Hello Roger:

I read your expalnation of how MS figures temp. It took a while, bit I finally figured it out. Makes sense.

It wouldn't be to hard to make a new table for a PTC sensor, but from what Eric mentions, the problem would be to compile the .inc table into the .s19 file.

That's the part ...

Ok. I'm getting what the Eric says. Makes sense to get pretty 'close' with easy therm, then tuna around the slight error.

Now to the best part: Looks like the Audi MAC 11 ECU uses a linear, positive temperature coefficient sensor for air temperature measurement.

If I plug in the values from the ...

Here's my first post, and my question!

I'm thinking that it would be easier to use MS in a 'piggy back' mode to monitor the sensor information (voltage) supplied to the existing ECU, rather than fit separate sensors for MS.

I've removed the bias resistors for the air and coolant temerature in MS ...
