That’s money I don’t want to spend yet, $1400 for a link g4 board and then $500 on tuning, I would rather just run the 8S ecu and pay a specialist to do the swap for me, I have the ecu’s and afm/maf’s on hand so I’m just trying to get the car running with the correct ecu/tune, I’m going to check the immobliser/iacv/ground connections/double check all ecu wires and check the fuel pump relay and afm/maf with a multimeter when I get home, anywhere else I should check before I give up and revert it back to the 8S ecu and F afm/maf

Guess it depemds what your time is worth

Yeah bugger that, I'd go for an Autronic or Apexi Power FC ECU. Install, tune, enjoy.
