BCC [Boost Cut Control] is NOT the same as a speed limiter defencer! I wasn't aware of a speed-limiter in the MkIII ECU. FWIW: The Apex-i Rev-Speed Meter has a speed limiter defencer- it just intercepts the speed signal to the ECU.Thanks old guy, that is different than I did, I'll try it..... It is a Speed Limit Cut Controller, I think is the same as BCC
