Power fc boost kit question??? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

1997silvia · 06-22-2010, 01:34 PM

i have a s13 sr with gt28rs turbo 550's, pfc d-jetro, and some other things, but i recently got it running pretty good and had to put a new wastegate on it because the old one was leaking, did that and all it wants to run is 10psi just off the wastegate no matter what setting in my commander i have it on just 10 psi, pretty sure its wired correctly into the ecu and i have the vac lines correct too. i have tried all kinds of boost settings but no change
any help greatly appreciated!

With ignition on engine off, blow air in your apex map sensor (with your mouth not 100psi from air hose), solenoid should clicks loud.
if not, check the wire for power.
It should have 12v to one and blinking ground on other with pressure in map sensor.

i will try this today, so blow in the map and the boost solenoid will click or that map clicks?

Boost controller solenoid clicks.
It should be connected to your waste gate.

any other suggestions?
thanks guys

So now, check for power and blinking ground.
It should have power with ignition on.
And if you don't have power on this one, your O2 heater is not getting power also.
It's common harness problem. someone didn't wire it right.
