19/11/2017 · This Video explains how the HEI Electronic Ignition Distributor Works. For additional Tutorials visit our Website: http://www.howstuffinmycarworks.com

The ignition system is an integral part of any engine's performance, just a much as the fuel delivery is, whether it is carbureted or fuel injection. We will start out with the basic operation of the early HEI (High Energy Ignition) as it debut in mid 1974 and work toward the ESC (electronic spark control) as it appeared in 1981.

The High Energy Ignition (HEI) used on most General Motors products prior to the use of fuel injection was a hall effect type of distributor. It did away with the conventional points and condenser and used a magnetic pickup. This system consists of a star-shaped wheel on the center shaft, which passes in front of a magnetic pickup.

07/04/2017 · The ability to work on full battery voltage was made possible by the ignition module and its circuitry that used transistors. HEI uses no ballast resistor or resistance wire. In a GM HEI system, the module replaced the contacts of the breaker points and the pickup coil was substituted for the rubbing block and distributor cam.

At idle, an HEI system will experience a dwell time of 10 to 15 degrees and will increase to 30 to 35 degrees by 2,500 to 3,000 rpm. The ignition now has the output when the engine needs it–at high speeds and under load. In a points system, it would take 10 milliseconds for the current to reach maximum with a coil that has 2.6 ohms of resistance.

29/10/2013 · Car Craft tales you through the steps of how to convert a Ford or Chrysler ingition to a GM HEI for a high-performance, more-efficient ignition.

25/06/2006 · It wasn't all that long ago that GM engineers designed the original HEI system to replace the decades old points-type ignitions. In the mid-'70s, leaner mixtures demanded greater voltage and …

The GM HEI distributor uses a hall effect for the triggering and sensing the No.1 cylinder location and the rpm of the engine. It uses an ignition module within the distributor to regulate the timing curve as well. It will automatically advance the timing on acceleration a specific amount and retard the spark when decelerating and starting.

01/08/2003 · An HEI is an inductive system, meaning the ignition coil is the sole source of energy storage until the energy is released to fire the spark plug.
