How do you identify which car an ECU/ECM came from?


Recommended Posts

I have a couple of Subaru ECU's (or ECM's) pulled from a junkyard. Is there an easy way to figure out what model/year/engine/transmission Subaru they are for?

 

For example, one ECU I have is labelled as:

DK6 7Y

22611 AD57A

JA18000 DK6 7515

 

How does one translate this info to something useful?

I found this info from a web that sells ECU's. Useful for searching and identifying ECU's (or ECM's as some people call them)

I did a search under "Part number like" and entered "AD57A" (I didn't enter 22611) and voila, I was told the ECU is from a 1998 Legacy 2.2 with left hand drive and auto transmission. This sounds correct to me based on what the seller told me.
