Sounds like we've nearly come to some agreement about how sol C works.

I added logging to the tcuscan program and took a 10 minute drive at lunchtime. Unfortunately I behind traffic the whole time and didn't find an empty bit of road where I could get up some speed.

The CSV file can be loaded into any spreadsheet and graphs can be plotted.

It takes 3 seconds to read all of the parameters from the TCU. About 0.2 seconds per parameter. This leads to a problem with consistency because the parameters are not being read at the same time. If you compare the "gear" column with the "sol 1" and "sol 2" columns then you will see what I mean. I could improve things a little by changing the order so that related items are read one after another. But in order to increase the resolution it will be necessary to read fewer parameters.
