Legacy777 Posted January 27, 2004 Share Posted January 27, 2004 OBD2 is the second generation computer.....little more complicated, and has better diagnostics. See my reply to your other post.....check out some of the other boards....the bbs is a good resource.... Quote Link to comment Share on other sites More sharing options...
Marnix Posted February 1, 2004 Share Posted February 1, 2004 I have done a normally aspirated EJ20DOHC conversion in my MY92 Legacy. But I have retained the car's original wiring and electronics, I just modified the engine harness to suit the different locations of sensors and actuators on the EJ20DOHC manifold. For me, that was the easiest option. In the end it doesn't really matter what hard ware you use, EJ22 and EJ20 engines can run on the same computer without problems. Only downside is, that the JDM EJ20 DOHC engine can rev up to over 7500 rpm, but my Euro ECU won't allow it to go beyond 6700. I have no experience of OBD2 computers. Good luck.
