I live at 5000 feet elevation. I believe the load I log is corrected for normal temp/pressure. The ECU uses uncorrected load for spark and vct calculations. So this makes datalogging and tuning a little difficult since I have to guess what load the ECU is using.


When I had my NC miata, a similar issue presented itself. LoadAbs (OBD) = (AirDensity * LoadScaled) / AirDensityNTP
where airDensityNTP = 0.0012, and LoadScaled = load corrected by the load scaling table.

So, in short, I believe the OBD load pid is corrected. The ECU uses uncorrected load for spark and vct calculations. So this makes datalogging and tuning a little difficult since I have to guess what load the ECU is using.

Can we try and get an uncorrected load to log?

What you're basically describing is pretty much the difference between calculated and absolute load.

only absolute load is available to log. It would be nice if calculated load was added then.
