Intake Cam Control

Intake Cam Control

Setting​s



Intake Frequency - The frequency used by the Intake Cam Control solenoids. Using a low frequency can give an increased usable duty range but may cause the solenoid to rattle. Using a high frequency can limit the usable duty range.

Intake Duty Cycle Min - The minimum duty that can be commanded by the Intake Cam Control solenoids.  This can prevent the Cam Control from commanding a duty that the solenoid will not react to.

Intake Duty Cycle Max - The maximum duty that can be commanded by the Intake Cam Control solenoids. This can prevent the Cam Control from commanding a duty that the solenoid will not react to.

Intake Cam Direction - Sets the direction that the Intake Cam will be driven by the Cam Control.  Intake Cams are typically set to Advance. 

Enable Intake Overall Corr - When enabled, will add an Overall Correction table to the Intake Cam tables. This allows for quick adjustment of the Intake Cam Target Angle which can be helpful for tuning experimentation.

Cam Control Target Angle Table


This table sets the Intake Cam Angle to be targeted by the Cam Control. Many engines will typically use more advance in the middle RPM ranges, and less advance at low or high RPM ranges. This needs to be found with the use of a dyno. Up to 4D mapping is available.

Intake Base Duty Cycle Table



The amount of Duty Cycle that is required on the Selected Bank Intake Cam solenoid to hold the Cam on the targeted position. Up to 3D mapping is available. This is found by monitoring the Cam Control Intake Bank 1 or 2 Output channel while holding the engine at approximately 2000 to 3000RPM (to ensure full oil pressure supply) and commanding a Target Angle other than zero. When the cam moves to the targeted angle and is stable, the amount of duty cycle that was required should be entered into the Intake 1 or 2 Base Duty Cycle table. If the Base Duty Cycle when set too low can cause delayed response in moving to the Target Angle, or when set too high can cause overshooting of the Target Angle.

PID Tuning

This allows mapping of the PID system, which controls the responsiveness of the Intake Cam Control system. In simple terms the Proportional controls how fast the system will respond relative to how far it is from the target. The Integral is how aggressive the Proportional changes are. Derivative is used to slow down overshooting the target if the Proportional has been aggressively tuned. Up to 3D mapping is available for all PID tables. Typically for Cam Control the Integral will be around half of the Proportional, and a little Derivative is required to prevent the Proportional from causing overshooting of the target. These values are found from experimentation and will vary from engine to engine.

Overall Correction



Active only when Enable Intake Overall Corr is ticked. This allows for quick adjustment of the Intake Cam Target Angle which can be helpful for tuning experimentation.

Long Term Trim

Long Term Trim Gain Table



This table controls the rate at which the Long Term control can make corrections to the Long Term Trim table. Larger numbers will learn faster but can cause oscillations, and smaller numbers will make corrections at a slower rate. Up to 3D mapping is available.

Long Term Trim Table


Shows the amount of correction the Long Term Trim is making. This table is user definable for axis values, however the axis channels are fixed to be the same as are used for the Base Duty Cycle table. This table can be adjusted by the tuner simultaneously whilst the Long Term Control is making changes. Up to 3D mapping is available.
