quote from TOMS web site:
It is succeeded by the original know-how with the 16, Toyota bit computer that analysis is extremely difficult by complete analysis. Not to mention speed limitter, a change of a map, VVTi is completely controlled with other companies tuner by a test at an engine bench for impossible dozens of hours. It has largely improved torque in range of 4,000rpm to 5,000rpm. Realize the clearly different acceleration feel and performance.
There is also one in the 280T... so watch out you don't get that one as it wont work with an NA Altezza obviously.
Sounds like a full ECU so wont reset to a standard Altezza ECU.
