This is, however, fully playing with fire. > If you want to *really* party, replace & emulate the stock MCU when in the shop, then have a hidden switch (or whatever control scheme you like) to flip it back to your configuration. Alter values for daily driving, reset to stock when being tested, reflash to alternates for driving once you leave and continue polluting harder or whatever youвЂ™re doing. Honestly, the easiest way is probably to MiTM the stock OBD-II port and alter readings as needed. This is appealing, but (without knowing much about CAN) youвЂ™d have to prevent the signals from the original computer from reaching the tester, but still have it drive the car. > Wire in another port somewhere else (say, in the engine compartment away from the exhaust system. The state emission tests often involve using the OBD-II port, so youвЂ™d need to work around that. Posted in car hacks, Microcontrollers, Tool Hacks Tagged CAN, emulator, ESP32, ESP32-WROOM-32, obd-ii, SN65HVD230 Post navigation But this project could still be useful for anyone who wants to learn more about OBD from the comfort of their couch.

Unless youвЂ™re developing an OBD-II reader, you probably donвЂ™t have much use for an OBD-II emulator. Compared to the nearly $300 USD list price of commercial offerings such as theВ Freematics OBD-II Emulator, building one of these ESP32 based emulators should only cost you around $20. But like so many other niche projects, the price is a bit hard to swallow for the home hacker. If youвЂ™re wondering if such products donвЂ™t already exist on the commercial market, they do. From there itвЂ™s just a matter of compiling and flashing the codeВ has made available in the GitHub repo.

YouвЂ™ll also need a 3.3V power supply, as well as a USB to serial adapter to do the initial programming on the ESP32. At the most basic level, an ESP32-WROOM-32 is connected up to aВ SN65HVD230 CAN transceiver chip. So what makes it tick? Surprisingly little, actually.

It allows you to create fictitious speed and engine RPM values for the OBD-II device or software under test to read, complete with a slick web interface to control the вЂњcarвЂќ. Like so many others this hack was born out of necessity, as a way to test an OBD-II project without having to sit out in the driveway all day.

recently wrote in to tell us of an interesting project which doesnвЂ™t read the OBD-II port in a vehicle, but actually emulates one. If you want to do anything more advanced than changing a tire, youвЂ™ll really want to have the gear to interface with the vehicleвЂ™s computer via the OBD-II port.Д«ut for some, even that isnвЂ™t enough. DIY repairs and maintenance on a modern car is still possible of course, but the home mechanicвЂ™s toolbox has needed to evolve with the times. But today, for better or for worse, the average automobile is a rolling computer that runs on gasoline and hope (if it even still has a gasoline engine, that is). It used to be that you could pop the hood and with nothing more than flat head screwdriver, some baling wire, and tongue held at the optimal angle, you could fix anything that ailed your car.
