Vega MAP-3
Manifold Pressure, RPM and
Temperature Indicator
Operating Manual – English 1.03
Introduction
The MAP-3 is a 2 1/4” (57mm) sunlight readable Manifold pressure indicator which can simultaneously display RPM and
temperature from a universal RPM and temperature input.
The manifold pressure display is also available in the form of a scalable analog bar graph, if the RPM input is not
displayed.
The MAP-3 also has a Hobbs meter (can be set to the current engine time) which is password protected, an engine
running timer / flight timer and a programmable maintenance timer to schedule routine engine maintenance.
The MAP-3 also features a programmable low/high alarm for manifold pressure, RPM and temperature. A handy magneto
check function is also available to easy diagnose magneto problems. The MAP-3 also records the maximum manifold
pressure, RPM and temperature reached in permanent memory.
The MAP-3 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This
allows for easier installation as the RDAC unit is normally mounted in the engine compartment.

transistor switch to ground with a maximum rating of 0.25A DC. It is possible to wire the alarm contacts of several
Stratomaster instruments in parallel should this be desired. To avoid false activation of the alarms, the alarm function is
only active 10 seconds after the instrument has powered up.
9 Firmware Upgrading
The MAP-3 can be upgraded in the field by connecting the RS232 port to a PC and running the firmware update program.
Note that only the RS232 port can be used to upgrade the firmware.
Please see the Vega firmware upgrading document for more information.

10 Installation
Manifold Pressure Installation
Standard polyester or silicon hosing with an inside diameter of 3-4mm is suitable as pressure hosing. For high pressure
applications the hose should be clamped onto the connector to avoid it slipping off due to expansion of the hose. For
applications where a pressure leak may prove troublesome, such as a typical engine manifold application, a restrictor
valve should be inserted into the hose so that only very little gas leakage will be present in a case of failure or if the
instrument is removed with the engine running.
In the case of the 912 and 914 Rotax engines there is a pipe connecting the two manifolds where this connection can be
made.
RPM Installation
The RPM input is quite universal. The RPM input can be used with signals from about 5Vpp to as much as 100Vpp. The
input is also AC coupled for easy installation. A noise filter is included that results in the input ignoring any high frequency
noise signals as long as this is below the detection threshold of about 2.5Vpp (Please see dipswitch settings below)
The input impedance of the rev counter input is approximately 10Kohm. You can use series resistors as well as load
resistors for applications that have unusual signals.
The 220Ohm ballast resistor can be connected across the RPM input to ground to reduce noise or secondary pulses on
the RPM line (This is often used with Rotax engines). The ballast resistor must not be inserted for direct magneto pickups
as the magneto pulse may have low energy in particular at idle.
After you have connected the RPM input terminals to the signal sources you will need to set the number of pulses per
revolution under the “RPM SETUP” menus. The calibration itself depends on your engine and rotor type and what kind of
signal you are using.
Installation of the MAP-3 is quite straight forward in most cases. The drawing in section 10.3 shows a typical MAP-3
installation. Please see the engine RPM connection guide for connecting popular engine types to the MAP-3.
Adjusting RPM sensitivity
The MAP-3 has a sensitivity adjustment trimmer at the rear of the instrument. Adjust this trimmer using a small
screwdriver such that you get stable RPM readings over the entire RPM band of your engine. If your sensitivity is too
high, you may get unstable RPM readings (usually at higher RPM as electrical noise in the ignition system increases). If
the sensitivity is too low the RPM reading may remain at zero. Fully clockwise = maximum sensitivity.
RPM Input Dipswitch settings
Setting dipswitch 4 to the “ON” position (default) enables a high frequency filter in the
RPM signal path. Some installations (direct coupling to a Magneto device for example)
will require this to be switched “OFF”. Dipswitch 4 is the closest switch to the edge of
the PCB.
Vega MAP-3 Operating Manual
Page 22
External RDAC (Remote Data Acquisition) Connection (Optional)
The MAP-3 can use an external RDAC unit as the source for the RPM signals. Using an external RDAC may be beneficial
as it will reduce the wiring from the engine compartment to the cockpit. Only the CAN High and CAN Low connections
need to be made between the RDAC unit and the MAP-3 in order for this to work. Select “RDAC” for the data source in
the “RPM SETUP” menu if using the external RDAC option. The RDAC unit is optional and is purchased separately.

10.3 Connection Diagram
The use of an external 1A fuse is recommended. Connect the supply terminals to your aircrafts power supply. The MAP-3
can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop
below 8V during operation as this may result in incorrect readings.
Please note: The +5V Sensor power output line is unprotected and intended only for the supply
of a hall-effect, optical or gear tooth sensors. Connecting any voltages (such as the 12V supply) to
this line could destroy the instrument. The +5V line may supply currents of up to 50mA. Should
your sensor require greater currents you must supply it from another source.
Please note: It is essential that a single wire be connected from the minus terminal of the
instrument to the engine block. This wire must not be used to share currents with other electrical
users as this can affect accuracy of readings.
