I've recently bought a used Pfc for my r33 Gtst, also bought the map sensor, solenoid and the 3 pin wiring loom separately.
Everything is hooked up and I'm getting unlimited boost
Things I have checked:
Soldered red wire of the solenoid on to the white wire on the plug, and black to black- this should be right?
Blew through the com port on solenoid, air goes right through to the NO port when unplugged
When plugged and car idling- still blows through though with resistance
Pull out the multimeter and checked the plug, ecu side female- getting 3v on idle and constant 13v when the engine revs up a little
This explains why I'm getting unlimited boost because solenoid would've been shut the whole time
I assume that the boost controller is switched off on the PFC or otherwise I wouldn't be able to start the car according to Paulr33's guide
The PFC is the first gen, didn't come with a hand controller so I'm flying blind with the settings
Ecu wiring doesn't seem to have been touched before, other than the usual alarm immobilizer, though it was running a nissan remanufactured ECU
Solenoid is unplugged for now, so I'm just running standard boost
So question is- have I wired the solenoid wrong way round? Or is the Pfc faulty? I'm a bit hesitant in cutting the wires and resoldering it again because there's not a lot of length left. Also searched and remember someone saying that if it's wired the wrong way it just simply won't work- so you get stock boost
Any help is appreciated
