Fuel Injector Outputs
M4 ECU
Up to four groups of injectors may be driven by the ECU.
On engines with more than 4 cylinders 2 or more injectors must be driven in
parallel as follows :
6 cyl 3 groups of 2 injectors (Outputs 1, 2 and 3)
8 cyl 4 groups of 2 injectors
12 cyl 4 groups of 3 injectors
The Injector current must be doubled or trebled as appropriate.
M48 & M8 ECU
Up to eight groups of injectors may be driven by the ECU.
On 12 cylinder engines the injectors must be driven as 6 groups of 2 injectors
in which case the Injector current must be doubled.
Ignition Outputs
The Ignition System Outputs may be used to drive many different types of
ignition modules, which are detailed in the various ignition drawings.
M4 ECU
Up to 4 ignition outputs are available for multi coil applications.
Ignition Outputs 2, 3 & 4 are shared with Auxiliary Outputs 2, 3 & 4.
Outputs not used for ignition may be used as Auxiliary Outputs.
M48 ECU
Two ignition outputs only.
M8 ECU
Up to 4 ignition outputs are available for multi coil applications.
Ignition Outputs 2, 3 & 4 are shared with Digital Inputs 1, 2 & 3.
Any pins not used as Ignition Outputs may be used as Digital Inputs.
