What live data can a Control Deck key show?

A DNR Display key shows one live value from the car and updates as you drive. There are 78 read-outs, grouped like this.

• Car control: Traction Control, ABS, Brake Bias, Engine Map, Front and Rear Anti-roll Bar, Virtual Energy, TC Slip, TC Cut, Differential, Brake Migration, ERS Mode, Car Warning.
• Timing: Delta, Delta V, Safety Car Delta, Estimated Lap, Time of Day.
• Session: Fuel, Pit Fuel to add, Position, Class Position, Lap, Last Lap, Best Lap, Incidents, Session Time Left, Session Laps Left.
• Weather: Air Temp, Track Temp, Wind Speed, Track State, which shows a per condition icon.
• Tyres and brakes: tyre temperature, pressure and wear, and brake temperature, each for all four corners.
• Gaps and sectors: Gap to Leader, Interval to Car Ahead, Gap to Class Leader, and current and best Sector 1, 2 and 3.
• Driver and standings: Incidents vs Limit, iRating, Licence, iRating Gain Estimate, Strength of Field, Grid Position, Places Gained, Penalties, Track Limits.
• Pit and stops: Last Pit Lap, Last Pit Duration, Pit Stop Count, Pit Lane Open or Closed.
• Session and flags: Session Phase, Flag State, Yellow Sector, Start Lights.
• Class rivals: Class Rival Ahead and Behind, and the gap to each.

The label and value take live colours, so a delta is green or red without you reading the number. Key colour changes the border only.

A value showing a dash means the sim is not reporting it, which is normal outside a session and for read-outs a particular sim does not provide.
