I know the E40 ECM doesn't have the hardware to control an IAC but assuming I just wanted to set idle speed with the set screw like a carburetor could you get an E40 ECM to work properly with drive by cable?

Will on TPS sensor work for this? Or do I have to feed the ECM two TPS sensors? Is this even possible?
Also worth mentioning I'm running a 4l65e automatic which the stock TCU controls
