What is this?

epicEFI is a fork of the open source electronic fuel injection firmware ruseEFI. The firmware was forked to enable more agile software development and to introduce more features than the mainline firmware offers.

Obtaining the firmware

To download the firmware, you must first know what hardware you have and its respective internal name.

If you are not sure what hardware you have, navigate over to the list of supported ECUs and verify what ECU you have and its internal name. The specific internal name and physical hardware are not always 100% clear and you need to select the hardware you actually have.

If you have a epicECU, the internal name is epicECU.
