Joe,

The JDM and Euro TCUs are probably the same hardware, but the software is different. Pin 4 signals the TCU to change shift maps. On a Euro TCU, you ground pin 4 to enable Economy mode. On a JDM car, you ground pin 4 to enable Power mode.

There are two ways you can make a power switch on a car with a Euro TCU:

1) Mess with the TPS signal as per the FAQ.
2) Swap in a JDM TCU and then remove the bulb from the Econ light on the dash. This will make your Econ switch into a Power switch. AFAICT the JDM TCU should work fine with the Euro transmission.

Phil.
