So i am not worried about that light being ON during CNG run.
It possibly only means a deviation from pre-set parameters which is designed only for petrol use and it recognises CNG as 'foreign'..
Does that help ? I could be wrong
Hey - I finally went in for the conversion - the results are quite nice - in the City, the City is giving 20-22 km/kg, and on a recent Pune trip without AC, it gave 33 km/kg (I keep telling people I am getting 40 kmpl city and 64 kmpl highway in "Petrol Cost Equivalent"
I even bragged to a Honda Activa owner that my Honda is more efficient than his! )
Only one niggle remains - after I start the car, it tends to stall while switching from petrol to CNG - I have to revv it quite hard to keep it running, else the engine dies - the delay between petrol stopping, and CNG releasing, is quite high, it seems. The reverse switch (if i manually go off CNG) is slightly smoother, generally does not stall the car. Have you experienced any such niggles with your car?
