Programming a CTS-V Gauge Cluster into an ATS-V, out of pure spite

DEF CON 32 Creator Stage · Day 1 · Creator Stage
In a compelling presentation at DEF CON 32, software engineer and automotive enthusiast Varjitt Jeeva detailed his journey to retrofit a fully digital gauge cluster into his Cadillac ATS-V. Driven by what he described as "pure spite" against the exorbitant paywalls and proprietary services offered by aftermarket programmers, Jeeva embarked on a reverse-engineering quest to understand and replicate the process himself. His talk, "Programming a CTS-V Gauge Cluster into an ATS-V, out of pure spite," not only showcased a successful and cost-effective modification but also exposed significant vulnerabilities and design oversights within General Motors' (GM) diagnostic and programming ecosystem.
