On my 89 BMW 535i, where does the computer chip go?

I have a computer chip for my '89 535i BMW. I don't see where it goes. Do I have to disassemble the ECU? I thought it would be a plug and play scenario like on a GM car that I had done previously.

Have you found the ecu? It's under the hood on the passenger side.

Once you open the black cover you can remove the ecu. Then you have to take the metal cover off and you'll see the circuit boards. Replace the stock chip on the board with your new one.

Hope that helps,
