Confused by all the options out there? Start here to determine which Engine Control Unit fits your needs.

MegaSquirt EFI has grown from the original solder your own kits into a line with ECUs to fit a wide variety of needs and budgets. We now have everything from affordable solder your own circuit board kits to plug and play systems you can install in under an hour for popular applications.

You could break these systems down into three main categories:

  1. Max Affordability DIY EFI Kits you build yourself.
  2. Fully Assembled Wire-In Standalone ECUs at an incredible price point.
  3. AMP EFI, a high performance engine & powertrain control systems brand focused on high I/O, high horsepower drag and road racing solutions based on the flagship MS3Pro & MS3Pro Plug & Play models.

Read about the different types of systems we have so you’ll know which MegaSquirt Engine Management System is right for you!

At first glance, what do you think interests you most?

1. Low Cost /  Extremely Affordable DIY EFI Systems — Budget Racers / Hobbyists / Hardcore DIYers

Would you prefer to spend less money and not mind putting in a bit more work? Do you enjoy the satisfaction of working on your own car? If you love the pride that comes from knowing you built everything on the car, you can even get a kit to build your own Engine Control Unit from a circuit board and bags of parts!  These DIY EFI kits continue to be extremely good sellers and customers have some incredible results running these systems they built themselves! We also offer the MegaSquirt 2 and 3 assembled and ready to wire up.

These approaches all share a common thread – they’ll take a bit of research to determine what you need and will require you to know your engine and ignition system well (or learn it, which isn’t a bad thing), so they’ll be a bit of a learning experience.  Without a doubt though, when you put that effort into your system your results will be incredible and at the same time less expensive than pretty much any other engine management system option available.

Alternatively we can set up an ECU to meet your specific needs and ship you a ready to wire in and run EFI Solution.  That takes us on to the next category Fully Assembled Wire-In Standalone ECUs


2. Fully Assembled Wire-In Standalone ECUsWant to get right to the installation!  This is for you.

We offer a number of ready to wire-in Engine Management Systems that in many cases will work for you right out of the box. If you do you need a feature that’s not available off the shelf, it’s easy to work with our sales department to special order an Engine Control Unit with these specific modifications already installed and ready to wire up!


3. Pro Systems including MS3Pro and MegaSquirtPNP Gen2 Plug and Play EMSwhen ease of use and maximum performance is the only thing that will do…

When your time is money (or you just plain don’t have any time to spare), sometimes it’s worth paying a bit extra to make the installation go as smoothly as it possibly can. Maybe you don’t want to go through a list of options and specify what you want included with your ECU like you were ordering a pizza, and you definitely don’t want to have to open the case and solder anything in yourself!  You want something you can just take out of the box and have it work. This might take the form of a universal wire in ECU that’s got all the inputs and outputs it needs to run a wide variety of applications when you wire it up, or it could be a plug and play system that plugs right in place of the existing ECU and is ready for you to start tuning your engine.  Either way, we’ve got you covered!
