Sorry leegil, that happens not to be the case - you can ask the UK seller or the local distributor, John, if you like. The SRS-II is a rebadged Alientech PowerGate S, just like my Viezu V-Switch, and it gets locked to the car when you do the original ECU download.

John or DNA Tuning in the UK can reset it but they would only do it if you are on-selling the unit. Once this has been done and another car downloaded, you would not be able to use the SRS-II to reflash your car.
