Did anyone ever make one of these? I wanted to include it in my new packet with all the new manuals. I just don't think anyone actually did it.

 

I did, however it's based on the analytical model.

Adaptronic gives a resistance-to-ADC formula and miataturbo has the stock sensor values somewhere.

Check my spreadsheet's "temp cal" tab. I've attached the IAT and ECT curves from the FSM. You can approximate them pretty well I'm sure.

edit: you'll note their almost identical. and almost identical to the GM sensor.

 

Got it thanks Matt.
