BillinBama

I'm coming from Porsches and BMW 's where coding is pretty common, but I've yet to find any threads about coding MB's. Specifically I want to change the lane change feature from 3 blinks to 5, make the auto start default to off, and a fewvother similar things. I'm assuming (hoping?) this is possible with my C43 AMG too, can anyone offer help? I have a Launch x431 which I plan to hook up when I get time, but it's dangerous to start making changes without a guide.
