VVT tuning insight - LUV 1.4

[Steelmesh]

Is it my tune, or does the E78 have both Low and Med base angle tables completely zero'd out? For Intake Camshaft and Exhaust Camshaft: Engine > Airflow > Variable Camshaft

In addition, the "Use Oil Pressure" is set to disabled, so does the 1.4T LUV use electronic actuators, that is more expensive in-lieu, so that doesn't make sense.

It definitely uses oil pressure to operate the actuators. That option in HPT is to use an Oil Pressure threashold to start the actuation instead of using RPM. Stock is based on RPM, stock Low values are 450 RPM so it'll always be active as long as the engine is running.

Yes, my stock tune has Low/Med tables set to 0. Why you ask? Look at the Method parameter which is set to Global, that means the Baro enable settings arent used and only the High tables are used for VVT operation at all times. Hover over the Method parameter and a little description will appear at the bottom of your screen, explains how changing Method changes how the different Baro tables are used.

Upside to this method is we only have 1 intake and 1 exhaust part throttle table to adjust.
