1. Principle of operation
The signal from the MAP sensor is read by the STAG TUNING module and transmitted to the ECU with a
reduced value as set in the software, e.g. if the max. pressure signal is 3V and it is reduced on the
application map by 0.5V, the ECU unit tries to reach 3V and the resulting MAP value will be approx. 3.5V.
The STAG TUNING kit can work with two MAP sensors at the same time. Most cars are provided with only
one sensor of that type, but there are vehicles with two sensors. Channels to be emulated are selected in the
application.
STAG TUNING is a safe device provided that the user uses it reasonably and does not overload the engine
continously.It should be noted that excessive overloading the vehicle can cause damage to mechanical
components of the engine and the drive system.
2. Installation instructions
Terminals of the STAG TUNING module should be connected to the MAP sensor or fuel pressure sensor on
the Common Rail. For dedicated harness types it is only required to disconnect the sensor plug and replace it
with a corresponding tuning module connector.

If a dedicated wire harness is not available, identify ground and 5V supply lines in the emulated sensor plug
and make a connection. Cut the ECU signal line wire and connect the yellow line on the sensor side and the
green line on the ECU side.
The STAG TUNING kit is supplied with +5V from the MAP sensor line. Do not connect an additional power
supply line. Install the kit away of heat sources and avoid water contact, e.g. when washing the engine!

4. Using the software
Start the application and select the correct emulation channel by choosing a respective tab on the top bar.
For a single MAP sensor configuration it is recommended to use channel 1. Channel 2 should be used only
for the second MAP sensor (if installed).
Following channel selection, an orange line will be displayed with the option to add curve points by the user.
Currently active point turns yellow. Move the selected curve range down to reduce the value of signals sent
to the ECU. The exact value of emulation per point is presented in the table in the top right section of the
application window.
The cursor on the multiplier indicates the input voltage (from the sensor).
A new map is created by adding a few (or more than ten) points and defining the reduction range for voltage
values. It is recommended to save a new map on the PC.
In order to verify system operation and the new map, check the maximum deviation of the cursor (blue line)
to the right before and after modifications on the emulation line. If the vehicle is equipped with an autogas
fueling system, the effect can be noticed by observing the MAP rise in the application.

A new curve point is added with a right click. Points are activated by selecting them with a left click or with
ctrl← /ctrl→ buttons used to switch between the points.
The “Save” button is used to save the curve (map) profile to a file.
The “Load” button is used for loading a selected, previously saved map.
The “Clear” button is used to reset the curve line profile and start again.
The “On/Off” icon is used to toggle signal emulation between On and Off.
A PC connection status message is shown in the bottom left section of the screen.
