I have a 2007 Cooper S and I just bought a ProSport EVO 52mm Digital Boost Gauge and an Alta Performance Boost port adapter to go with it... Does anyone know where the MAP sensor is to hook the adapter up to?

 

There are two MAP sensors --- one on top of the intake manifold, with 3 wires (accessible by removing the air filter) and one on the hard air pipe (between the FMIC and intake manifold, next to the passenger side wheel well), with 4 wires. This one is dual purpose --- pressure and temperature.

My Alta boost port adapter went on the one under the air filter.

 

Thank you so much!
