Settings

These are the settings for an OEM crank in the OEM configuration. Always lock and check base timing with an analog timing light and adjust as necessary. There is always a chance the trigger wheel on the crank could have changed from its original location, the wheel was not lined up perfectly on an aftermarket crank, or the sensor location has changed due to an aftermarket block.
