well i spoke to some guys and they said that if you cut the pink wire on the ecu you will get rid of your speed cut .so i decided to cut the wire .i tested it out and it still would cut at 120 or so ,reset the ecu and still nothing happened.my homy has a 1j mkiii and when he had his wired they did not connect the speed cut and his car go past 120 like nothing,im guessing i probably cut the wrong wire or this dont work on soarers .anybody here cut the speed cut wire, and was it sucessful? or did you guys jus bought a speed cut defender?
