Universal Trip Computer (UTCOMP)

   Universal Trip Computer  (UTCOMP) made by Telwis is used to monitor technical state of passenger car. The UTC takes information from main sensors of the car then processes data and sends to the LCD/OLED screen with user friendly interface. UTC does not interfere with car electronics in any way. It can be installed in each car with electronic injection system (petrol engines, also the ones with LPG, and some diesel engines). UTC is known also as UKP on polish market.

Main unit functions - in shorcut:

• vehicle speed (km/h or mph),
• fuel consumption (real-time and average),
• tachometer, trip, mileage,
• temperature measurement,
• acceleration measurement,
• servis/inspection,
• battery voltage measurement,
• the ability to connect up to two analog sensors (eg. lambda oxygen sensor, wideband oxygen sensor, pressure sensor etc.),
• and much more - details below.Q

To accomplish basic functions, only two signals from vehicle sensors are required (speed sensor and pulse injection) - details in user manual.

Unit functions:

• vehicle speed (km/h or mph),

• real-time fuel consumption (units: l/h , l/100km , km/l, gph, mpg),

• average fuel consumption (l/100km or km/l or mpg),

• distance,

• amount of fuel in the fuel tank,

• estimate distance to refueling,

• independent daily/travel counter (travel timing, average speed, max speed, distance and average fuel consumption),

• full support for cars with LPG system (independent consumption and distance measuring),

• date and time,

• temperature measurement (inside and outside),

• user temperature – analog temperature sensor can be adopted (typical coolant temperature sensor can be screwed into engine cylinder block, engine head or oil sump),

• automatic acceleration measurement with user defined range (e.g. 0-60 mph, 60-120 km/h etc.),

• the ability to connect up to two analog sensors (max 0-5V) and draw their signal on the display (oscilloscope), eg the lambda sensor, wideband O2 sensor, pressure sensor, TPS, etc.

• support for wideband controller of oxygen sensor (0-5V, the ability of calibration U(AFR) linear function) – AFR measurement,

• support for vacuum/boost sensor (0-5V, the ability of calibration U(bar) linear function) – BAR or PSI units,

• cooling fan status info (on/off),

• headlights reminder,

• battery voltage measurement,

• adjustable lcd brightness,

• inspection/service reminder,

• car mileage,

• information about black ice,

• temperature alert (sound buzzer warning) – if temperature from analog sensor (eg. coolant temperature, oil temperature etc.) is to high (user own level setting is possible),

• additional user screen – fully customizable,

• possibility to enable/disable any screen,

• possibility to change units (metric/imperial),

• possibility to change font style,

• user own welcome screen setting is also possible,

• menu language: english, german or polish,

• software language: english or polish,

• communication with PC using USB interface (PC application is working on Windows XP, Vista, 7) – possibility to change all settings using PC.

Software:

 To setup all parameters PC desktop with USB socket and UTCOMP application can be used. Main parameters may also be set in dedicated setting mode of UTC on display (no need to connect UTC to PC). The application works under Windows XP, VISTA, 7.
