The FARIA MG2000 Tachometer

combines the features of an ECU serial

bus gateway and several instruments

into one unit:

• The tachometer is analog in

appearance but driven by a stepper

motor for digital accuracy.

• The high resolution LCD screen

displays information for many other

functions and the various “screens”

can be conﬁgured as the user

wishes. As received, the screens

are conﬁgured as shown in Fig. 1.

The MG2000 receives digital engine data

from the Engine Control Unit (ECU) via

the GM ALDL bus and can receive GPS

information via a NMEA 0183 connection

to a suitable GPS unit. GPS information

is displayed in the MG2000 speedometer.

Analog inputs are provided for two non-

engine sensors such as fuel level and oil

pressure.

The MG2000 provides a Faria Bus output

to allow use of various other 5, 4, and 2

inch instruments with the MG2000.

The Faria MG2000 Tachometer will turn

on when the ignition key is turned on and

will turn off when the ignition key is turned

off. The unit will power up showing the

default screen selected by the user.

Default Screens

Figure 1

The instrument has three push buttons;

“M” “Mode”, “Down”, and “Up”; that

control the functions available. The “M”

“Mode” button is used to change the

function of the LCD display and to access

submenus and adjustable settings. The

“Down” and “Up” buttons are used to

modify the settings.

In the “Normal” operation mode, pressing

the “Mode” button and then pressing

“Down” or “Up” button causes the display

to cycle between the available screens
