiring to the solenoid you have 12V to one side and then the ECU is providing the earth with a flywheel diode to 12V Hot. Quote Link to comment Share on other sites More sharing options...
nissan200sx.dk Posted October 14, 2013 Author Report Share Posted October 14, 2013 Yes my wiring os as you describe. I will check is it is held open or not Quote Link to comment Share on other sites More sharing options...
