Theoretically it would be possible to delimit your car with this, but in reality unless you know what you are doing, it isn't going to happen. These ECUs have many layers of protection and are extremely complicated to set up.

It is probably worth spending the extra money and having it done professionally. If you mess up the programming, you won't destroy the ECU, but it is a huge pain to set things straight.
