Hey guys and girls.
I've recently installed a Profec B Spec II boost controller on my MY96.

It works perfectly but when I installed it, I removed the factory switchover solenoid (that gold Denso one behind the airbox mounted to the shock tower under the brown MAP sensor) and replaced it with a 20ohm resistor so the ECU would think it was still there.

This was an error in judgement on my part, as I now know it's there so that when you turn the key .. it switches over the MAP sensor to sense the atmospheric pressure, then when the engine is on,
switches it back over to sense manifold pressure.

Fortunately no harm has been done - though to get rid of the Check Engine light, and have the solenoid and MAP sensor doing it's job again ..
I need to figure out how to set it up so that the GReddy boost control solenoid get's it's signals, and the factory switchover solenoid gets it's too.

Does anyone have a good diagram of how the system works, say from a manual or factory service manual? Or can I pick someones brains?
Any help would be most appreciated.
Thanks,
Ben

dude when i changed my boost controller i left the old one pluged into the ecu and left it there on the side. blocked its hoses and that was it never had any dramas.

THe new EBC shouldnt need anything other than the air hoses conected to it from the turbo and wastegate.

Please correct me if im wrong anyone just going off what i did to mine and worked great..

thanks

Tim
