In OP's CSV file with PIDs, the equation for "Bypass Valve Commanded Open" should be changed from A/256 to A/255. This will give a full value of 1 instead of 0.99609375 when the valve is open, as the hex value is FF (255) when the valve is open.
FF = 255
255/256 = 0.99609375
255/255 = 1
I know Torque will round 0.99609375 to 1 when there are no decimal places shown, but I found this issue when trying to implement the following:
If you want Torque to say Open and Closed instead of 1 and 0, use this equation:
Lookup((A/255)::0='Closed':1='Open')
