    Think its the same thing mate . Years ago they would physically alter the ecu, now they just reprogram the ecu. Am sure a better explanation will be along in a second.

    - it's basically the same thing. Loading up a different software map for the car's ECU. Years ago it involved physically changing a chip on the ECU/electronics, or piggy backing another one onto the board (hence the term chip tuning). Now with the newer cars it's generally done by computers through the cars diagnostics socket, or straight onto the ECU, with nothing physically altered on the ECU or electronics.

    my cars still under 3 yr warranty, would this be invalidated?

    Basically yes. If Vx were aware that your car had been remapped and you were making a warranty claim, they could turn down the claim and invalidate the warranty - worst case scenario.

    There are mapping systems out there where you can map the car with a box of electronics through the diagnostics port - i.e. the handheld device maps the car and you then remove it, so nothing left on the car. Then you can remove and reinstall the map as and when you want when it goes in for service etc. BSR do such a system, as as far as I'm aware, it's the only one out there available for your car/engine.

    It would only affect the warranty of affected parts, ie engine etc, most other parts would still be covered.

    Yep, although they could, if they were being pedantic, say a remap could potentially affect the engine, gearbox, drivetrain and ECU (and maybe other stuff) and leave the car with a 'warranty' that was practically useless.

    They are the same thing, with the older ecu systems it was a case of taking the old eproms (chips) out and putting new ones in with the mapped software, where as the new ecu's can have new software flashed onto them via the diag port
