IMPORTANT NOTICE
For good operation of the SGIS system, use spark plugs with
internal resistors; we recommend NGK, BERU.
Check the engine-battery-body ground connections; if unsure
of efficiency, reinforce with a cable of minimum 5 mm section.
It is important that the engine hood be well-grounded; if
necessary, install an additional cable of minimum 3 mm section.

Vehicle configuration is performed in two phases.
The first phase provides for entering the technical data for the vehicle;
the second phase comprises actual calibration of the vehicle.

In particular, should the RPM value not be similar to that given by the
vehicle engine speed indicator:
- shift the RPM signal pickup point
- if unsure of the specific connection, try all the leads
to the engine ECU comb one by one until the

- or connect the special AEB adapters to the ignition
coil.

FEEDBACK MAPPING (for automobiles for which there exists no
specific OBD emulator; e.g., Citroen and Peugeot)
- Emulation with the FEEDBACK system is performed as outlined below.
- Once system installation is completed (with the automobile in the
gasoline operation mode), the next step is to acquire about 40 points
distributed over the entire map. To acquire a point, simply position the
dot on the cell; as soon as the lambda probe begins to oscillate
between red and green, press SPACE to acquire the value. Once point
acquisition is completed, click “Download Road-Acquired Map”. In the
gasoline fuel mode, proceed at a steady speed to various points on
the map and check that the gasoline correction value (on the lower
right of the display) remains within a maximum value range of +/- 100.
If so, the map is good; contrariwise, any chosen point may be precisely
corrected, taking the gasoline correction value as the point value.
Example: if at a given point on the map we see a gasoline correction
value of 350, use the mouse to light the correction window and enter a
value of -35%.
When gasoline mapping is completed, it is possible to go on to GAS
mapping by setting “Lambda emulation” on the FEEDBACK screen.

Enter the CUT-OFF start delay time, in seconds. This value
affects driving quality (smoothness) (We recommend not
changing the preset value, at least initially).
- Again with the engine idling, modify the cells adjacent to the
red reference point in such a manner as to obtain more similar
values. This modification will result in greater engine stability at
idling speed. In this phase, work in such a manner as to bring
the correction close to zero, with a temperature of about 70°.
- For example: maintain a time interval of between 0.4 and 0.8
between one line of the map and the next.

Enter the CUT-OFF stop delay time, in seconds. This value
affects driving quality (smoothness) and idling stability (We
recommend selecting values in the 0.04 to 0.48 range).
Between one RPM line and the next in the interval between 500
and 1500 RPM, up to a MAP value of 1.08, maintain a time
interval between 0.1 and 0.2.

Enter the RPM for end of CUT-OFF (We recommend values
from 1400 to 1600 RPM).
If the engine stalls upon return to idle speed, use only lean
mixture or no CUT-OFF.

value very similar to that of the cell above the red reference
point at idle (in this case, cell “A”).
- For example: if the stored cell “A” value is 4.14, we will enter a
value of 4.00; this modification will improve the return to idling
speed at the end of cutoff and reduce the delay in
acceleration during gear change.

The operations for performing mapping of the SGIS control box are
outlined below.
- In order to make use of probe emulation with gasoline feedback, the gasoline map must be created
before switching over to GAS fueling.
- Start the automobile and switch to GAS fueling when the temperature exceeds 60°.
- With the vehicle idling, use the SHIFT and ARROW keys to highlight the map cells around the red reference
point.
- Check the A correction value. If this value oscillates between +/- 40 and the lambda probe displayed on
the screen changes color continually between red and green (lambda control condition 1.00), press the
BACKSPACE key to acquire the datum (if the datum is successfully acquired the cell under the dot will turn
white) and go on to recording the next point.
- If the A correction value oscillates between 200 and 100, press the ENTER/RETURN key to open the “Modify
Map Values” window, select the “Percentage” option and enter a value of -5. Press OK. At this point the
highlighted values will change and the correction will oscillate between 150 and 50. Repeat the operation
until the correction oscillates within the +/- 40 range and the lambda probe displayed on the screen
changes color continually between red and green (lambda control condition 1.00). Press the BACKSPACE
key to acquire the datum and go on to recording the next point.
- If the A correction value oscillates between +200 and +100, press the ENTER/RETURN key to open the
“Modify Map Values” window, select the “Percentage” option and enter a value of +5. Press OK. At this
point the highlighted values will change and the correction will oscillate between +150 and +50. Repeat
the operation until the correction oscillates within the +/- 40 range and the lambda probe displayed on the
screen changes color continually between red and green (lambda control condition 1.00). Press the
BACKSPACE key to acquire the datum and go on to recording the next point.

INSERTION OF THE ACQUIRED DATA
- With the automobile in neutral gear and the engine idling,
press the “Download Road-Acquired Map” button. Several
seconds later the curves of the map thus obtained will be
displayed. Calibration is now terminated; to obtain even more
precise values, repeat the operations relative to registration of
the five points (use of a greater number of points can improve
the precision of the map).
The first phase of mapping is thus concluded. The second phase
consists of manual modification of certain map values.
N.B. We recommend saving the first part of the procedure
under the name of the automobile. In case of errors in the
second phase it will thus be possible to restore the values
without having to repeat the road test.
