Still thinking about being able to connect to Omex ECU for proper diagnosis. There is a code about on this forum which may unlock the software but as we have discovered it doesn't seem possible to connect the ECU using the obd port. The Omex ecus connect to their software using RS232 so I am thinking that the RS232 signals must be presented on the OBD type connector. Work out which ones then connect an USB to RS232 adapter and maybe we are in.As I understand at higher revs the ECU is in open loop anyway. So this decision is based on the o2 sensors signal being way out of range which implies one/both is sending within range but wrong values to the ECU?And no Nigel I don't want to buy a pair of carbs off you. Yet.
