the same type: induction, vapour injection (single point, multipoint), liquid injection (single point, multipoint);

                  (g) This gas fuelling system is controlled by an ECU of the same type and technical specification, containing the same software principles and control strategy. The vehicle may have a second ECU compared to the GFV parent vehicle, provided that the ECU is only used to control the injectors, additional shut-off valves and the data acquisition from additional sensors.

              6.3.6.3.2. With regard to requirements of paragraph 6.3.6.3.1. (c) and (d):

              In the case where a demonstration shows that two gas-fuelled vehicles could be members of the same family with the exception of their certified power output, respectively P1 and P2 (P1 < P2), and both are tested as if were parent vehicles the family relation will be considered valid for any vehicle with a certified power output between 0.7 P1 and 1.15 P2.

              6.3.7. Additional requirements for vehicles fuelled by LPG or NG/biomethane

              6.3.7.1. The additional requirements for vehicles fuelled by LPG or NG/biomethane are provided in Annex B6.

              6.3.7.2. For the Type 1 test set out in Annexes Part B, mono-fuel gas vehicles shall be tested in the Type 1 test for variation in the composition of either LPG or NG/biomethane, as set out in Annex B6 for pollutant emissions, with the fuel used for the measurement of the net power in accordance with UN Regulation No. 85.

              6.3.7.3. Bi-fuel gas vehicles shall be tested with petrol and either LPG or NG/biomethane. The tests on LPG or NG/biomethane shall be performed for variation in the composition of LPG or NG/biomethane, as set out in Annex B6 for pollutant emissions, and with the fuel used for the measurement of the net power in accordance with UN Regulation No. 85.

              6.3.7.4. This paragraph applies to Level 1A only.

              Notwithstanding the requirement of paragraph 6.3.7.2., mono-fuel gas vehicles will be regarded for the Type 1 test as vehicles that can only run on a gaseous fuel.

              6.3.8. Additional requirements for flex fuel vehicles

              6.3.8.1. For flex fuel vehicles, the transition from one reference fuel to another between the tests shall take place without manual adjustment of the engine settings.

              6.3.9. OBFCM

              For Level 1A only:

              The OBFCM device shall determine the parameters and store the lifetime values on board the vehicle in accordance to Appendix 5.

              6.3.10. Limits for gaseous emissions and the mass of particulates and number of particles

              The resulting masses of gaseous emissions and the mass of particulates and number of particles obtained shall be less than the limits shown in Table 1A (for Level 1A) or Table 1B (for Level 1B):
