Over the years automobile engines have become increasingly complex, and with this added complexity comes an increased reliance on intricate computer systems to run them. These control systems are typically the fruit of many hours of research and development, carefully protected by the auto makers who create them. Instead of relying on a closed system to power his car, a Finnish hacker that goes by the name [synkooppi] has decided to do away with his diesel engine’s ECU altogether and build one of his own with little more than an Arduino.
As you can see from his web site, [synkooppi] has created his DIY ECU using an Arduino Mega, which is capable of controlling diesel engines that employ a Bosch VP37 or other inline diesel pump. So far he has all of the basic workings in place, which allow him to run and control an Audi diesel motor.
While many details about his homebrew ECU are hard to come by, he does have a series of development videos posted on YouTube which should help satiate inquisitive minds. For those of you with a spare diesel motor laying around, [synkooppi] has made the first release of his code available to try out.
Stick around to see a video of the ECU in action.
