if i drive my car for anything more than about 45 minutes at a time, then i try to get on it my rev limiter comes on around 7,000. it didnt start doing it until i put the V-AFC on. One of my friends thinks i might have two of the wires that splice into the same wire but have to be a certain length apart and i may have them to close..i was just wondering before i went and undid all the wires to find the right one..........HELP!!

 

umm.. its very important that the wires (2xwires that splice into the ecu wire) be the right distance apart, but i dont know if thats the problem with ures. u have stock ecu right?

 

yes double check your wiring. last time i seen this problem the + and - wires werent correctly installed.
