Good Day!
"I used a commercial VSS re-calibrator to modify vss signal only." Could you be more specific? Jim doesn't mind at all if we mention product names, as long as we're not hawking them.
Hacking the VSS signal looks like it would NOT be a resistor or pot situation - from a quick glance, that signal is a frequency that would have to be multiplied or divided to hack (clarification please).
Blessings!
