MegaTunix is a tuning application for the
MegaSquirt EFI (Electronic Fuel Injection)
ECU, a semi-open design hardware fuel injection controller usable on just about any internal combustion engine. It supports most recent MegaSquirt firmwares for the MS-1, MS-2, and MS-2 Extra series. Also included is support for the JimStim ECU debugging tool and the 3rd party Performance Injection System (PIS) firmware retrofit for GM ALDL ECUs. MegaTunix includes an intelligent ECU interrogator, very flexible data logging, and a configurable and extendable GUI.
