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!
