OK,

Got it, took some time but with a little reverse calculating and with good temp/resistance pairs one can use easy therm to figure out the best match of bias resistor to be used.

I am having problems getting temperatures to read correctly within Megatune.

I installed the original 2490 ohms resistors at r4 and r7 in megasquirt.

Here are the resistance and temperatures that I recorded on the vehicle between pin 20 and ground.
