Electronic Lean Burn: Description: Notes

Starting in 1979, the Electronic Lean Burn (ELB) ignition system became known as the Electronic Spark Control (ESC) system. The system is governed by the Spark Control Computer (SCC) and various engine sensors. The function of this system is to provide a method for burning a lean air/fuel mixture. See Fig 1.

In addition, the ESC system was used on 1979 Aspen and Volare models with 225" 6-cylinder California engines as part of a total emission system called Electronic Feedback Carburetor (EFC) system.
