I recently invested into a Kess v2 and it arrives shortly, I've seen quite a few basic tutorials but none go into detail about custom remaps or where I can find premade remaps, I am looking to use it on my own 2 cars, a BMW 119D n47 2009, and a Golf mk7 1.4tsi DSG, what is the best way to go about learning to make custom remaps? And where can I find good premade remaps? :D

start with edc15 then transfer to edc16
