What it does
The Target Scalar table scales the output of the cam control solenoid. By default its axis is coolant temperature, so you can reduce how much the cam is moved when the engine is cold and let it do its full job once warm. The axis can be changed to any channel if you need to scale cam control by something else.
When you need it
Cam phasers are driven by oil pressure, and cold, thick oil makes them slower and less predictable. Scaling the target down until the engine is warm keeps cam movement smooth and stops the controller chasing a target the hardware can't follow yet.
What to check
- Confirm the axis channel is the one you meant.
- Make sure the table reaches full output across normal operating temperature.
- Log cam angle against target while warming up to confirm it's tracking.
