Welcome to the Rabbit ECU Project – a low-cost Arduino-Compatible DIY engine/project ECU

Here are some videos of the Rabbit DIY ECU running GDI, port and throttle-body injected engines:

Rabbit DIY ECU has open-source application code, open-source tuning and logging application, CAN bus or USB connection and the ability to run a modern PFI 4, 6 or 8 cylinder engine.

MDAC MAP-MATE Calibration Tool

Rabbit ECU comes with the powerful open-source MAP-MATE tool. Read more at the dedicated MAP-MATE page.

Rabbit ECU Arduino Due option (RA1)

The Arduino Due (SAM3X8E) is a plug-in option that provides a lot of functionality at a great price. Read more at the dedicated RA1 page.

Rabbit ECU Arduino Due option (RT1)

The Teensy 3.5 is a plug-in option that provides even more processing power and features. Read more at the dedicated RT1 page.
