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.
