A low cost, DIY friendly Engine Management System (ECU) based on the Arduino framework

Speeduino

The Speeduino project is a flexible, fully featured Engine Management Systems (EMS aka ECU) based on the low cost and open source Arduino platform. It provides the hardware, firmware and software components that make up an engine management system, all provided under open licenses. With over 1000 installations, Speeduino has matured into a product that meets the needs of the hobbyist and enthusiast community without driving prices to the levels of traditional aftermarket ECUs.

Overview

This repositiory contains official and user contributed tune files that can then be downloaded through SpeedyLoader

How do I contribute a tune?

This library contains both official tunes as well as user contributed ones. If you'd like to contribute your tune, a Pull Request or Issue can be submitted against this repository to get it added.

Please note that all tunes submitted are released under the Creative Commons CC BY-NC 4.0 license.

As an issue

If you're not comfortable with creating a Pull Request, simply create a new Issue (https://github.com/speeduino/Tunes/issues) and attach your tune file. Make sure to add details about your tune such as the specific make/model, whether it is for a stock vehicle or what the modification details are, which firmwar the tune was created for etc.

As a Pull Request

When adding your tune, 2 main steps are needed:

1. Your tune file should be placed in the relevant manufacturer folder (Eg "Mazda", "BMW" etc). If the manufacturer for your tune does not exist already, you should create this folder
2. You will need to add an entry into the bottom of the index.json file with the details of your tune. A sample entry is below:

{
    "id": "3",
    "displayName": "Miata / MX5 96-97 PNP",
    "make": "Mazda",
    "firmware": 201909,
    "provider": "Speeduino",
    "type": "Stock",
    "board": "Miata NA8 PNP",
    "description": "Tune for use with the Speeduino PNP units on 1996-1997 NA8 Miata + MX5",
    "filename": "NA8%20PNP%20base%20tune.msq"
},

Field List:

• id: This should be the next number from the previous last entry in the file
• displayName: A brief description of the engine / car your tune is for. If it is a non-stock tune then a very brief description of the modifications should be added. Eg: Miata / MX5 96-97 PNP with Turbo
• make: The manufacturer of the car/engine the tune is for. Must match the folder name that the tune file has been placed in (case sensitive)
• firmware: The firmware version that the tune was created with
• provider: A username that will be shown in SpeedyLoader for who authored the tune
• type: Either Stock or Modified depending on whether the tune is for a stock engine setup or a modified one
• board: The hardware design that the tune was developed on (Eg v0.4, NA6 PNP etc)
• description: A longer description of the tune. If it is for a modified engine, please describe in detail the modifications you've made
• filename: The filename of the tune
