I wanted to ask you a question, we are trying to wire up the tach output and get it working with the factor cluster (just a side note, I replaced it with the OEM digital gauge cluster). The ECU I have is the Link G4X AtomX and I got a custom harness from MRP to work for my AE86 with the 16v 4AG motor.
that tach output from the ECU is not working with the factory gauge cluster and I didn’t know if you could help guide us to the right path on wrapping this up. It’s the last thing before we can dyno the car. Let me know if you can help.
