V9 Subaru Tacho output


Recommended Posts

Hey everyone, I'm trying to get my V9 EJ207 swapped 2002 WRX running on my G4+ plug and play ecu but I cant get the tach to work. I verified the pin is correct between the OEM wiring and the Link wiring. My OEM ecu drives the cluster as well. I'm curious if anyone has any idea how to get the tach to function. Currently it just does the OEM opening sweep and then rests at 0.

There is a recent revision to our V9 ECU that may mean you have the Tacho assigned to the wrong output as it now doesnt match the documented pin functions.  Make sure Aux 4 is turned off and set ignition drive #5 to tacho.
