conversion techniques from petrol to cng.
1. Automatic Conversion to CNG on water temp : Start ur car normally and ur car will autmatically convert to cng according to water temp.
2. Start on CNG : Turn ON the ignition and press and hold the CNG switch for 5 seconds then u will see CNG lights turned on continously (instead of blinking) start ur car on CNG.
3. Start on Petrol convert to CNG on first 5000rpm : Start ur car on petrol, click the CNG button and then move the RPM to 5000 it will convert to CNG.
