After last night I've realized that the rom size on the ecu is 160kb. How this is possible, I'm not sure. I received the ECU this way
... I've pulled the stock ecu from Romraider. It will not flash up. If I pull the map from the ECU, it opens fine in ECUflash but if I try to open it in Romraider it throws errors. Specifically that it's missing tables.
I've been told that it could be my cable. Although, working with the 04 ecu, I will test this.
