I've had the same thing sitting on my bench for months now, and haven't had the time to fit it. They sent me a steel collar. Didn't realise I had to request a stainless one. So I've got to make one.By the way I have fitted the Innovate LC-1 and G2 gauge,it is showing my fuel very rich on light throttle as I thought it may have been.I intend to eventually datalog and try and improove the running,but I need to find a cheap laptop first ! If you are fitting one give me a shout and i will explain my install.
