I recently bought a used 74 1.8 ECU for a backup part if needed. I was wondering if anyone has any pinout values so I can test the ECU to see if it is good. Thank you in advance.

I have the EFI Associates testers for both MPC and AFC FI systems. Unable to test the ECU by itself, these testers require the ECU in the car with the rest of the FI system, where the testing cable is interposed at the ECU connection with the EFI harness, and the ECU (and the rest of the FI system) is tested in situ. Individual function blocks of the ECU can be verified using this tester in this way.
