No Problem Bro. You can have them do the tuning or you can do it yourself.I also bought a wideband lambda for that. Cost me more than the ecu hahaha.
You can get the cable and download the software from Perfect Power or ask GT to do one for you la. Its a serial cable with 5 wiring only.
Blackie, Toby still doing SMT6 and I taught that a I was one of the last few units he tuned? Cheers : )
