Diff. between ECU and CPU?

Is Autothority and aftermakrket? is it a CPU or an ECU?
Best to have a seprerate ECU and CPU?

Thats the ECU under the passenger side carpet. The stock one is mounted almost under the dash, you said yours was under the seat?
The ECU controls the engine spark timing and fuel delivery.
The CPU is located next to the fuse box on the drivers side. right behind the hood release. This controls all other electronics in the car (lights, p windows, security, stereo, etc.)
The Authority ECU is surely aftermarket.
