The mixture adjustment screw on the ECU ONLY changes the mixture at idle.
You need to mess with the apparent resistance of the engine temp sensor to
change the mixture under power. You could put a 2500 ohm pot in series with
it and gradually increase the resistance until the ECU thinks it is cold and
richens the mixture appropriately.
