1. Overview
EngiBOX is an Engine Monitoring System (EMS), developed especially for Rotax Engines,
displaying the engine parameters with an update rate of ve times per second and recording
160 hours of data in the internal memory. It is a rugged and reliable system designed for
xed panel installation.

Note: For connection specications see Chapter 2.
microSD card
A microSD card is provided together with the Engibox. The microSD card is a blank card
without data preloaded. The microSD card should be used for software updates and export
logged data from the EngiBOX to the microSD card.
Note: For more details see Chapter 4.
Rotation knob
Pressing the rotation knob allows to conrm a selection, while rotating the knob allows to
change selection.
EngiBOX connection board:
• 1 x Power input 10-35 VDC, free wire connection
• 4 x Thermocouple sensor input
• 2 x Resistance thermometer sensor input

EngiBOX measures the engine parameters to warn you instantly if any measurement
exceeds the engine limits and registers instantly the data on the internal memory.
The registered data can be either exported to the micro SD card provided along with the
product or send to the EngiBOX Web Portal through the EngiBOX mobile app. In this way,
data can be analyzed from home and be shared with the engine service center to receive
instant support.
Further EngiBOX features:
• Wizard to initialize the engine,
• Parameters displayed in two alternative views: graphic or numeric,
• Graph page to analyze the performance per each engine parameter (last 20 minutes),
• Clock page to show ight time, engine lifetime (Hobbs meter) and time since last
overhaul.
Note: Engine inizialization may not be needed in case unit installation has been already
performed by the engine service center or the aircraft manufacturer.

2. Installation
The installation procedure is divided in the following steps:
• Mechanical installation
• Connections & wiring
2.1 Mechanical installation
EngiBOX is designed to be installed on the aircrafts instrument panel, in a standard 3 1/8”
(79,5 mm) diameter hole. Make sure you have enough space on the front and behind the
cockpit panel to install the EngiBOX.
Check the EngiBOX main dimensions reported in Figure 2.
The instrument has to be installed from the front of the panel and screwed from behind the
panel according to Figure 3.
The screw length that need to be used for panel installation depend on the panel thickness
and is based on the following formula:
5mm ≤ l - t ≤ 8mm
l = length of the screw
t = thickness of the panel
Figure 2

User and Installation Manual - 7
AvMap EngiBOX
Use the screws and metal washer included in the box for standard panel thickness of up to 3mm. For
thicker instrument panels, use longer screws and use the formula to choose the right screw length.

IMPORTANT: Make sure you respect the screw length formula to avoid damaging the
plastic of the EngiBOX. Use light thread locker to prevent screw loosening with vibration.
Use the cutting template, included in the box, to cut out the panel. (see Figure 4)

Application: Oil Pressure (4 Stroke)
1 x RPM pick-up
Measuring range: 0 to 9990 rpm
1 x INPUT Manifold Pressure
Measuring range: 0 to 70 inHg
Usage of other instruments in parallel
• Thermocouple sensors (for EGT and CHT) and Manifold pressure input can be used in
parallel with other measurement instruments.
• To use EngiBOX RPM input in parallel with another RPM instrument depends on
capacity of the other instrument. EngiBOX applies a 100 ohm load on RPM. Verify if the
other RPM instrument is able to correctly measure RPM with a 100 ohm load applied
between RPM input and instrument ground. This is equivalent to EngiBOX RPM usage
in parallel with another RPM instrument.
• Thermoresistance sensors (for OIL T, CHT, CT and Air T) and Oil pressure sensors can
not be used in parallel with other measurement instruments.
WARNING: Thermocouple sensors must be ungrounded, not be referred to GND or negative
external power.

Connection board
EngiBOX has several sensor input ports, which can be occupied variably according to the connected
engine type. On the back of the EngiBOX there are several connections, see Figure 5.

AvMap EngiBOX
Manifold Pressure (MAP)
Connect a exible plastic tube with an inside diameter of 4mm (0,16 inches) to the EngiBOX MAP
port and to the Engines manifold pressure connecting nipple. Make sure the tube t tightly.
Note: see your Rotax manual for the manifold pressure connecting nipple position or contact your
Rotax Service Center for assistance.
Oil Pressure
The EngiBOX connection board is pre-congured to be used with the Keller type 4-20 mA pressure
sender for Oil pressure. The POIL sensor selector switch is set to “2” (ON).
Instead, if the resistive 10 Bar/150 psi VDO type pressure sender is connected it is neccessary to set
the POIL sensor selector switch to “1”. See Figure 6.

Power supply
Power the EngiBOX from an 10 to 35 Vdc supply. Mount on the power wire (RED) the 1A fuse holder,
provided in the box, to protect against short circuits.
Note: Use the Aeronautical grade wires for power supply that are supplied together with the
EngiBOX (black -- / red ++). For connection see the connection board (see Fig. 5).
