MS3 Firmware Manuals

As TunerStudio and Megatune use the same ECU Definition ("ini") files for MS1 & MS2, the Navigation and dialog layouts are the same and the same manuals are valid for TunerStudio. Some older firmwares have references to MegaTune configuration, disregard these sections, but the settings for the firmware will be the same.
