Bimmercode vs E-Sys - which should I learn?

i use both. bimmercode for quick stuff, e-sys for anything complex. they complement each other well

Bimmercode can do all of those things you listed. Its much easier than E-Sys. I coded my entire F30 with Bimmercode in about 30 minutes.

E-Sys is more powerful but the learning curve is steep. If you just want basic coding mods, Bimmercode is the way to go. If you want to do advanced stuff like module swaps or retrofits, learn E-Sys.
