Thanks Matt-

I am without a stim unfortunately. I can hook up a pot to the temp sensor input though, and I think get in the ball park of the same functionality.

edit: You do appear to be saying, in On/Off mode, I should be able to toggle to a steady state on the output, and in PWM mode, I'll just ...

I'm using a DIYAutoTune sourced Ms2-v3 board. I attempted the PWM mod for the fast idle.

Removed the two small transistors, jumpered the resistor, and installed the TIP120 per the diagram, along with the flyback diode.

Had some issues with ...
