It is the wrong ECU. Get the right one. They are not expensive, about $100 used. Also there are rebuilt ones available for a little more.

ok i know it is the wrong one but will a turbo ecu fit the stock harness

He has a N/T car that he has turbo'd, and wants to run a turbo ECU for fuel management.

Are the ECU pinouts and connectors the same? That is the question.

Yes it will hurt the car with the n/a ecu. It doesnt have the right fuel/timing maps and it doesnt have a knock sensor circuit. So basically, you can run 35* timing at full boost with no knock control, which equals melted parts. The turbo ecu will plug right in, you just have to wire in the knock sensor, the 7th wire from the turbo mas, and the fpr solenoid.
