Hello all
I've been having problem with my RB25det swap in my s13. The swap I bought came with an AEM F/IC 6 installed and tuned. I bought a new harness for the swap and tried to wire it into the new harness but the car won't start. I believe that it's an issue with the CAS wiring on the piggyback. I wired everything stock to the ecu and the car starts but runs rough. I tried rewiring the F/IC in using this guide for a RB26
