they all have different plugs on the ecu side, but all will work if you switch the connectors or use a jumper harness, you can even use a 2jz ecu with a jumper harness

You threw me off when you asked which ones are compatible with a supra. Just find out what engine and harness you have and buy the ecu that goes with it, and call it a day.
