Electronic Spark Timing (EST) circuit is shorted to ground.

If you are talking about ignition timing then the answer is easy. You don't. Suzuki's PEI (Pointless Electronic Ignition) takes care of timing the spark. If you are talking about valve timing-resubmit and I will take a stab at explaining it. There is no way to remap the electronic ignition system to change the spark timing.
It advances and retards the engine timing as needed.
The timing for this engine is electronically controlled and not adjustable
Greetings, A code 42 indicates that the electronic spark timing bypass circuit or the electronic spark timing circuit is either open or shorted. A malfunctioning HEI module can cause this.
electronic spark timing is your distributor.
Why would you want to unhook the Electronic Spark Timing?
ESC stands for Electronic Spark Control it may also stand for Electronic Stability Control. The Electronic Spark Control module will retard the timing if it detects any spark knock or pinging or even other similar sounds made by the engine such as lifter knock.
That year does not have 1. The timing is computer controlled and you MUST have an engine scanner to set the timing on that engine. A timing light will not work.
Electronic Throttle Control or Electronic Timing Control
An electronic spark module, commonly used in ignition systems of internal combustion engines, controls the timing and delivery of electrical sparks to the spark plugs. It ensures precise ignition timing for optimal engine performance and efficiency, often replacing traditional mechanical components. This module enhances reliability, improves fuel efficiency, and reduces emissions by providing accurate spark timing under various operating conditions.
