INSTALLATION AND SETUP GUIDE
Fuel control module.
There are two possible ways to control fuel consumption, each of them have the benefits and
drawbacks, described below. Installer must select one of following options.
Using a vehicle’s standard fuel sensor.
There is specially designed inpu
t to read a vehicle’s standard fuel sensors.
As the benefit, this method
allows get information about fuel level without installing additional fuel sensors, this saves money and
time spent for installation. As the drawback of this method is precision of measurements - it can range
from 1 up to 10%, and it
is related to vehicle’s fuel sensor type and condition.
Usual connection diagram for standard fuel sensor.
Picture below shows typical connection diagram suitable for most of vehicles. This connection does not
require any external components.
Fuel sensor imitation mode
For some vehicles, especially latest models of construction machinery and tractors, additional resistor
must be connected; otherwise connection to standard fuel sensor may trigger fault codes on
vehicle’s
dashboard.
Resistor value depends on vehicle’s fuel sensor resistance –
it’s recommended to use resistor with the
same resistance as vehicle’
s fuel sensor or very close to this.
