The wireless M-Tuner v3 dongle plugs into the OBD port and a Windows laptop does the flashing, so the ECU never leaves the car. Off-the-shelf maps cover 91, 93 and 100 octane, and On-The-Fly Live Map Switching lets you change between them while you drive.\u003c\/p\u003e\n\u003cp\u003eM-Engineering's custom code adds Detonation Defense: when knock events go beyond a set threshold, the car is put into map slot 5 within 20 milliseconds for about 10 seconds. The PSE valve modification for the GT2 RS, which forces the PSE exhaust valves fully open, is enabled, and Auto Start\/Stop is disabled on all off-the-shelf maps. The software also reads and clears engine faults, datalogs, shows live data and flashes back to stock whenever you want.\u003c\/p\u003e\n\u003cp\u003eStage 2 is generally about 20 to 40 whp more than Stage 1, according to M-Engineering, and Stage 3 cars with upgraded intercoolers run the Stage 2 calibrations. Upgraded turbos are not covered by the off-the-shelf maps and require a ProTune. New factory spark plugs gapped to .022 are recommended but not required.\u003c\/p\u003e\n\u003cp\u003eM-Engineering also supports the track-only Clubsport, EVO-MR and 935 derivatives on 100 octane only; ProTuning is available for upgraded turbos, built motors and ethanol blends.\u003c\/p\u003e\n\u003ch3\u003eKey specs\u003c\/h3\u003e\u003ctable style=\"border-collapse:collapse;width:100%;margin:12px 0\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"background:#03589c;color:#ffffff;padding:8px;text-align:left;border:1px solid #03589c;width:32%\"\u003eInstall method\u003c\/th\u003e\n\u003ctd style=\"background:#e8f4f8;padding:8px;border:1px solid #c9dfe8\"\u003eAt-home OBD-II flashing with the included M-Tuner v3 wireless dongle.
