flash-tuning platform developed by ProTuning Freaks for compatible BMW F-Series vehicles equipped with the N20 or N26 engine.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      Supported vehicles include selected BMW 125i, 220i, 228i, 320i, 328i, 320i GT, 328i GT, 420i, 428i, 520i, 525Li, 528i, X3 and X4 models.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      The platform provides direct access to ECU flashing, ready-to-use OTS maps, high-speed datalogging, diagnostics, map management and real-time vehicle monitoring through the bootmod3 web interface or mobile application for iOS and Android.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      Once any required DME unlock has been completed, bootmod3 calibrates the factory engine control unit through the vehicle’s OBD port. Supported maps can be flashed in only a few minutes, allowing the vehicle to move between stock, Stage 1 and Stage 2 calibrations.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      One compatible bootmod3 OTS map is included with the licence. The correct calibration is selected based on the vehicle’s compression ratio, wastegate type, fuel used, installed performance hardware and intended use.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      Additional OTS maps and professional custom tuning are also available through the bootmod3 platform for upgraded turbochargers, ethanol blends, Race Gas, methanol injection and more advanced performance builds.\n    \u003c\/p\u003e\n\n    \u003cp\u003e\n      Whether your N20 or N26-powered BMW is a standard daily-driven vehicle or part of a modified performance build, bootmod3 provides one complete platform for tuning, diagnostics, datalogging, monitoring and future upgrades.\n    \u003c\/p\u003e\n\n    \u003ch6\u003eEstimated Performance Gains:\u003c\/h6\u003e\n\n    \u003cdiv
