Power Fc Boost Controller Problem

[noakespg]

Hey everyone,

Hopefully someone will be able to provide some assistance and advice for what to look for.

I have the power fc and power fc boost controller hooked up as per the manual however the boost controller does not stop boost at all.

No matter what setting we put it to the boost will keep climbing until we back off.

Even when we reduce the duty to 0 and drop the desired boost level it has no effect.

The boost cut safety feature doesn't seem to work either.

The funny thing is when we unplug the solenoid and connect the 2 vacuum lines together boost holds at 10 psi flat perfectly.

Any assistance would be greatly appreciated because we have tried heaps to find the problem without success.

I have a feeling it must be something simple I have overlooked.

(Before you ask I can assure you that the boost controller setting is turned on in the PFC )

Hey,

sounds like you don't have the MAP sensor connected properly...

* do you see boost at all on the PFC hand controller? Does it match what an external gauge says?

* is the boost control solenoid functioning (does it rattle at all)?

* what ports on the solenoid (they are labelled) are connected?

Regards,

Saliya

* The boost on the hand controller is about 80 off the mechanical boost gauge.

* Cant hear any boost solenoid rattle

* COM line goes to the wastegate and NO line to the intercooler piping

MAP sensor may be it. Ill have a better look.
