    We do not own Speeduino, we make ECUs to run the Speeduino firmware to help users who wish to get involved with Speeduino who may not wish to build their own ecu.

    Speeduino is a standalone open source ECU project aimed at the DIY type person who would usually install and tune it themselves, giving an extremely cost effective way to run their engine.


    Please keep in mind that being an open source project you will need some diy skills to use it.  If you are looking for a polished product, to have professionally installed and tuned, with strong dedicated support, you may wish to consider other options.
