A 1994 Jeep Cherokee's engine computer read through a $3 Arduino
With no OBD2 port or working scan tool, the owner wired a cheap Arduino to the engine computer and had Claude Code and Codex read it live, log drives, copy its program and run their own code inside it.

The full story
A 1994 Jeep Cherokee has no OBD2 port and no scan tool that works with it, so its owner wired a $3 Arduino Nano to the engine computer and had Claude Code and Codex work it out. Over about a week they read the computer live, logged drives, copied its entire program and ran their own code inside it, with Claude working out the wiring and running the fuel pump, as the owner chased a failing smog test. The wiring, code and agent instructions are on GitHub for other 1991–95 Jeep and Chrysler owners; parameter tables came from László Dániel's ChryslerScanner.
