In today's world, a mechanics most important tools are no longer found in their toolbox. Just think, in the 1980's Top Fuel dragsters made about 2500 hp using a 500 cubic inch ( 8.2 Liter) Aluminum Hemi headed engine, as amazing as this might sound, today this same displacement and very similar looking hemi headed engines are making over 10,000 hp! Why? It is a matter of optimizing all aspects of the engine to 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. Together TunerStudio 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.

Fuel Injection is as simple or complicated as the tools you use to work with it.
This sounds obvious, but is so often over looked when deciding what fuel injection controller to buy. It just doesn’t matter how good the fuel injection controller is if it has poor software for you to work with. Imagine you have the perfect after market fuel injection controller for your car, it has every option you ever see yourself needing, this Engine management System can control a 16 cylinder sequential injection engine with coil on plug ignition while managing a 6 speed automatic transmission. It does this with a monster 10GHz processor that can make every calculation perfect without even using a fraction of it’s resources. This is Great! BUT, think about it. It is only going to do what it is told to do by you as you set it up; And you can only do what you know by what you see the engine asking for.
The most important part of a fuel injection controller is you getting the information and being able to correct problems or take advantage of opportunities based on what YOUR engine is doing. Not reading about someone else’s engine, but getting the information directly from your engine, then having your engine information analyzed for problems, improvements and opportunities. This is just taking advantage of modern technology, yet it just doesn’t happen with the majority of fuel injection controllers available today at any price. You can spend $5000 on a fuel injection system and be left with unimaginably primitive software for you to see what it is doing or for you to correct it.
