When I was ready to start my freshly built engine for the first time using my Megasquirt II fuel injection system, I ran into some issues that I could not easily find answers for. One of the reasons for this was how incomplete and disorganized the information concerning the Megasquirt is. I hope that this post streamlines getting your engine started the first time with your new FI system, and not getting bogged down looking for answers to simple problems.
I have written this post for engines with a distributor since that is what I’m dealing with. Distributorless system can be a little more complicated to configure, but this is covered well in the megamanual. This post also assumes that you installed your Megasquirt yourself (so you know how everything is connected), you read as much as the manual as you can, you have everything installed and are pretty much ready to run and are using TunerStudio. I am obviously writing this for Megasquirt users, but this information probably applies to any E.F.I. system.
So let’s get started!
