How to use non-GM sensors?

I have MS-II V3.0 code2.34
I'm going to use VW CLT and Volvo IAT. So I have started with the coolant.
Is It just to find ohm in 3 tempratures and push it into Table Generator in megatune?
What should I set in Bias Resistor Value(ohm)?

Yes.

The default resistor is 2490 Ohms, so unless you (or someone else) changed it, that's what you use.

Ok, thanks. have not changed any resistor so it should be right then.

Just a bit more on Lances comment about bias resistors
Isn't there a note somewhere that says the bias resistor is equal to the sensor temp at 27 deg C ?????

Max,
You can do that instead of changing the temp tables, but it so easy to change the tables with MS-II that I don't think any one bothers with changing the bias resistors.

Here's a little tech article we put together a while back on getting the proper readings to enter into MegaTune....
