A US TCU will not work correctly with a non-US ECU. The US TCU requires an atmospheric pressure signal from the sensor in the ECU. This sensor is only fitted to US ECUs. The TCU will report an error code.
You can work around this by wiring a potentiometer to the Atmospheric Pressure pin of the TCU. You can then vary the aggressiveness of the shifting by turning the potentiometer. It will select the Normal, LowPres1, LowPres2 or Power shift maps as described in the Gear Shift Maps thread. It's like having a 4 position power mode switch.
