I am confused by the following from this site.

1) Do the pressure sensors read boost or have to do with incoming air via the MAF?

2) If I am also utilizing the Profec E-01 in conjunction with the E-manage Main unit, do I only need to purchase the Profec pressure sensor?

Thanks

I'm not too sure, but if you are looking for the E-manage, and the E-01 to work together, their "Ultimate turbo package" seems to outline everything you will need:

E-manage PRofec E-01 Support Tool Ignition Harness Injector Harness PRofec E-01 External Signal Harness PRofec E-01 Pressure Sensor Harness PRofec E-01 Remote Switching System PRofec E-01 USB Cable PRofec E-01 Meter Cable

It is my understanding that the presure sensor is how the e manage see's boost.

It picks up the air measurement duties when your AFM maxxes out. It is also so the unit can measure MAP probably to kick in the optional subinjectors.
