MegaSquirt Kit ECU

If you are looking for the lowest cost, rock-solid, fully tunable EFI and Ignition control solutions available, you’ve found it! MegaSquirt DIY EFI Un-Assembled Kits are incredibly well documented, clearly labeled kits where every component is labeled with it’s component number (to let you know where to install it on the PCB), as well as meticulous orientation and installation instructions. Additionally the documentation is very thorough, and walks you step-by-step through assembling your ECU, and stops along the way after major sections of the build to allow you to test the circuits you’ve built individually.

Tens of thousands of people around the world have successfully built their own MegaSquirt ECU and many of them successfully compete in a huge variety of motorsports. It’s not too hard for you to build your own ECU if you’ve got a bit of patience and are excited about the project and what you’ll learn along the way. Ever ‘painted by numbers’ before? It’s truly that simple to follow the directions and build your own ECU, by numbers.
