ok quick question what are the diffrences between the california verisons of the fd and the non cali verison and can either ecu be used in either version thanks

EGR and emissions stuff

the only difference that matters is the 93, the ca has the egr valve with the position sensor, the rest of the world doesnt. so the cali 93 is like all the 94's.



so you cant put a cali 93 ecu or any of the 94 ecu's into any other fd without getting a code 16 check engine light
