My coolant temp sensor kept reading -39.99 degrees or there abouts, this is using TunerPro R/T with the ADS from the TunerPro website. I tried searching about it, but I couldn't find anything. I used the DOS Moates software and it seemed to be reading right.

Is this a known issue and I am just blind and can't find it documented? Is there a better ADS for the $32B out there?

Thanks
