I could never find much information about the FTO and EvoScan, so I purchased on a couple of weeks ago.
I finally got it working on my PC today, so had a play around with it and the FTO.
Initially it showed I had a couple of error codes:
but after a battery reset and a good drive, so far all is good

In case anybody wants to know what information EvoScan can pull from the FTO, I have linked a CSV from a drive earlier.
There are some fields that show odd numbers, such as 255, 0.3, or just 0.
These fields pull information from other fields which the FTO doesn't provide, such as speed, barometric pressure, etc.
