Help me choose an ECU

[vex]

So I found a few things that may be helpful in deciding.
The PS2k lists the following:

1. Crank Position Sensor
2. Cam Position Sensor
3. Map Sensor
4. TPS
5. Coolant Temp
6. Air Temp
7. Barometric Pressure
8. O2 Sensor
9. Road Speed

This leaves
7 Analogue Voltage Inputs
1 Digital Switched Input
3 Digital Pulsed Input

Though I know we don't need Cam position and I don't readily have access to road speed (I assume at each wheel, or do them mean the read out from the tranny?), do I need barometric pressure?

They list the following for output

1. 12 Injector Drivers--Only need 4, will show remaining in aux
2. 6 Ignition Drivers--Only need 4, will show remaining in aux
3. Fuel pump relay
4. Digital pulsed outputs x 4 + 8
5. IAC

Some questions I have though: Does the PS2K include built in controller, or if I already have a controller will it still be able to use the auto-tune feature?
