if the original speed wire have being cut, then should be no speed limit on car any more.
(my pre-l2 use this method: solder a resistor in speed wire) . no more speed cut. top speed faster then myvi.
pivot speed limit remover unit oni gt 3 selection and few wiring.1 speed input, 1 speed output, 1 earth, 1 ign. installation faster then eat McD
