Thanks Peter, like you said Terry cannot tell me much as they don't have this car model in US. I know other tuners like TMC etc have it for 520i but seems like everyone in this forum uses JB. Secondly, JB connects to 4 sensors where they rest only connect to 2 or 3 sensors. It just seem the more sensors it connects the better, but I can be wrong.
