You read ECU files, modify calibrations yourself (or have them modified by a calibration partner), and write them back. Full standalone control — no subscription to another tuner's account required.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSlave\u003c\/strong\u003e tool connects to a Master user's account. The Slave user reads the ECU and sends the file to the Master, who modifies it and sends it back. The Slave user cannot modify calibrations directly. Choose Master if you're a tuner or shop. Choose Slave if you work with an existing tuner who provides calibration files.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAutotuner Master hardware unit\u003c\/li\u003e\n\u003cli\u003eAll OBD, bench, and boot cables and accessories\u003c\/li\u003e\n\u003cli\u003eFree lifetime protocol updates — new vehicles added regularly\u003c\/li\u003e\n\u003cli\u003e5-year hardware warranty\u003c\/li\u003e\n\u003cli\u003eFree worldwide shipping from YPG Motorsport\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4,000+ ECU protocols\u003c\/strong\u003e — OBD, bench, and boot modes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree lifetime updates\u003c\/strong\u003e — new vehicle protocols added at no cost\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo annual subscription\u003c\/strong\u003e — one-time purchase, no recurring fees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTricore and Boot support\u003c\/strong\u003e — for ECUs that cannot be flashed via OBD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-year warranty\u003c\/strong\u003e — hardware covered by Autotuner\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSupported Platforms (Partial List)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMercedes-AMG:\u003c\/strong\u003e M133, M156, M157, M176, M177, M178, M256, M276, M278\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW M:\u003c\/strong\u003e S55, S58, S63, S68, B58, N54, N55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFerrari:\u003c\/strong\u003e F154 (488), F160 (812), F140 (LaFerrari)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLamborghini:\u003c\/strong\u003e V10 LP580\/LP610\/Performante\/EVO, V12 Aventador\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMcLaren:\u003c\/strong\u003e M838T (650S\/570S), M840T (720S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorsche:\u003c\/strong\u003e 9A2 (992 GT3), MA1 (Cayenne Turbo), various Bosch MED\/MG1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudi:\u003c\/strong\u003e RS3\/RS4\/RS5\/RS6\/RS7\/RSQ8 — EA855, EA839, EA825\u003c\/li\u003e\n\u003cli\u003ePlus: VAG Group, Toyota\/Lexus, Nissan\/Infiniti, JLR, and more\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSupport \u0026amp; Training\u003c\/h3\u003e\n\u003cp\u003eTechnical support is provided directly by Autotuner.
