MegaTunix for those who were unaware of it

[djandruczyk]

Megatunix is a native tuning software for MS-I/II hardware, including hte MSns-Extra firmware series, including microsquirt.

It's available for Windows, Linux, OS-X and potentially bsd/solaris (if you have the needed pre-reqs)

Pros:
Free GPLv2!
Photo-realisitic Gauges/Dashboards
Supports almost all current FW versions
Unique custom designed Tabbed Gui Interface designed to be more intuitive.
Supports VEX files for table save/restore
Doesn't read/use the MT/TS ini files
Datalogger, and rudimentary playback tool.
Includes additional tools for firmware loading (msloader/mtxloader), Gauge design (gaugedesigner) and Dashboard Layout design (dashdesigner).
Adaptive Gui interface.

Cons:
Does NOT support MSQ files (not likely to)
Doesn't read/use any of the MT/TS ini files
Doesn't yet have Auto-Tune (planned for future release)
