Here is what may seem like a dumb question...(so plz bear with the DIY noob lol). On Eurocharged website the flash cable looks like a standard usb-obd2. From what I've read and was told that type of connection offers rather limited options for tuning. Instead one should use a 38-pin cable (see pic). The intel came from a couple of friends of mine on the BMW forum (running an M5 and a 740IL, both are DYI tuned via a similar 30-something-pin BMW cable with good results) so im wondering if that is true for our ecu's as well. If our ecu can be flashed via a regular obd2 then could we use say a ELM327 bluetooth module to get it working with Eurocharged software?
