Adamw Posted May 22, 2018 Report Share Posted May 22, 2018 No it needs to be cam position with closed loop feedback, duty cycle alone is not useful with most VVT systems. Duty cycle just determines how much restriction is applied to the oil flow, which is not directly related to final cam position. If you just use say a fixed duty cycle you will get a different cam position everytime depending on oil pressure, oil temp, rpm etc. It might work if all you want is fully advanced/fully retarded and nothing in between.
