turbo ecu vs n/a ecu
does anyone know the differences between the turbo and naturally aspirated ecu's? is the only difference that the turbos have larger fuel maps?

it also has control for the turbo specific functions of the turbo engine.

Right...
You can see the differences in pinouts here:
http://www.graphics.cornell.edu/~v/ecupins/
The turbo ECU has an external pressure sensor and pressure exchange solenoid so it can read both manifold and barometric pressure. It has the ability to handle the wastegate control solenoid.
I guess as a means to make sure you don't accidentally use the wrong ECU, Subaru also decided to swap the cam and crank angle sensor lines.
It's meant to use a different MAF sensor than most of the NA ECUs.
It has fuel and timing maps meant to handle a wider range of airflows, and has the means to take into account manifold pressure. The maps also are designed for the higher-flow turbo fuel injectors.
And of course, it has the pressure-sensor-based fuel cut.
I believe the Select Monitor addresses the ECU uses for onboard diagnostics are different as well.
One interesting thing is that for most years there is a different part number for manual and automatic NA ECUs but all turbo ECUs are the same.
