bypass the n75 valve

[AJP]

Anybody know if its ok to bypass the n75 valve and connect a mbc straight from the turbo into the wastegate?

What will happen if i unplug it, will it confuse the ecu?

N75 needs to be plugged in or the ecu will put the car into limp mode.

IIRC MBC goes before the N75, so that once the MBC pressure has been acheived, it activates the valve which opens the actuator.

Although, In my mind, bypassing it wouldnt make a difference, as the N75 is essentially just a pressure switch which opens the actuator?

Can I ask what you were hoping to achieve by attempting this?

it would allow more boost in theroy

on later engines it would make no real difference as the ECU would just cut the throttle

The N75 is putting the car into limp mode, I fitted the MBC before the N75 and it didnt change a thing, So i have unplugged it and car seems to boost how it should do.
