Howard Coleman Posted October 26, 2021 Report Share Posted October 26, 2021 i raised WG duty cycle yesterday and found no change in my boost. i did the test and heard no cycling from the MAC valve. i checked wiring and that is not the problem. it would seem to be in my sttings. i have the solenoid wired thru Aux 1. it worked with my V88 using the same harness. it is also tagged at GP output 1. perhaps it is appropriate that it is an orange wire with a black stripe... being Halloween coming shortly. i attach my map and hope you find something. i can make do with a manual boost controller for the Texas Mile if necessary. thanks 5 COLEMAN OCTOBER 25 VP.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 26, 2021 Report Share Posted October 26, 2021 It should not be set up as a GP output, you need toi go to the boost control settings and set the PWM output to Aux 1. Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 31, 2021 Report Share Posted October 31, 2021 Set up looks fine. So if you set aux 1 to test (ON) or Test (PWM) you dont hear a click at all? If you unplug the boost solenoid, do you have 12V on both pins with ign on? Quote Link to comment Share on other sites More sharing options...
Howard Coleman Posted November 1, 2021 Author Report Share Posted November 1, 2021 with the Test enabled i get 5.55 V on both solenoid wires when PWM is selected. i get zero V when Test - "On" is selected Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 1, 2021 Report Share Posted November 1, 2021 Something wrong in your wiring then, one side of the solenoid should be connected directly to a 12V ign switched source, so you should have 12V on at least one pin all the time.

Howard Coleman Posted November 1, 2021 Author Report Share Posted November 1, 2021 will check to see if an incorrect Deutsch connector was paired to the boost solenoid. it is weird though as the signal wire from the connector in use is orange/black which is Aux 1. my solenoid worked properly last year. solution is now in sight. thanks.

Howard Coleman Posted November 4, 2021 Author Report Share Posted November 4, 2021 i removed the A plug and did a continuity check re the O/B (Aux 1) wire which is used to manage the boost solenoid. continuity checks correctly. i also did a continuity to chassis for both control wires between each other and separately to the chassis and there is no continuity. it appears that i have 5.57 V from the Aux 1 pin and all other aspects of the wiring circuit are correct. why no 12V? barring some fix, i am planning to switch the solenoid control to another pin. am i correct that the pins are AMP Superseal?

Adamw Posted November 4, 2021 Report Share Posted November 4, 2021 As I mentioned above, the ecu side is fine, you are seeing the correct voltages at the solenoid from the ecu aux. The problem is the 12V side that comes from the car is missing. You should have constant 12V to the solenoid from the ignition circuit in the car whenever the ign switch is on.
