Just ordered a K+DCAN Coder, What should i code?

I mostly ordered the adapter to code out a few light warnings from my car, aka brake sensor, TPS monitor, and blinker warning lights.



What other mods should i do? Im hearing something about alpina trans mod? and ideas? Warnings? thoughts?





ALSO this is what i ordered, a bit cheap is it going to work?
