The Laguna board

Laguna Seca is the home track. Every car I pick up gets taken there, and its best lap goes on the board. The crossed-out tape is the first lap in that car. Each game gets its own board. The physics are different, so the times never mix.

Bars: time Forza loses (orange) or gains (blue) in each corner. Speeds are the slowest point in that corner, PC2 / Forza. The biggest gap is T5. Forza's lap is from Nov 14, so expect this gap to shrink with seat time.

Records

Best valid lap at each track. Laps cut short, invalidated by the game, or thrown out for an off don't count.

The rig

Nothing exotic. The point is what the data says, not what the gear cost.

The rig: Logitech wheel and pedals on a fold-out stand, H-shifter on the right, monitor and a tablet dash on the desk
The actual setup. Tablet shows the last lap: 1:24.154 at Willow Springs.
Game
Project CARS 2 on Xbox
Wheel
Logitech G920 on a fold-out stand, three pedals, Driving Force shifter
Braking
Left foot. Brake sensitivity raised to 80 so hard stops take less leg.
Logger
Mac mini on the home network, catching the game's telemetry broadcast
  1. The Xbox broadcasts telemetry. Speed, inputs, gear and position, many times a second.
  2. The Mac mini logs every lap. Sectors, valid or not, where the game flagged track limits.
  3. The coach reads the laps. Time lost per corner, coasting, spins, traction control cutting in.
  4. The session lands here. Records update on their own.
