FAST XFI 2.050 Engine Management System

FAST XFI Engine Managements Systems are designed to provide the utmost in power and adjustability for serious racers. XFI 2.050 provides a host of upgrades including individual cylinder correction referenced to RPM. This feature allows for very fine tuning of an engine cylinder by cylinder throughout its entire RPM band. Dynamic Fuel Pressure Correction also allows for user-enabled correction for fuel pressure changes in real time. What's more, XFI 2.050 includes the added ability to interface with the cost-effective FAST EZ-LS Ignition Controller, while comprehensive, user programmable dwell settings for EZ-LS and XIM applications allow the user to finely tune the dwell time to match the ignition coils that are being used. Other spark features include increased resolution for power adder ramp retard, a timing offset table supporting alternative fuels by their Fuel Energy Constant and a high-RPM, spark-cut rev limiter.

XFI 2.050 provides a second communication port to allow for simultaneous use of the FAST XFI eDash and C-COM software, while new calibration parameters are designed to initiate a minimum oil pressure shutdown. In addition, a dedicated real-time baro sensor supports live corrections of barometric pressure for altitude changes. Finally, the progressive power adder fuel and nitrous solenoid duty cycles have been merged into one table to allow for more convenient tuning. Combine all of these features and the result is precision control and tuning capabilities never before thought possible.
