I've always been fast with learning some of these concepts with computers although i have a few questions and ideas. Why do we need an expensive "Tech II" device for tuning and diagnosing issues with cars. My 2005 Corvette uses its old ecm module and needs this big overpriced tech II device for tuning and diagnostics and my phone and gaming pc are so capable... cant we just bluetooth adapter link to the obdII and run/ emulate the same programs? The supposed "uncrackable" remote tuners should be usable too if the values are downloaded. just a thought thank you
