'What else can you plug your agent into?': one AI developer got Claude to fix his 1994 Jeep Cherokee with the help of a $3 Arduino

Developer Muhammad Zulali used the AI model Claude combined with a $3 Arduino to diagnose and reprogram the on-board computer of his 1994 Jeep Cherokee, fixing emissions issues and passing California's test. Claude reverse engineered the vehicle's system, identified a fuel delivery quirk causing excess nitrogen, and applied a custom fix without traditional mechanic tools.
