MegaSquirt is available several iterations from dedicated companies, boutique sites, individuals who will build them in their spare time, to DIY kits. As of 2018, the most popular pre-built MS kits used by members are:

  •, selling DIY kits, and a myriad of Plug-and-Play, Miata-specific kits as well.
  • MSLabs, also known as "Reverant"-built MegaSquirts.

Purchasing Considerations

As with all ECUs, consider the following before making your purchase:

  • After purchase support from the vendor.
  • If the vendor is unavailable, size of online community for support.
  • Anticipated support from a dedicated business vs boutiques or individuals.
  • All MegaSquirts are not the same. Some will come with dedicated basemaps and features, others with a generic map that requires a lot of work, or have features to build and learn your first map. Dedicated companies may often have a strong, generic basemap, but a boutique seller may have a unique and custom map available to your needs - or not. Buyer beware.
