• MegaLogViewer-an application to view and graph MegaSquirt Log files. It will graph any field in your MegaSquirt(1, 2, 3, MSnS-Extra…) log file captured by TunerStudio, MegaTunix or Palm based MS-Logger. Written in Java to support all OS’s and platforms.
  • You’ve simply got to use MegaLogViewer…. The log viewer is just the beginning, with the log based tuning capabilities (reference your current map and datalogs on the same screen and make tweaks as needed), and the VE Analyzer, there is a lot of power here!
  • After MegaLogViewer changes your life ;)– and even though it’s free and you’re not obligated, please consider registering MegaLogViewer to thank Phil Tobin for his development effort, he’s done this out of his own goodwill and I for one would like to see more cool tools like this!
