Boost signal

Where to get the boost signal for the map sensor of the standalone ,from the compressor nipple or from the intake manifold ?

Nobady knows?

i would say intake mani. that way it sees both boost and vacuum. run the nipple off the compressor housing to the wastegate.

But some say before the trottle body ,confused here

why do they say before the throttle body?

and is the map sensor only for boost pressure reference and the standalone has lambda control?

map sensor is for boost control by the standalone and also has the lambda control ,the problem is if you get the boost signal from the manifold it sees less boost becouse of the intercooler and the late reaction possiblty IMO.

oh ok. if it is for boost control by the standalone then yea. i would say before the throttle body. or even off the nipple on the compressor.

im talking like ive done this before. haha.

Does your map sensor set the pressure reading used on your fueling map? If so you will need it to be a vac/boost signal which means it needs to come from the intake manifold. This is how my 034 stand alone is setup.
