Best Ignition Timing Light FAQ

Q: Why is setting ignition timing so important for engine performance?

A: Ignition timing dictates exactly when the spark plug fires relative to the piston’s position. If the timing is too advanced, it can cause engine knock (pinging) and damage components; if it’s too retarded, it leads to power loss, overheating, poor fuel economy, and higher emissions. Setting the timing accurately with the best ignition timing light ensures the engine runs efficiently and powerfully.

Q: What is an inductive pickup, and how does it work?

A: An inductive pickup is the sensor clamp used by nearly all modern timing lights. Instead of connecting directly to the high-voltage circuit, it simply clips around the spark plug wire (usually cylinder 1). It works by sensing the magnetic field created every time the high-voltage spark fires, allowing the timing light to flash at the exact moment of ignition without interfering with the electrical system.

Q: Should I choose a basic timing light or one with digital advance?

A: This depends on your engine. If you are setting the fixed base timing on a very old engine that requires the timing to be read directly from a mark on the pulley, a basic light is often sufficient. However, if you are setting the timing on a modern engine, a performance engine, or any engine that requires the base timing to be set at a specific advance (e.g., 8 degrees BTDC), a timing light with digital advance adjustment is essential. It allows you to dial in the required advance directly on the tool for high-precision setting.

Q: Can these timing lights be used on DIS (Distributorless Ignition Systems)?

A: Yes, most modern best ignition timing light models, particularly the digital units like the Innova and KZYEE models reviewed, are compatible with DIS and other computer-controlled ignition systems. They rely on the inductive pickup clamped to the primary coil pack lead or the spark plug wire of the designated cylinder (usually cylinder 1).

Q: What is the purpose of the RPM readout on a digital timing light?

A: The RPM readout (tachometer function) is crucial for accurate timing adjustments. Base timing often needs to be set at a specific idle speed (e.g., 800 RPM). By monitoring the RPM directly on the timing light, you ensure you are adjusting the timing under the correct operating conditions specified by the manufacturer.

Q: How do I prepare my engine before using the best ignition timing light?

A: Before setting the timing, you should always consult your engine manual for the correct base timing specifications and idle speed. Crucially, on many vehicles, you must locate and disconnect the vacuum advance (if equipped) and potentially put the vehicle’s computer into “timing mode” or “base timing mode” (often by disconnecting a specific wire or fuse) to prevent the computer from automatically adjusting the timing during your manual test.
