Methanol Fuel Injection Computer

The MFI system was designed from the ground up to provide a very simple and easy to understand tuning interface specifically for race only applications requiring very high fuel flow rates.  Other EFI systems offer many engine tuning parameters that are not always necessary for these type of applications.  The MFI uses an accurate algorithm to determine the correct amount of fuel flow based on a minimal number of engine sensors.

The MFI software provides a very easy to understand engine tuning interface.  Tuning is centered around one fuel map which can display AFR, actual fuel flow (lbh), or percentage of total fuel system capacity.  This allows users to adjust fuel flow in terms they are most comfortable with.  Tuning tools such as real-time data and data log tracking assist in adjusting fuel delivery values.
