I tried it. it works pretty well as long as you don't use the NB alternator control.
the reason is this: NB alternator control doesn't change the system voltage when there's more idle load, but rather it increases MAP because the alternator just pumps up the juice to maintain steady voltage...
but the initial duty table doesn't account for MAP so... it sets the wrong initial duty.

I don't have the initial values I was using. But I tuned it in a parking lot in 5 minutes. Get the car warm, note the idle duty, put it in that spot for that MAT value. Maybe add a little bit to be safe. You can check logs for other MAT values or make some best guesses.
I run my NB idle valve at 383 Hz. Works great.

I read this - https://www.miataturbo.net/megasquirt-18/ms2-vs-ms3x-idle-duty-61914/
And then this - http://miataturbo.wikidot.com/ms2-m (part about the idle mod)
And as I understand all you need to do is take a diode from S12 to pin#3 of Q4. With banded end going to S12. Basically the "pwm idle mod" minus the whole TIP120.

I made a basemap with one, completely arbitrally.
Best thing would probably be to figure out where the PWM lands to idle at the RPM you want. and plug in that for your entire map. Then just increase it a bit as the CLT drops and decrease as the RPM increase.
It wont be until March sometime when I actually get the car out of storage and load the new firmware on it.
