hi, this is my first time posting on this site, sorry if i am not posting in the right category or anything like that.

I have a 1993 Lexus SC400 (1uz).

Does it have an OBD-II connection in the car or one at all? I know there is a diagnostic port under the hood but that's it.

Secondly, if it does not, I read that in the US (im in Canada so i think this applies to me, correct me if im wrong), that in 1996 the OBD-II became a standard for all vehicles there. I am wondering if I can add one, like changing the ecu with a 1996 or 1997 ecu so that i can have the port?

Thanks in advance.

Nope no ODB II port because it's ODB I. You have to jump some ports in the the data port of odbi under driver side carpet and red the CEL light pulsation.

And I don't think changing the computer is possible without swapping the whole motor because of the involvement of extra sensors for odbii.
