    Due to having to remap the ECU (s) because of a full exhaust , the tuner can’t write on the ECU because of the immo. He has to locate the relay and do something with it (can’t recall ), but I can’t locate it . It should be the R6 but that one is for the wipers . Any help is appreciated.

    This doesn’t really make sense- the firmware that runs the engine (the fuel maps etc that you’ll have changed to suit the exhaust) is on the 1mb flash chip on each ECU. Unless you’ve had a 360trev tune, then this chip does nothing with regards the immobiliser. The immobiliser data is held on a tiny eeprom chip on the righthand side (master) ECU. Your tuner shouldn’t have any reason to read or write to that chip.

    In practice, the only times you’ll need to read/write the eeprom is when you’re cloning an ECU due to needing to replace it.
