97 EJ22 Impreza ECU differences - could it be EGR?

Featured Replies

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.

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.

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

I'll keep my eye out for one or two.

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". :lol:

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.
