idosubaru Posted March 10, 2010 Share Posted March 10, 2010 97 Impreza shows 3 different ECU's for the EJ22 and it's not due to Auto verses manual trans. 22611-AC830 22611-AC831 22611-AD400 I'm wondering what the difference is and if this could be a "non-EGR" verses "EGR" difference? Myself and at least one other member are in the search for the extremely elusive Automatic non-EGR ECU set up. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted March 14, 2010 Share Posted March 14, 2010 Yeah I would probably say it's an EGR issue. 22611-AC830 has been superceeded by 22611-AC831. So there's really only two ECU's. Since they've done that, 30 & 31 were pretty much the same. Quote Link to comment Share on other sites More sharing options...

Myself and at least one other member are in the search for the extremely elusive Automatic non-EGR ECU set up. The ECU I need can be either auto or 5 speed, it would be actually any EJ motor after 96 with NO EGR would work for me. And I think all non EGRs were standards. I guess teh one I need isn't that extreme, but I don't see to many motors 2.5 or 2.2 after 96 that are non EGR Quote Link to comment Share on other sites More sharing options...
lmdew Posted March 15, 2010 Share Posted March 15, 2010 I'll keep my eye out for one or two. Larry Quote Link to comment Share on other sites More sharing options...
idosubaru Posted March 15, 2010 Author Share Posted March 15, 2010 I'll keep my eye out for one or two. Larry If you see a 95-98 legacy (legacy can be up to 99) or impreza automatic without EGR for $100 or less I'll take it for sure. I've only ever seen one, but maybe you'll get lucky? Probably take it if it's more than that too, but I'm not paying insurance prices "$500". Quote Link to comment Share on other sites More sharing options...
lmdew Posted March 18, 2010 Share Posted March 18, 2010 Found two of them today, one from a 99 and the other from a 96. 99 has 3 individual plugs that go into it. 22611 AE860 96 has the one large plug 22611 AC461 Let me know which one/s you want.
