Settings

Exhaust Frequency - The frequency used by the Exhaust 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.

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

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

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

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

Cam Control Target Angle Table

The Exhaust Cam Angle to be targeted by the Cam Control. Many engines will typically use more retard in the very low RPM ranges, less retard in the middle RPM ranges, and a little more retard at very high RPM.  This needs to be found with the use of a dyno. Up to 4D mapping is available.

Exhaust Base Duty Cycle Table

The amount of Duty Cycle that is required on the Selected Bank Exhaust Cam solenoid to hold the Cam on the targeted position. Up to 3D mapping is available. This is found by monitoring the Cam Control Exhaust 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 Exhaust 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 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.
