Hier mal die Liste als Anhaltspunkt, die ich direkt aus einem Post von Alex/Stratified herauskopiert habe.

3. A basic set of parameters to log are these:
Accelerator Pedal Position (The throttle pedal position. This is not the same as the throttle plate since the car is drive by wire. This is just what the driver is doing with the pedal)
Actual AFR (Yes the car comes with a stock wideband O2!. This is the actual AFR. Lower numbers are richer, higher numbers are leaner)
Airflow Mass (The Focus ST uses speed density to estimate actual mass airflow using its pre and post throttle pressure sensors. It is a calculation based on a model, not a direct measurement like MAF based cars)
Boost Pressure Actual (Boost measured at the manifold)
Charge Air Temp. – (CAT) (This is the temperature measured AFTER the intercooler before the throttle body. If too high power will be reduced and it tells you if your intercooler is overworked)
Coolant Temperature (Important for the car to be warm when logging. ECU applies compensations based on coolant temperature)
Engine Speed (Engine RPM)
ETC Actual Angle (The throttle plate position angle)
Fuel Rail Pressure Actual (What pressure the injectors are seeing. This is important that it stays constant at WOT around 2100-2200psi)
Ignition Timing Corr. Cyl (1-4) (This is where the ECU pulls timing mostly due to knock. If you see large negative corrections you need to adjust the tune for the fuel you are using)
Ignition Timing (Cyl 1) (This is the amount of timing advance currently running after all reductions are applied)
Load Actual (Amount of load the engine is seeing. This is related to airflow and engine speed and is used in a lot of engine calculations)
WGDC Actual (Wastegate Duty Cycle - this is what controls your boost pressure)
STFT (Short Term Fuel Trim - these are quickly changing corrections to the fueling mixture based on the feedback from the wideband O2)
LTFT (Long Term Fuel Trim - these are learned correction factors based on feedback from the wideband O2)
A more advanced list is this:
- Accel Pedal Position
- Actual AFR
- Boost Pressure
- Charge Air Temp.
- Coolant Temp.
- ETC Angle Actual
- Engine RPM
- FRP Actual
- Ign Corr. Cyl1
- Ign Corr. Cyl2
- Ign Corr. Cyl3
- Ign Corr. Cyl4
- Ign Timing Cyl3
- LTFT
- Load Actual
- Oct Adj Ratio Lrn
- STFT
- WGDC Actual
