DEF CON 32 - Programming a CTS-V Gauge Cluster into an ATS-V, out of pure spite - Varjitt Jeeva

Some cars are over-engineered, some are too basic, and some check every box except one. I did that research over months when trying to buy a new car, and landed on a 6MT Cadillac ATS-V while only wanting and dealing with Japanese cars, specifically Lexus/Toyota. The one thing it was missing was a digital gauge cluster, and programmers were asking $350, so I set off to figure it out myself. I then dove deep into GM electronics and programming, found a smart dude who initially cracked it all for free to spite all the money-grabbing gatekeepers, then became a hyprocrite, backtracking asking thousands to reveal his learnings. This presentation will go over how I programmed that cluster, posted everything on Github, out of spite.
