Investigating the device that you have paid for is obviously legal.
Despite of whether it is a car, a PC or a metal hammer.
I have a right to burn my car, crash and smash it to floatsam and jetsam.
Why i cannot look what is inside the "black box" of silver ECU
If it is illegal then how call the fact of selling a couple of bites through the j1962 OBD-II socket for the 1000$ ?
And they ask a payment from every reflashed ECU!
May be they want all the cars to pay them for the atmosphere air that feed our engines?
