Description
 
Fast, quick, easy electronic fuel injection fuel management. That’s what is in the package of every MPS Fast FI Mixture Control. The original “MPS Mixture Control” sold in 1981 was the first motorcycle fuel injection aftermarket product. The second generation Fast FI Mixture Control sets new standards for fuel management with a dry nitrous system incorporating the instant rich feature. The Fast FI Mixture Control was designed to be a universal application and will work on most late model four cylinder electronic fuel injected motorcycles.
The MPS Fast FI Mixture Control P/N 1-0337 is a simple means to adjust the fuel curves on your fuel-injected motorcycle. This allows for tuning after the installation of aftermarket exhausts, intake modifications, or internal motor modifications. It can only richen the fuel mixture. It cannot lean the mixture. The Fast FI Mixture Control has a low speed pot that adds fuel at low speed much like a mixture screw on a carburetor. The accelerator pump pot is an extra enrichment when the unit senses rapid rpm acceleration.  This acts like the traditional accelerator pump on a carburetor. The high-speed pot controls the high RPM like the main jet of a carburetor. The high-speed RPM set pot determines what RPM the low speed pot is no longer controlling the mixture and the high-speed pot takes over. The Fast FI Mixture Control has an instant rich feature to work with Dry Nitrous Systems. It locks the fuel injection system in a full rich mode instantly via a signal from the Dry Nitrous System. This means no more reprogramming for NOS operation. The Fast FI Mixture Control looks at the fuel injection map the same way the factory does and adjusts it the same way the factory does. Because our product is not compatible with other aftermarket products we recommend removing any other type of non-factory adjustments, downloads, etc. before installing the Fast FI Mixture Control.
