Spark timing advance - Kia Spectra

Can anybody tell me a way to advance spark timing for CNG use in Kia Spectra. Electronic advancer is not working up to the mark. people are telling about repositioning the VSS. is it worth trying?

What do you mean "reposition" the VSS? How do you reposition the VSS?.
The ECM varies timing based on NE & G signals, where NE signifies crank position and RPM. After start up ignition advance/control is not dependant on VSS. The VSS in conjuction with the TPS and the MAF/MAP helps in fuel metering!
