Store description excerpt
GhostTune brings serious aftermarket EFI tuning, monitoring, and diagnostics to iPhone and iPad. Current compatibility: GhostTune v1 is verified for MicroSquirt® hardware running MS2/Extra 3.4.x firmware. Support for additional ECU platforms is planned for future releases. Built for enthusiasts, builders, and tuners who want a modern mobile interface in the garage, GhostTune connects to supported engine management systems through a compatible Wi-Fi ECU bridge. View live engine data, work with tuning tables and ECU settings, capture diagnostic information, and make controlled tuning changes without being tied to a laptop. BUILT FOR REAL EFI WORK • Monitor live ECU data and engine parameters • View and edit supported fuel, AFR, and ignition tables • Access detailed engine management settings and calibrations • Perform guided diagnostics and troubleshooting • Capture logs and diagnostic information • Use Ghost Guide for built-in explanations and contextual help • Work from either iPhone or iPad • Connect locally to supported ECUs through a compatible Wi-Fi bridge • Explore the interface without connected hardware using Demo Mode SAFETY-FIRST ECU EDITING GhostTune is designed around controlled ECU access. Write-capable functions use protected workflows, ECU verification, readback checks, recovery safeguards, and clear separation between temporary and permanent changes. Before live editing, GhostTune verifies compatible ECU communication and establishes a protected recovery baseline. Safety-sensitive functions remain gated when the required ECU state or communication cannot be verified. MADE FOR THE GARAGE Whether you’re checking live data beside the engine, reviewing a fuel table, diagnosing a sensor issue, or refining an EFI setup, GhostTune puts powerful engine-management tools in a mobile interface designed for hands-on tuning. Compatible ECU hardware and a supported local Wi-Fi bridge are required for live ECU operation. ECU compatibility and available functions vary by controller and firmware. GhostTune does not require an account or an internet connection for normal live ECU operation. Compatible ECU hardware and a supported Wi-Fi bridge are required for live ECU operation. Available features vary by ECU and firmware version. Additional ECU platforms will be added only after their communication, tuning, and safety workflows have been validated. GhostBridge, Crux Resolve’s purpose-built Wi-Fi ECU bridge, is available separately at cruxresolve.com. Compatible third-party bridges may also be supported.
