This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

What does cam timing affect?

  • Begins Intake Event Sooner.
  • Open Intake Valve Sooner.
  • Builds More Low-End Torque.
  • Decrease Piston-Intake Valve Clearance.
  • Increase Piston-Exhaust Valve Clearance.

How do I test my cam timing?

To find exact TDC, first set the dial indicator to zero at the point of highest piston travel. Next, turn the crankshaft counterclockwise about 90 degrees. Then, slowly rotate the crankshaft clockwise (the normal direction of engine rotation) until the indicator is . 030″ below the TDC (zero) setting.
