Page 25: First Start In The Vehicle
3.2. First start in the vehicle If the installation was performed correctly it you can connect main 24-pin connector to the device. Previously, connect the LCD/OLED connector. When you turn the ignition key, the display should illuminate and show the splash screen. The welcome screen is displayed for 2 seconds, then displays the default user screen (varies depending on the preferences selected in the settings). -
Page 26: Calibration Of Speed And Fuel Consumption
3.3. Calibration of speed and fuel consumption In order to calibrate speed and fuel consumption readings, two constants have to be set: • VSS constant, expressed in meters per pulse [m/imp], • injection constant, expressed in liters per second [l/s]. Calibration assistant built-in UTCOMP application will help you calculate these constants. - Page 27 You can end calibration process at any time. Run UTCOMP application, click "Help" button and go to "Calibration Assistant" tab. You can import collected data from UTCOMP or rewrite it manually (they are displayed in DIAGNOSTICS screen). First step is to calculate VSS constant which is responsible for speed and distance readings.

Page 28: Accurate Calibration - Achieving Accuracy Better Than 1
3.3.2. Accurate calibration - achieving accuracy better than 1% Accurate calibration is based on comparing real distance and fuel consumption values with values displayed on UTCOMP. You will calculate percentage difference and make correction of constants. Start UTCOMP application, click "Help" and "Measurement Correction" tab. In order to calibrate speed and distance readings, you need to enter distance counted by UTCOMP and real distance traveled by the... - Page 29 TIPS for calibration: • for accurate calibration it's recommended to make longer distance: tank to full (remember to set proper tank capacity before) reset statistics in tacho screen (distance and average fuel consumption) by long pressing SW3 and follow display instructions, travel long distance (at least 100 km or miles - you don't have to do it single trip), refuel to full and calculate real average fuel consumption from distributor data, make correction using Measurement Correction function in UTCOMP application.

Page 39: Travel Costs
3.6.3. Travel costs It is possible to calculate travel costs in TRIP screen. For calculation are used: average fuel consumption in trip screen, distance and fuel price (per liter or per gallon). 3.6.4. Black ice alert You should have outside temperature sensor connected. In the case of temperature below two degrees, the outside temperature icon will change (snow instead of clouds). -
Page 40: Trip Summary
3.6.6. Trip summary After each trip summary screen will be displayed (with traveled distance, trip time, fuel consumption and cost). You can change time for how long screen will appear (0-180s). For vehicles with LPG, summary calculations include both fuel types. In TRIP screen there is possibility to switch to current summary screen (SW3) or restore last displayed summary (SW3 once again). -
Page 41: User Defined Screens
3.6.9. User defined screens In UTCOMP application, you can define your own screen. You can decide what to display in each place. In UTCOMP-3 there is available single user screen. In UTCOMP-PRO there are four user screens (different templates). Here is an example of configuration user screen for UTCOMP-3 and UTCOMP-PRO (user-1 has template from tacho screen): Top regions (UL and UR) are single choose. -

Page 52: Appendix C - Frequently Asked Questions (Faq)
Q: Can I use my own display, e.g. a different color or size? A: UTCOMP-3 is compatible with all graphic displays with a resolution 122x32pix based on the controller NJU6450, SED1520 and related. UTCOMP-3 works also with OLED displays with SSD1305 driver. UTCOMP-PRO is compatible with all OLED displays with a resolution 256x64pix and SSD1322 controller. - Page 53 Q: Where to find the signal from the VSS speed sensor? A: If you have an electronically controlled counter (e.g., on "cable") the easiest and fastest way is to check whether such a signal is connected to the radio socket (some radios have the option volume up with increasing speed) – the ISO pin no.1, designated generally as VSS, Vehicle Speed, GALA, GAL, etc.
