I have a 00 civic with a jdm b18c with gsr trans, no marking on ecu, and absolutely no communication through obd port with fox well 510 elite programmed for Honda. How can this be fixed, and how to find what ecu was installed on car.???
And the plugs in the ECU look to be OBD1 plugs and that looks to be like an OBD2 to OBD1 conversion harness, possibly home made. OBD1 will not read on a scanner.
IMO there is nothing to fix, that's better than having an OEM obd2 ecu that isn't meant for that motor just so you can hook up a scan tool. The obd1 ECU is hopefully tuned. You can pull codes without a scan tool using the service jumper. Easy Google search. I would never buy a scan tool for obd1 Hondas.
Unless you are dealing with emissions restrictions...it's fine.
There are scanners for OBD1 on the three wire diag plug. The foxwell isn't one of them.
Autel MS906BT is one example.
The average Joe isn't usually going to have a 1500 dollar scanner laying around with the Honda Adapter to go with it. There is another cheaper option Hondash if I recall. Just not sure how far they got with the project.
