Firing Order Setup

Firing Order Setup

This table is used to define the engine firing order and the base angle for each cylinder.

Most engines are even-fire, meaning that each firing event occurs at an equal crankshaft angle from the previous firing event.

For example, a 4-cylinder, 4-stroke, even-fire engine commonly uses a firing order of 1-3-4-2.

The corresponding base angles are: 0° – 180° – 360° – 540°

For even-fire engines, the Generate Base Angles function can be used to automatically calculate the base angles once the firing order is entered.

For odd-fire engines, the base angles are not equally spaced and must be entered manually, as shown below for a Dodge Viper application.
