Hello there,
I got an ej9 vivic EDM with a P3X ECU. I do not really know what OBD it is, as the ECU has only 2 connectors. I‘ve got the opportunity to buy a chipped pw0 ecu but don‘t really know what I would need to chabge in order for it to work.
Would appreciate if anyone could help me

Check my OBD1 conversion article... the PW0 ECU is an OBD0 ECU and will require a similar approach. I have done such setups decades ago... but really dig into my ECU pages please.
