Differences between ATX and MTX ECUs?

Does anyone know the difference between the automatic and 5-speed DOHC 4-cyl ECUs? Do the two ECUs have different sensors? For example, maybe the automatic has a 0-5v Throttle Position Sensorts whereas the 5-speed has one of those three position Throttle Position Sensors.

If anyone could shed some light on this, it would be greatly appreciated (and you'd be helping me make a really fast Festiva even faster )

I believe they are the same. The ATX ECU has a piggy pack controller for the ATX tranny, its called the ATCM.
