The Standard Edition is appropriate for the typical boat/off-road enthusiast. It has the ability to do real-time monitoring of all engine controller parameters as well as the ability to change a large set of the most common tuning parameters (fuel map, spark map, rev limit, etc). As an example, over 100 constants/scalars, over 200 flags/switches, and over 60 tables can be tuned in the MEFI-4B version alone with the standard edition.

The Professional Edition is appropriate for the shop user who needs access to a much more extensive set of tuning parameters. This level of complexity may be overwhelming to the enthusiast or beginning tuner, but is sometimes necessary for the more experienced or professional tuner. As an example, over 300 constants/scalars, over 300 flags/switches, and over 100 tables can be tuned in the MEFI-4B version alone with the professional edition. Users of the Professional Edition can also have their shop listed on our page of Professional Tuning Services.
