If you’re wondering why the ECU connector has four positions, and the stock ECU has only three – the connector Mazda used comes in two, three, and four position versions of the same connector. It’s easier for us to use the four position version, and you simply do not use one of the four connectors, rather than DIYAutoTune maintaining an inventory of all three variations on this connector. Don’t worry, this ECU does still fit cars with an ECU with just three plugs.

Note: Although there is a paid upgrade to TunerStudio, it is not needed to tune this ECU. The free version included on the USB Stick can access all the features and tables of the MegaSquirtPNP. The paid version of TunerStudio simply adds tuning and analysis software, such as VE Analyzer Live to tune the fuel tables based on wideband O2 feedback (requiring a wideband O2 sensor and controller, sold separately).
