aRacer RC Mini X ECU – Honda ADV 150 2019+

Full programmable engine management for the ADV 150 scooter — fuel, ignition and rev limit for exhaust, intake and big-bore builds.

The aRacer RC Mini X is a full-replacement programmable ECU for small-displacement EFI singles. 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.

Every ECU starts with a Quick Burn: 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.

What it does

• Full replacement of the factory ECU; plug-in installation on the stock harness
• Open fuel and ignition maps with rev-limit and start/idle control
• Wi-Fi tuning from the aRacer X-Tune app (iOS / Android) or SpeedTuningX on PC
• Quick Burn base calibrations and free bolt-on calibrations from the aRacer database
• AutoTune and wideband closed-loop with an AF2 / AF3 module
• Real-time engine monitoring in the app
• Works with the R Button, DG2 gauge and Sport D display

Fitment

Fits the 2019-and-later Honda ADV 150. Confirm model year, market version and keyless / non-keyless version before ordering. The ECU connector and calibration are specific to the model and year, so send us your year and VIN if you are unsure.

Setup and tuning

Plug the ECU into the factory harness, connect to it over Wi-Fi with the free aRacer X-Tune app and run Quick Burn to load the base calibration for your bike and mods. For full map access on a PC you need SpeedTuningX and the PRO-LINK USB adapter (sold separately). Heavily modified engines should be finished on a dyno by a tuner; aRacer’s U.S. team can also remote-tune from logs.
