For sale M2 ECU for 93+ FD's. This is a re flashed stock ecu, plug in and go. It is off a car that had a after market intake, down pipe, cat-back and large SMIC. Hard to find piece that people still look for. I am posting it here first then on Friday on the Rx7 club forum, hope to sell to some one local. This ECU was about $750 new, I would do $300 or best offer
