Full primary and secondary sequential injection can only be achieved on engines with four
cylinders or less. Wire injectors as shown in the preceding table. On engines with 5 or 6
cylinders the primary injectors will be fired sequentially and secondary injectors fired in
group mode. Engines with 8 or more cylinders must use Group Staged Injection.
Set the 'Injection Mode' to 'Sequential/Staged' when using this configuration.

Note: For information on wiring Ignition Outputs as additional Auxiliary Outputs, refer to the
section on wiring Auxiliary Outputs.
G4 ECU's have up to 8 independent ignition drives which can be used in a wide range of
configurations from a basic distributor set-up through to more complex multi-coil
arrangements. G4 ECU's support the ignition configurations shown in table below.

8.2.1 Igniter Requirements
An igniter acts as an interface between the ECU and the ignition coil(s). The Igniter is used
to drive the coil(s) by supplying a ground for the coils negative terminal. Wiring of an igniter
