FAQs

What is the timing advance key? ›

The Advance Timing/Offset Key is an essential tool that allows for precise adjustment of ignition timing on high-performance engines. The key is designed to replace the stock timing gear and provides a wider range of adjustment options. This allows the engine to be fine-tuned for optimal performance and efficiency.

Some things to look out for: Engine knocking: Engine knocking occurs when the air-fuel mixture is ignited too soon in the cylinder. The mixture then pushes against pistons that are still trying to compress the mixture. This causes loud pinging sounds to come from the engine.

This is the amount of advance at idle with the spark triggered Before Top Dead Center (BTDC). Most stock street engines call for 6 to 8 degrees of initial advance, but this is not set in stone. Engines with longer duration camshafts and other modifications often demand more initial timing.

To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you'll advance the timing by rotating the distributor counterclockwise, and vice versa.

Advancing the ignition timing could result in early combustion, which would increase in-cylinder pressure, temperature, and NO_x levels. On the contrary, retarding the ignition timing will lower the in-cylinder pressure and temperature due to an increase in combustion chamber volume and help to lower the NO_x levels.

What causes ignition timing to be off? When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
