    do you have to have a key chip for the ecu to work?
    I am thinking of changing an engine from 1.4 to 2.0 will the original chip and transponder work with the 2.0 ecu
    Thanks

    No, you need the keychip and NATS IMMU box from the same car as the ECU.

    The IMMU box is a black Siemens box under the dash near the steering wheel.

    All three need to match.
