Ive had the MAC boost solenoid wired up in my car through S300 since November. Worked flawlessly for 4 months. Helped my turbo spool up a little quicker and all. So recently, I pulled my motor out, and did some work cleaning up the bay. I have the solenoid mounted to the body of my car so all i had to do was pop the 2 lines off. I left it plugged in at the solenoid, but i cut the power and ground wires off inside the car because of how i had it ran. The car was out of commission for i guess 2 weeks or so. Hooked everything up EXACTLY how it came apart. Have not changed a single thing.

I have changed nothing in the parameters. I'm thinking the solenoid might be bad. Anyone else had any issues with the MAC solenoids?

 

nope not me. ive always found it to be some type of wiring issue that a person has missed.

It was a guy on here and he went on vacation came back and all of a sudden it didnt work. Ended up being his connections.

 

I've used a lot of them, no problems here either.. About the only thing I see wrong is the vacuum/boost lines..

 

Im thinking its in the wires. Im going to ohm out each one in the next day or so.

 

i put money on it. yeah i could not understand the way your vac/boost lines

 

I have a vacuum diagram on http://www.phearable.net/tech

I hope it helps.

 

That's they way Ive had it hooked up since day one. Just for reference, is that diagram showing normally open for closed operation?

 

Open

 

i figured. thanks for the help
