One for the more technical minded. My JDM is frustrating. It's a 1998 and that appears to be a year when Japan was using OBD1 & 2. Just to be annoying. I really want my car to be OBD2, but I have a sneaky feeling it's OBD1. Anyone know of a full proof way to tell for sure? Without a reader, 'cos I dont have one yet (or easy access to one). If it's OBD1 does anyone know of a way to convert to OBD2?
