4. Setting up the trip computer
4.1. Choosing the protocol
1. A few seconds after the trip computer is plugged in the diagnostic connector you will see "Select engine" on the screen.
· press and release € ‡ to find and select the type of the engine to which the trip computer is connected.
· In order to check that you have selected the correct protocol start the engine, press and release PAR to go to the “Parameters
display”. Press SET to select one parameter display and then pressing € ‡ check that you can see the rpm and fuel .
·2. If a wrong protocol has been chosen you should set it manually. To do this turn off the ignition, wait till the screen of the trip
computer goes black and select the protocol in the “Settings display”:
· press and hold “PAR” then tap a short press on € or ‡ until you find the line “Sources” then press and release “SET” to
confirm
· tap a short press on € or ‡ until you find the line “Protoc.” then press and release “SET”
· press and release € or ‡ to find the correct protocol then tap a short press on “SET”
· some protocols allow to choose additional parameters influencing diagnostic performance of the trip computer in terms of
diagnostics options (calculating fuel etc.).
3. Check that the correct protocol has been selected. To do this start the engine, with a short press on PAR go to the “Parameters
display”. Press SET to select one parameter display and pressing € or ‡ check that you can see the rpm and fuel. If you see
incorrect data repeat procedures 2 and 3: first you should change the protocol type, sub-type etc. (if they exist in the protocol)
and only after that choose another protocol. Check if the data of the “Momentary fuel consumption” changes when the rpm
varies. Before the calibration has been completed the figures of momentary fuel consumption can not be trusted as it requires
calibration for each type of engine.
4. If none of the trip computer protocol shows engine operation parameters correctly it can mean that the diagnostic protocol for
this particular water vehicle is not supported.
4.2. Calibration of the speed and traveled distance
Calibration is required if the external speed sensor provides incorrect speed and traveled distance.
There are two possible ways to calibrate the speed and traveled distance.
1. The user does calculations by himself and enters the value of speed correction with up to 0,1% of accuracy.
2. The user enters only the reference amount of the distance traveled and the trip computer automatically calculates the
correction with high precision. The sequence of the calibration procedure:
· Reset the GPS receiver’s route parameters.
· Reset parameters in the “Average parameters display Reset 1": tap a short press on “TRIP”, then press and release “F”
to call out the “Average Hot menu”. Select the line “Reset Reset 1 and press “SET”. Press “ESC” to exit the menu.
· Drive more than 10 km as per readings of the trip computer (Average parameters display Reset 1) and stop the car.
· Press and hold “SER” to go the Settings display.
· “SET” .Press and release € and ‡ to select the “Correction” and press to go to the sub-menu
· “SET” .Press and release € and ‡ to select the “Ref.mileage”. Press to change the value
· Pressing on € ‡ to choose the correct mileage (as per data of the GPS receiver) and confirm with a short press on
“SET”.
After performing these actions, the trip computer will automatically and precisely calculate corrections of the speed and
mileage. Also the measured mileage in the “Average parameters display Reset 1" will have been replaced with a new value
calculated with a new correction equal to the reference value. When correcting the speed readings, momentary and average
fuel consumption per 100 km, distance traveled and average speed will be changed automatically starting from the moment
the coefficient was set.
4.3. Calibration of fuel consumption
For correct fuel consumption reading, the fuel correction must be performed regardless of the type of selected protocol
(except for the carburetor protocol, if not equipped with a fuel sensor). There are two ways to calibrate the fuel
consumption:
1. .The user does calculations by himself and enters the value of speed correction with up to 0,1% of accuracy
2. The user enters only the reference value of consumption and the trip computer automatically calculates the correction
with high precision. The sequence of the calibration procedure:
· Refuel the tank until full. When refueling do not let the delivery gun shut off due to splashback until the fuel level
reaches the tank neck.
· Reset parameters in the “Average parameters display Reset 1": with short presses on “PAR” select the “Average
parameters display” then call out the “Average Hot menu” by a short press on “F”. Select the line “Reset Reset 1" and
tap a short press on “SET”. Press “ESC” to exit the menu.
· Monitoring the fuel consumption readings on the screen of the trip computer (Average parameters display Reset 1)
burn out no less than 5 liters of fuel.
· Refuel again until full tank.
· Press and hold “PAR” to go to the Settings display.
· Select “Correction” by tapping on € ‡. Press “SET” to enter the sub-menu.
· Tapping on € ‡ select the “Ref.consumption” and press “SET” to change the value.
· Tapping on € ‡ insert the amount of fuel refilled (numbers from the petrol station fuel counter) and press “SET”.
The correction will be automatically and precisely calculated by the trip computer.
