Owner uses AI and Arduino to help 1994 Jeep Cherokee pass smog test
An AI enthusiast successfully modified an old 1994 Jeep Cherokee using Claude, Codex, and a cheap microcontroller to pass strict California smog tests.
Car owner Muhammad Zulali repeatedly failed California smog inspections because his vintage Jeep Cherokee produced excessive NOx emissions. Facing costly diagnostic fees, he used an Arduino Nano board and a laptop to connect with the vehicle's primitive engine computer. With Claude providing step-by-step guidance and Codex writing the necessary programming, Zulali managed to log engine fault codes and diagnose the emissions issues. Because the car's original computer lacked reflashable firmware, Codex injected custom code directly into a nearby EEPROM, ultimately solving the problem.
