We would not recommend this. You would have to have the dealer reprogram the immobilizer and it is no guarantee that the USDM hardware would work on a JDM vehicle. Not to mention the off-the-shelf tunes (and even the stock USDM maps) would not be appropriate for a JDM car.

Prova of Japan used to sell a version of our AccessPORT. You might want to see if there are any of those on the market for sale and if you vehicle is supported. There are also other solutions, such as open source for Subarus that might be easier and more appropriate for your particular situation.
