It plugs into the factory harness in place of the stock ECU — it is not a piggyback — and opens up the fuel and ignition maps the factory unit locks away. Tune from your phone over Wi-Fi with the aRacer X-Tune app, or go deeper on a PC with SpeedTuningX through the PRO-LINK adapter.\u003c\/p\u003e\u003cp\u003eEvery ECU starts with a \u003cstrong\u003eQuick Burn\u003c\/strong\u003e: it pulls the latest base calibration for your bike from aRacer’s database in about a minute, with free calibrations for the common bolt-ons (exhaust, intake, big-bore kits). Stock and lightly modified bikes run well on that alone. Add an AF2 or AF3 wideband module and the ECU can AutoTune and run closed-loop on your actual engine.\u003c\/p\u003e\u003ch3\u003eWhat it does\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFull replacement of the factory ECU; plug-in installation on the stock harness\u003c\/li\u003e\n\u003cli\u003eOpen fuel and ignition maps with rev-limit and start\/idle control\u003c\/li\u003e\n\u003cli\u003eWi-Fi tuning from the aRacer X-Tune app (iOS \/ Android) or SpeedTuningX on PC\u003c\/li\u003e\n\u003cli\u003eQuick Burn base calibrations and free bolt-on calibrations from the aRacer database\u003c\/li\u003e\n\u003cli\u003eAutoTune and wideband closed-loop with an AF2 \/ AF3 module\u003c\/li\u003e\n\u003cli\u003eReal-time engine monitoring in the app\u003c\/li\u003e\n\u003cli\u003eWorks with the R Button, DG2 gauge and Sport D display\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits the 2015–2018 Yamaha YZF-R3 and 2016–2019 MT-03.
