A dead short on the sensor, or fooling it with a higher voltage, may lower your idle further.
Just a guess.

That's a great question that I don't have an answer to. What I do know is that the voltage at the ECU's ELD signal pin reads around 4.5V with the ELD unplugged and drops when the ELD is plugged in or when electrical loads are applied. The higher the load, the lower the ELD voltage.
Now I need to figure out how to keep the ELD plugged in and functional while still disabling low charge mode. Perhaps removing the alternator control wire from the ECU connector would accomplish that goal since low charge mode is activated by shorting the control wire to ground. But whether that method would set a code and/or create another issue I have no idea. I guess there's only one way to find out.
