From DIY Plug-n-Play setups to starting from scratch to build your own harness, and from factory EFI conversions to MegaSquirt to carb-to-EFI conversions.  These articles are being gathered from around the web to give examples of how people are implementing the MegaSquirt ECU on various vehicles.  Some contain very detailed technical information and wiring diagrams, some are more general in nature.  If you know of an article that should be featured here email me a link at [email protected].
