Hello World!

I´m just getting started into the World of Chiptuning.
I´m graded at an automotive engineering school ind Austria, so at least i know some of the basics.

My Car is an BMW E90 320D ED with 119,8 kW. Because it´s an quite old car already, I decided to use it as my first experimental car for optimizing the software.
I´m planning to use the Kess V2 and WinOLS, but I´m still not sure which one to buy. I´m not interested in those unstable China Clones, but I heard there are some cheap Master Versions on the market.
The Autotune Tool is also an option to me.
