The Intelligent Ignition System controller monitors the ignition current and the peak voltage to tailor spark to the cylinder.

• A. True
• B. False
• C. Not Sure
• D. Only Some Models

Answer: (A)

Intelligent ignition systems rely on feedback from the ignition circuit to optimize spark per cylinder. By monitoring the ignition current, which reflects the energy being delivered, and the peak voltage of the spark, the controller can assess how well the spark is jumping the gap under current conditions. With that information, it adjusts dwell time, energy, and timing to tailor the spark for each cylinder across different loads, speeds, and temperatures. This per-cylinder tailoring is exactly what the controller is designed to do, so the statement is true.
