How does the computer set the ignition time?
As a result, the computer will send a signal to the ignition coil at the indicated time; in the timing map. Many people will also call this, the (ESC) module or the ignition module. The ignition module works together with the computer to set the engine’s ignition system; for the best performance and efficiency.
What do you need to know about ignition timing?
They include the engine power, torque, fuel economy, and also engine’s life to some extent. Modern engines’ control unit uses a computer to control the ignition timing more precisely. The earlier generation cars required the driver to control or adjust the timing as per the driving conditions.
When was electronic control of ignition timing introduced?
Electronic control of ignition timing was introduced a few years later in 1975-’76 with the introduction of Chrysler’s computer-controlled “Lean-Burn” electronic spark advance system. By 1979 with the Bosch Motronic engine management system, technology had advanced to include simultaneous control of both the ignition timing and fuel delivery.
How does the ESC module change ignition timing?
Under heavy load, the module will advance the timing to increase power and will, retard it at low throttle. Furthermore, the (ESC) module makes these changes automatically and smoothly. Almost, to the point where they are virtually unnoticeable.

What’s the ignition timing for a Drag Race Engine?
Ignition timing is a tuning tool for professional Top Fuel drag race engine builders. The spark advance in a 10,000+ hp nitro-burning engine is typically as follows: Idle/staging is typically 55 degrees to ignite the cylinders with a rich idle mixture. Launch typically 50-53 degrees adjusted for an optimum power at launch.
Where are the timing marks on an engine?
The engine-makers normally punch the timing marks on the vibration damper at the front or on the flywheel at the rear of the engine. At times, these marks are located on the crankshaft pulley or the largest radius that rotates at the speed of the crankshaft.
