Taking tuning for the eSP engines to the next great leap, introducing the YUMINASHI STANDALONE ECU FOR PCX 125 LED/PCX 150 LED.
At YUMINASHI, we understand that a fully standalone for the PCX engines are not technically possible because unlike other bikes, the Engine Control Module (ECM) for these engines contain also the starter function as well as battery recharge. This problem has prevented the emergence of a stable, truly open source standalone ECU for the PCX engines for years. However, as typical as it is for us, we have solved this problem out with a special wire loom in order to let you connect a true standalone ECU to your stock wire harness. Please be noted that your stock ECM would still need to be installed in order to start the bike and recharge the battery. The rest, however, is fully controlled by you, the tuners through our standalone software.
Since this is a standalone ECU, you the tuners have full control over almost everything. Injection control, both the amount and the timing of the injection event as well as ignition timing, and enrichment circuits to compensate for cold engine start are all available to tuners who want to take advantage of them and allow for a much more precise tuning experience which will undoubtedly lead to a better running engine and higher performance.
You will need to buy a wideband O2 sensor as well as this data link cable (if you want to physically connect the ECU to your laptop or PC) or to bring your scooter to a dynamometer service which can perform air fuel ratio tuning in order to take the most advantage of this standalone ECU unit. This unit comes with Bluetooth enabled, so if you have an Android phone, you can use Bluetooth to tune the setting yourself.
