Sorry to bump this old thread but I'm interested in understanding how the EPAS assistance % calculation works using road speed and steering torque inputs. At least that's what the MGF manual says happens. Presumably this is coded into the unit.I don't think that EPAS has any way to adjust anything in software. pscan basically offers the same features that the factory T4 has.
pscan is reverse engineered from the factory MG Rover diagnostic tool (T4). I can only implement features in pscan that MG Rover put into the T4.
After you enter the EKA you have to wait for at least five minutes (but less than ten minutes) before you open the door and start the engine.
