Ideally, a datalog from a car will contain EVERYTHING that you could possibly measure about that car, period. This isn't practical, but creating a thread with such a listing might be. So I'm going to try, with your help. I'll update this first post with everyone's suggestions, at my discretion.

All normal engine parameters are a given. Don't bother with the core stuff, though I may list some. Extra parameters, though, fire away.

Engine Bonus Sensors

• Oil Pressure
• Oil Temperature
• Fuel temperature in rail
• Fuel temperature in tank
• Fuel pressure at pump
• Fuel pressure in rail
• Fuel pressure post regulator
• Turbo RPM
• Wastegate position
• Exhaust back pressure sensor
• Wideband per cylinder (mostly NA engines)
• EGT per cylinder
• Ambient air temperature (normal NA IAT signal)
• Ambient air pressure (normal AAP signal)
• Pre-intercooler air temperature
• Pre-intercooler air pressure
• Post-intercooler air temperature (normal boosted IAT signal)
• Post-intercooler air pressure
• Across throttle pressure drop
• Across intercooler pressure drop
• Across turbocharger pressure gain
• Manifold air temperature
• Manifold air pressure (normal MAP signal)

Driver Inputs

• Steering angle
• Brake pedal in use/not
• Brake line pressure, front and rear
• Handbrake handle angle and/or cable pressure
• Clutch switch and/or pedal angle and/or hydraulic pressure and/or actuator angle
• Gear selection sensor

Vehicle Dynamics

• GPS positions (front and rear)
• 4 * shock pots
• 4 * wheel speed sensors
• N axis accelerometers (more than one for attitude determination)
• Gyroscope

Body Features

• Door locks
• Key position
• Window positions
• Seatbelt plugged/not
• AC on/off
• Fan on/off/high/low/duty
• Rear window heater on/off

OK, your turn! Go :-)
