Setup of BAC Valve Idle Control
The following steps will guide you through a method to setup and tune your idle control.
• Ensure that your Fuel and Ignition maps are well tuned and warm your engine up to operating
temperature.
• Make sure that your throttle is properly calibrated so that throttle position in the engine data reads
zero percent when you are completely off throttle.
• Check all the settings of the idle controller, the above values are a good place to start.
• The engine should idle around the ‘Warm Target RPM’, adjust this value to change at what RPM
the engine will idle when warm
• Adjust the ‘Warm Start Duty’ so it is about 5 – 10% above where the BAC valve is sitting when the
idle is controlled.
