    The Speeduino has been great since day 1! Base tune makes a big difference and my little 1.6 actually pulls now. Customer service has been great and the guys at Speedy EFI have been helping me at every wall I hit.

    Megasquirt looks fancier but who cares when it’s under a floorboard. I have had both. Customer service/tech support is worth 50 stars. I will solely deal with speedy EFI for ANY fuel management on any vehicle from here on out.

    This is a company worthy of giving your hard earned dollars to.

    Solid construction of unit with tight pins and outstanding customer service.

    The ECU has been working great in my wife’s miata for over a year now. The power difference on that 1.6, especially down low, was immediately noticeable.

    More recently I had some questions about swapping a VVT motor into this same car and Chris was friendly, knowledgeable, and replied quickly.
