#4775, "RE: What tuning program for MS?" In response to In response to 0
TunerStudioMS is the new de facto standard for tuning Megasquirt ECU's. MegaTune is great for MS-I, but TunerStudio also supports MS-I and has a more features. MegaTune is not capable of handling some of the features in the latest MS-II firmware versions (mainly the 3.x alpha code).
Most other tuning suites for Megasquirt are deprecated; such as MegaTunix, which was originally MegaTune's counterpart for Linux. TunerStudio uses the Java virtual machine, so it's cross-platform.
