MoTeC M8 - Manual (Page 4)

2 Overview
Overview
The MoTeC M4, M48 & M8 are powerful and compact programmable Engine
Management Systems or Engine Control Units (ECUs)
M4 ECU
The M4 ECU has 4 Fuel Injector outputs and is referred to as a 4 Group
Engine Management System.
M48 ECU
The M48 ECU has 8 Fuel Injector outputs and is referred to as an 8 Group
Engine Management System but is otherwise similar to the M4 ECU, except
for the following :
Two Ignition outputs instead of four.
Two PWM (Pulse Width Modulated) Auxiliary Outputs and 2 Switched
Auxiliary Outputs instead of 4 PWM Auxiliary Outputs.
No individual cylinder tables (Still does individual cylinder trims).
M8 ECU
The M8 ECU has 8 Fuel Injector outputs and is also referred to as an 8
Group Engine Management System.
The M8 has additional inputs and outputs compared to the M4 & M48.
Options
A number of options are available which allow the ECU to be configured for a
particular need and updated later if necessary.
The options may be enabled at any time by entering an enabling password
using the MoTeC ENABLE Software.
The passwords may be purchased from MoTeC.
The M4 or M8 Software Update Unit (SUU) is required to enable the
options. The SUU must be connected between the ECU and the Computer
Interface Cable. (The M4 SUU is also used for the M48).
