    Scanner IAT glitch?

    Hey guys so I have a problem with the scanner. I'm currently logging all the available channels for the IAT. When I'm logging my IAT it flashes from 32* to like 118* but when I play it back it has the correct reading on all channels except for one. Another issue is when I play it back it back the channel list I'm logging has the correct reading on IAT but the chart has a different readings on them that is about 19* to cold. Also my ambient temp is all over the place too it reads about 10* cooler then the real temp. Anybody else have an issue like this before? I was thinking at first it was my ambient temp senor was out but that doesn't explain the IAT temps or does it? Or maybe my maf sensor? The real temp on this log is around 85*. Any help much appreciated.
