Can someone guide me to adjust my Honda City 2006 idsi Ignition Timing, as my car is jerking in lower rpm in cng while in petrol acceleration delay too much and one of the Pakwheeler told me that your car ignition timing is too advanced but he could not answer my question of how to adjust my ignition timing as by searching on google it says that your car electronic control unit (ecu) automatically adjust ignition timing as it got data from camshaft and crankshaft position sensors.
