    EFI Live Diesel Scan & Tune Tools

    EFILive has become one of the diesel tuning industry's most trusted scan-and-tune platforms, built around its FlashScan interface and AutoCal handheld tuner. The software and hardware combo is engineered specifically for GM Duramax and Ram Cummins trucks, giving serious tuners deep access to data logging, custom calibrations, and diagnostics most factory tools can't touch. CFM Diesel Performance carries EFI Live's tuning hardware for drivers who want full control over how their diesel runs.

    EFI Live

    Why Diesel Owners Trust EFI Live

    EFILive has built its reputation as a scan-and-tune specialist for GM and Dodge diesel platforms, developing the FlashScan and AutoCal hardware that professional tuners and serious enthusiasts rely on for deep calibration access rather than a simple canned power level.

    Its toolset covers real-time data logging, custom tune file loading, and full diagnostic scanning through the FlashScan V3 interface and AutoCal handheld, giving GM Duramax and Ram Cummins owners the same access professional tuning shops use to build custom calibrations.

    CFM Diesel Performance stocks a growing selection of EFI Live tools for GM Duramax and Ram Cummins trucks — FlashScan devices and AutoCal tuners below. Need help matching the right EFI Live setup to your truck? Contact our team and we'll help you get dialed in.
