    2.3. Proper installation of OSCAR-N SAS ECU During the installation of OSCAR-N SAS sequential gas injection system it is suggested for the wire set to point downwards. It is also suggested that it should be placed in such a way to avoid the negative impact of high temperature and humidity.

    2.4. Selecting proper type of EG2000 GOLD LABEL injector according car's horsepower The injectors efficiency should be selected in such way so that at low and high engine load conditions the petrol injection opening time on gas should be equal to petrol injection opening time on petrol.
  • Page 9 In case of using standard valve type injectors like RAIL IG1 You can use the “Nozzle calculator” available in OSCAR-N SAS software. Attention: Algorithm assumes that reducer's differential pressure has been set at 1 bar (for LPG reducer) or 1,8 bar (for CNG reducer). Calculated values are only approximate values and it is recommended to start drilling the injector nozzles from a diameter smaller from calculated one by 0,2 mm and depending on the communicates during autocalibration eventually increasing it by step of 0,2 mm.

    If everything has been installed properly steps mentioned above should guarantee proper driving on both fuels. In more sophisticated cars there may be necessity of using features located in „Map”, „Corrections”, Advanced” and „OBD” bookmarks. Remember that during work with the system You might always refer to this User's Manual located in “docs”...
  • Page 24 Autoadaptation feature can be used for automatic multiplier's correction on higher ranges of loads in places where petrol map points and gas map points are not close enough to each other (like on above screenshot) Attention: If we enable autoadaptation it works until we will disable it (works also without ECU connected to PC) After each correction made to particular point of the multiplier, some of map points in its neighborhood are being erased to ensure quick acquisition of updated gas map.
  • Page 25 “Autoadaptations precision” -defines how many map points (from 16 points nearest to the • current map point) must be collected to make single correction to multiplier. As higher this value would be as more accurate the collected maps line until autoadaptation will make single multiplier correction.

  • Page 26: Map Panel

    3.7. Map Panel In this bookmark it is possible to adjust the composition of air/fuel mixture in specific ranges of petrol injection opening time <2 - 25ms> depending on RPM level <500-7500 RPM>. Thanks to that map we can adjust mixture by shortening or elongating the gas injectors opening time in range from –50% up to +50%.

  • Page 27: Corrections Panel

    Attention: Additive and multiplicative time corrections [ms] (from Corrections bookmark), multiplier correction [%] (from Calibration bookmark) and correction from RPM [%] (from Map bookmark) summed together give final gas injectors opening time. The corrections regarding the gas pressure and gas temperature are also being applied all the time. Therefore before every another autocalibration we will be reminded by software to restore default settings to all modified corrections.

  • Page 29 “Ignoring petrol opening signal below [ms]” -this parameter sets the minimum threshold • below which the petrol injectors opening time will be not read and not converted to gas injection opening time.
