They're obviously pin-compatible with the pcats tuners I don't think they are pin compatible with a factory tuner, but they are functionally compatible and physically somewhat smaller, so it should be easy to graft one in with about 10 wires. I can send datasheets on both modules if you want, but I don't have a factory tuner to check it with. I DO have the circuit diagrams for both...
