Compared to the nearly $300 USD list price of commercial offerings such as the 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 you’re wondering if such products don’t already exist on the commercial market, they do. From there it’s just a matter of compiling and flashing the code has made available in the GitHub repo.

You’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 a 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 “car”. 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 doesn’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, you’ll really want to have the gear to interface with the vehicle’s computer via the OBD-II port.īut for some, even that isn’t enough. DIY repairs and maintenance on a modern car is still possible of course, but the home mechanic’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.
While this feature might require some additional lighting on the gauge cluster for Suzuki to be able to offer this feature, we have seen other “missing” features in devices that could be unlocked with a laughably small amount of effort.Ĭontinue reading “Adding Upgrades To A Stock Motorcycle” → Posted in Transportation Hacks Tagged arduino, cluster, gauge, gear, indicator, motorcycle, OBD, obd-ii, Suzuki The build is very professionally done and is so well blended into the gauge cluster that even we had a hard time spotting it at first. By using an Arduino paired with an OBD reading tool (even motorcycles make use of OBD these days), was able to wire an LED ring into the gauge cluster to show the current gear while he’s riding. Even though all the hardware was available in the gearbox, and the ECU was able to know the current gear in use, there was no indicator on the gauge cluster. The main feature that was lacking on this bike was a gear indicator.
And, it seems as though Suzuki might be following this trend as well, as found out when he opened up his 2011 Vstrom motorcycle. Even if the hardware is the same across all the models, you can still be on the hook if you want to unlock anything extra. In today’s world of over-the-air firmware upgrades in everything from cars to phones to refrigerators, it’s common for manufacturers of various things to lock out features in software and force you to pay for the upgrades.
