DESCRIPTION

MSD Holley part number: 85141

Haltech does not sell this part.

This distributor plug is equipped with an adjustable Hall-Effect Cam Sync Sensor for fuel injected engines. The Cam Sync can be adjusted to achieve the proper lead time required for the particular ECU being used.  It is used to provide a Home (Sync) signal in conjunction with a crank trigger to allow cylinder identification, which in turn allows sequential fuel injection and direct fire ignition.
