Below is how the ignition outputs will be allocated in the Direct Fire Ignition output mode.
Connection / Function
Number of Cylinders
ECU Output 1 2 3 4
Ignition # 1 1 st Coil to fire* 1 st Coil to fire* 1 st Coil to fire* 1 st Coil to fire*
Ignition # 2 Digital Output 1 2nd Coil to fire* 2nd Coil to fire* 2nd Coil to fire*
Ignition # 3 Digital Output 2 Digital Output 2 3rd Coil to fire* 3rd Coil to fire*
Ignition # 4 Not available Not available Not available 4th Coil to fire**
* Connected via Ignition module.
** “Coils on 4 cyl – 4 coils” setting must be enabled.
B.2.3 Waste Spark configuration
When using a waste spark ignition system, the number of ignition outputs required will equal
half the number of engine cylinders. ie,
4 cylinder engine = 2 Ignition outputs
6 cylinder engine = 3 Ignition outputs
8 cylinder engine = 4 Ignition outputs
The corresponding cylinder pairs can be determined for any engine by looking at the engines
firing order. An example using a flat 4 cylinder with firing order (1-3-4-2), the cylinder pairs
can be determined by separating the firing order in half, ie (1-3) & (4-2). The first coil pair
would be the first cylinder out of each group, ie (1 & 4) with the next cylinder pair being the
second of each group, ie (3 & 2) etc. This method will work with all even fire, even number
of cylinder engines.
The diagram below shows how the coils would be connected for the example above.
