All pre 2000 AUDM ECU's used the DLC port. We started to see the OBDII port after the 1998 range of cars.

The popular OBDI ECU's are from the Civic and Integra range from 1992 to 1995. Although we call the next era OBDII "post 1996" they still used the DLC port and not the true OBDII port.


Good luck with your development.
