Hrm...the plugs are similar to the supra 1jz ECU but the supra 1jz has 4 plugs and a flying lead, and that ECU only has 3. It's definitely not soarer or chaser either. It's also not a vvti ECU. Frankly, it doesn't seem like a JZ ecu of any kind.
EDIT: It looks alot like a 3s-gte ECU, the connectors match.
