CrIP validation

Located in the “Ignition” menu is the test page for the “Crank Index Position”. The Crank Index Position page includes a “Test Advance” setting, this is the ignition timing value that will be locked when in this page.

With injectors unplugged, connect the ignition system. Crank the engine and using a timing light confirm that the Test Advance timing and actual ignition timing on the engine match, if they do not, alter the Crank Index Position value (this will automatically update the CRIP setting in the “Ref/Sync Sensor Setup”). 

The engine should not be placed under any load at this point.

If the engine is wasted spark it is possible for the CRIP to be out 360 degrees and the engine will still run. It is highly important in this instance that the original physical CRIP measurement is done on the engine.

Hint: If the actual advance is more than the Test Advance, the CRIP must be increased buy the number of degrees difference. If the actual advance is less than the Test Advance the CRIP must be decreased.

Once this is done the injectors can be reconnected.
