I had lancer GV company fitted CNG. Now removed because turbocharged it. I use to get 100-110Km with ac in traffic of Karachi. Yaar I can't understand how does the insani style on CNG may vary the mileage ? I am not talking about petrol. Until and unless you install CNG injectors controlled with ECU according to RPM ? Because in normal CNG kits in which venturi is used there is just one flow of CNG weather you drive at high rpm or low rpm dosage remains the same. If it was controlled by CNG injectors so you can say it vary because at high RPM injector would open high CNG dosage. But in venturi its not the case . Please clear it.
