Default How to unlock the ecu on is250?

Hi guy! Does anyone know how to open the ecu? I mean the ecu (engine control unit) is the thing to block ur car speed in a limit. So, I wondering if someone here know about this.

Can't be done on US cars.

I believe on Japanese market models TOMs has a way to change a few limited things (like the top speed limiters) but they charge several thousand bucks for the service and it only works on japanese ECUs.
