Perfect Power Application Notes. |
Application Note : AN 4 |
This note describes how to wire up sequential injection for 4/6/8 cylinders and how to set up the unit.
Wiring
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.
