ECU downloading procedure : - Follow the diagnostic tooling procedure. A new ECU or downloaded update is always configured with the following options : - SHIFT LOCK gear selection lever position. - OBD outlet (emission standard L4). If the ECU is to be fitted to a vehicle without one or both of these options: - Carry out a configuration which inhibits the diagnosis of the option(s) concerned. Pedal initialisation. (AL 4 only). A pedal initialisation must be carried out in the following cases : - Replacement of the automatic gearbox ECU. - Replacement of the automatic gearbox. - Downloading of the ECU configuration. - Adjustment or replacement of the accelerator cable. - Replacement of the throttle potentiometer. C5 - IMPERATIVE : For a certain period of time, while the ECU parameters are adapted to the gearbox, there may be an inconsistent gear selection quality. To achieve a consistent standard, it will be necessary to carry out a road test taking in frequent gear changes Hope this helps you a bit top part tells you how to get it out of park. Bottom bit is telling you about software update for the ecu. If you need any parts you know where the car is and just help yourself. Did you put the hydraulics onto your box if so you might need to update the ecu but im not sure about it mind. Think that iannez would be able to answer that one for you
