MegaTunix is the only native tuning software for Unix (and now Win32) class operating systems that supports the majority of megasquirt firmwares. It has been redesigned in such a way as to be extensible to support new firmware variants with little to no new code needing to be written. The new design permits the gui tabs that relate to MegaSquirt variables to be redesigned using the Glade GUI designer for windows or Glade gui designer for Unix to change or alter the gui look/feel to accomodate new controls on more advanced firmwares.

This tuning software is capable of the most complete and accurate nterrogation of the ECU than any other tuning software out there currently (MegaTune, MS-Palm, MegaSquirtPCC and even TunerStudio). This advanced interrogation is configurable and provides the most complete detection of the target firmware, (such to prevent mis-detection) and would even allow MegaTunix to work with non-MS hardware though this left up as an exercise for the user.

MegaTunix is also a native application, i.e. not running under a VM like java, so it tends to be faster and more responsive.

MegaTunix is developed on Linux (Ubuntu and Gentoo Linux specifically), but does work on all other Linux distros (Assuming the proper libraries are installed), FreeBSD and Mac OS-X (with macports/ darwinports and the necessary support libraries installed) and Win32 platforms as well.
