Car owner says they just did a bit of wiring and driving, crediting Claude and Codex with the rest of the job.

Watch On The above video documents Muhammad Zulali’s journey from the Jeep failing consecutive smog tests, to managing to hook it up and get readings from the ECU, to tuning and fixing the engine emission issues. All the while, Claude provided guidance, and Codex wrote any required code.
This rather old Jeep was failing the California smog tests due to producing too much NOx at certain test speeds. It initially failed at 25mph. Then, after Zulali made some adjustments to the oxygen mix, it failed at both 25mph and 50mph. Yes, it got worse.
Zulali admits he was effectively making adjustments blind, and subsequent regulatory pollution tests cost nearly $100 each time. That’s clearly a big problem, but we have AI to help us in 2026. Actually, it was AI and a $3 microcontroller, contributing to a total bill of materials of no more than $15.
The first hurdle facing the possible AI solution was the question of how to interface an old car and a new laptop. Claude told the Jeep owner that the engine communicated on a Chrysler SCI bus at ~7,800 baud, which was electrically inverted compared to a typical serial port. An Arduino Nano can handle the required inversion and hook up the data to a modern computer. The Nano was breadboarded , with a few necessary wires, three of which connected to the 6-pin diagnostic plug in the Cherokee.
