Vortech Standard 6:1 FMU Recalibration Kit 6Z170-010
6:1 FMU Recalibration Kit for Vortech Standard Fuel Management Units
The Vortech Standard 6:1 FMU Recalibration Kit (PN 6Z170-010) is designed to change the rate of fuel pressure gain in an existing Vortech Standard Fuel Management Unit (FMU). This kit allows tuners and builders to recalibrate their current FMU to a 6:1 rise rate, making it ideal for higher-output EFI supercharger applications using larger-than-stock fuel injectors.
Rather than replacing the entire FMU assembly, this recalibration kit provides a cost-effective and precise way to tailor fuel pressure behavior to match injector size, boost level, and overall engine combination.
What the 6:1 Calibration Is Used For
The 6:1 FMU calibration is intended for Vortech supercharged EFI applications where larger fuel injectors are installed and excessive fuel pressure rise must be avoided. This lower gain rate delivers controlled enrichment under boost while maintaining stable fuel system operation.
Vortech specifically notes that the 6:1 calibration is commonly used on Mustang applications equipped with 30 lb/hr or 36 lb/hr injectors, making it a popular choice for upgraded street and street/strip combinations.
