Speed Restrictor Problem

Can anyone offer any advice. Im based in the UK and to beat the queue imported a 350 (Fairlady Z) from Japan. Ive taken the car to many import specialists but they cant find a way of removing the speed restriction. So im limited to 120mph.
Has any one else had this problem and solved it. Any advice would be really appreciated.

Technosquare here in the U.S. has cracked the code on the '03 models and is just about to do so with the '04's as well. I don't know if the Japanese version of the ECU is the same as the American version or not, so I don't know if Technosquare could help you out or not.
