i heard from a fren,a young chap driving a hyundai bought a dozen packs of 'pills' that will make people dizzy after consumption.... i wonder who that is... hmm... he's kinda thin and tall.....
am i right to say the ecu can be accessed via a harness ?
if so, is there a computer program cheap/free and simple enough to use to access the ecu realtime info? can DIY?
