ELECTRONIC SPARK ADVANCE (ESA)
The ECU is programmed with data for optimum ignition timing
under any and all operating conditions. Using data provided
by sensors which monitor various engine functions (rpm, in-
take air volume, eng. temperature, etc.) the microcomputer
(ECU) triggers the spark at precisely the right instant.
