Hi guys I was having some issues about high fuel usage with my car, well you may know my story, I got an average reading of about 18Litres per 100km. Now it's getting more steady and close up to 12km per 100km but its still too much. My car was bought a month ago , so I wanted to check there's nothing at fault.
Anyways I came across this device on a chinese site . Has any of you tried this , if it indeed has an economy mode maybe would be worth the try. Or it might conflict with the ECU bricking the car?
