Dualxeon64 Posted September 11, 2020 Report Share Posted September 11, 2020 I have a 3 port 2 wire solenoid and I am trying to sort the wiring for this. I have 1 wire to pin 8 for aux3 The other wire does it go to power or to a ground? Or does it go to a di expansion port? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 11, 2020 Report Share Posted September 11, 2020 1 wire to aux output, other to ign switched +12V source Quote Link to comment Share on other sites More sharing options...
Dualxeon64 Posted September 11, 2020 Author Report Share Posted September 11, 2020 Is there anything on the ecu I need to change? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 12, 2020 Report Share Posted September 12, 2020 I would probably set the frequency to 25Hz in the boost control settings, but apart from that it will just be tuning. Quote Link to comment Share on other sites More sharing options...
Dualxeon64 Posted September 12, 2020 Author Report Share Posted September 12, 2020 So I have the power connected and the other wire to aux 3 on the ecu pin by what is provided but it shows that the boost solenoid is off. Is pin 8 the correct pin? Quote Link to comment Share on other sites More sharing options...

I have not been able to get this solenoid to work. I benched tested it and it opens and closes like it should. I have 12v to 1 wire and the other wire to pin 8 as the book says to do. I tried putting it in test pwm and nothing. I do note that pin 8 also has 12v to it. For the 91 toyota mr2 st185 is pin 8 correct? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 17, 2020 Report Share Posted September 17, 2020 Yes pin 8 is Aux 3. So if it is connected to aux 3 and you set it to test PWM and set the frequency to 10Hz, you dont hear it clicking? Quote Link to comment Share on other sites More sharing options...

I thought it might be a faulty solenoid and ordered one just in case but decided to bench test and it seems to function correctly so now I'm just lost.

Adamw Posted September 17, 2020 Report Share Posted September 17, 2020 I would suggest the next step is put a test light on pin 8, it should light up when Aux 3 is set to off, and turn off when aux 3 is set to "Test (ON)". Quote Link to comment Share on other sites More sharing options...

I will try that. Should there be power at pin 8 aux3? Right now it shows 12v Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 17, 2020 Report Share Posted September 17, 2020 Yes, the auxes are pulled up to 12V, so it will be 12V when off and gnd when on. Actually just rethinking my reply above, since I dont know what sort of test light you have, Im going to change my advice. Connect one side of the test light to +12V, connect other side to Aux 3/pin 8. Test light will be off when aux 3 is set to off, and glow when set to test ON.

Okay so the test worked on it glowed and off it was it was set to off. When set to pwm it flickered so maybe the solenoid is bad? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 18, 2020 Report Share Posted September 18, 2020 Were you using a low frequency such as 10Hz when testing the solenoid? If you just do test On/Off (not PWM) do you hear the solenoid click? Quote Link to comment Share on other sites More sharing options...

ellisd1984 Posted September 18, 2020 Report Share Posted September 18, 2020 Daft question but is the ECU connected to PC link when you're trying to test the solenoid? Quote Link to comment Share on other sites More sharing options...

Its brand new I guess shipped faulty. I'll talk to the vendor. Quote Link to comment Share on other sites More sharing options...
