XMS4 - SEQUENTIAL INJECTION APPLICATION

This note describes how to wire up sequential injection for 4/6/8 cylinders and how to set up the unit.

 

Wiring

The following table shows the AVAILABLE amount of injector drivers for sequential use :

Unit	Injection Driver	Ignition Driver
XMS4A-4A	4	4
XMS4B-4A	4	4
XMS4B-8A	8	8
XMS4C-4A	4	4
XMS4C-8A	4	4

Sequential injection assumes an injector per cylinder! This means that the XMS4 unit will need a TDC signal to activate the sequential ops :

XMS4A-4A	Can be used for 2 cylinder or 4 cylinder sequential injection
XMS4B-4A	Can be used for 2 cylinder or 4 cylinder sequential injection
XMS4B-8A	Can be used for 2/4/6/8 cylinder sequential injection
XMS4C-4A	Can be used for 2 cylinder or 4 cylinder sequential injection
XMS4C-8A	Can be used for 2/4/6/8 cylinder sequential injection

 

 

Setup

 

 

 

The option for cam every two turns must be selected, the XMS4 will then activate the injector outputs in numeric order and not in an engine's firing order, the outputs need to be wired into the firing order, example : injector one will be wired to cylinder 4's injector.
