Hey all, finishing up my 931 swap, I just wanted to know if anyone has the resistances for the stock 931 temp sensor? I'm using a megasquirt 2 and it lets me calibrate my temperature sensor (which is definitely off by the way, it thinks I'm at 140°F sitting still) it says I need the resistance at 3 different temperatures and the resistance bias.

Thanks

I kept the stock sensor for the dash gauge - it's not super-accurate anyway - and swapped in a BMW temp sensor for the Thermo-time switch, which ends up being a bolt-in swap (since the thermo-time switch is unnecessary anyway after EFI conversion).

Part # was 12-62-1-747-281, got mine from ECS Tuning, not all that expensive.

Can share the cal for that if you wish to go that way.
