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. Auto Start\/Stop is disabled on all off-the-shelf maps, and ProTuning is available for upgraded turbos, built motors and ethanol blends. 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\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.
