Oh the ecu came with the car as a spare when I bought it. I was going to swap it back to the autronics as my mechanic can map them and not the current one that's in the car. But manage to take car back to original mapper who fixed the issue I had. So don't really need it anymore except as a spare. The ecu chip says smc v1.99 on it. The ecu seems to be 4 plug version. I can send pics if you interested.
