I recently acquired a JDM WRX ECU. All I was really told about it was it was good for any non-STi EJ20. I don't own a Subaru, so I was trying to sell it, but I don't really know anything about it. The front reads the following information:

7Z

22611 AD720

A18-000 D64

7X2

UNISIA JECS CORPORATION

MADE IN JAPAN

The rear is stamped C6 and engraved RH

 

Anything anyone can tell me about this is really appriciated; I have searched the internet many times over, and can't find anything.

It's probably a JDM ECU, but short of that, there's really not much I can tell ya about it.

Already tried NASIOC, but I will try the other; thanx.

I'm guessing that's a ver.5 or ver.6, but don't quote me on that. You might also try asking the ecuteck and MRT forums. A photo of the pins might help.
