MegaLogViewer

MegaLogViewer - Datalogs Simplified

mlv
 
Power, performance, optimal efficiency; the objectives of almost any tuner, the key to achieving these objectives is in the data produced by your engine. To achieve these objectives you must know what your engine is asking for or it will never run its best. Captured Data logs are where a modern EFI controlled engine asks. But capturing data is only the first step; you then need simple ways to understand what that data means, what your engine is asking for. Being able to easily select, navigate and compare data fields is critical, but there is more. You want to see the whole story, not just at log traces 1 by 1 in a limited way. To get the full picture you need to see how different fields are related and affect one another, how it all ties together. You need the right tools to work with your data. Suddenly that data becomes so much easier to see and understand, you can sort through vast amounts of data in simple comprehensible views, then act on it.
