BigStuff3 just got Simpler and more Powerful than ever!

When it comes to modern horsepower, the most important tools are no longer found in your toolbox. Just think, in the 1980's Top Fuel dragsters made about 2500 hp using a 500 cubic inch Aluminum Hemi headed engine on Nitromethane, today there are drag and drive cars that crush these numbers! No Nitromethane and they can drive thousand(s) of miles between refreshes. Why? One big reason is a matter of optimizing all aspects of the engine and improving efficiency. This demands the tools to gather data to understand what is happening inside the engine at the completely and identify opportunities to improve efficiency. EFI has brought new capabilities to enable maximum efficiency, but also additional complexity getting started. Together BigComm Pro and MegaLogViewer bring you the power to capture, view and analyze vehicle data as your engine produces it, then act upon it. These easy to use applications simplify making changes and even offer recommendations and automatic correction using data analytics at a level that is not offered by any other automotive tuning solutions.
