Question: How do you measure powertrain parameters with JLR SDD software (when the engine is running)? For example, coolant temperature, ambient air temp, engine timing, etc.
Answer: From memory and with the aid of some old screen shots, on the main screen select ‘Measurement Applications’. You should then see a menu with all of the selectable options. Expand the entries to find the ones you want then I think you click on the icon with +/- on it to select each one.
When you have finished click on the icon circled in red on the bottom row in Monitor.jpg attached then where you see a black stop button (square) on that screen shot there should be a play button. When you click on that the graphs will start to be populated.
