**Since August 2016, Yuminashi has introduced a new high performance ignition coil for the MSX which you can find over here. This ignition coil will give you the spark energy you need to completely burn the extra fuel that you will be adding with this stand-alone ECU, or even with only a bigger injector upgrade on a stock ECU. We highly recommend you using that ignition coil alongside this stand-alone ECU even if you are an expert in the field of fuel injection tuning.
● The 2017 38770-K26-003 Bluetooth V6.1 Yuminashi Stand-alone ECU / Datalogger is much more as just a replacement for the formal 2016 V8.9 generation.
First of all is the new 2017 V9.1 series compatible on both, the MSX125/GROM125 and the MSX125SF/GROM125SF.
The huge jump forward is in the fact that the new 2017 V6.1 has a Bluetooth connection, and this means that your wide band O2 gauge can read wide band AFR data while you are driving on your Android system!!
This means that you can see the AFR ratio in each and every field, and are able to adjust these fields on the fly with your Android system.
This eliminate basically the need for a dyno since you are able to make all correction while you are driving based on a real life situation/real life load like uphill driving, or driving against a headwind, etc...
While the software can run with the stock narrow band O2 sensor, we strongly suggest not to do so because it's a total waste of time and money if you are doing so.
The stock 1 volt narrow band sensor isn't able to read accurate AFR reading, so the results you will see on your screen will be far away from accurate/reality with possibly serious engine damage as result!...
If you don't have a wide band O2 gauge yet, then we like to recommend the Innovate MTX-L gauge (please click the link in yellow, not supplied by our company) because this California based company has a basic no nonsense device which can take a lot of vibrations and is perfect to do the job compared to others we tried.
It's also very easy to connect this gauge to our standalone ECU where you only need to connect the yellow wire from the MTX-L gauge to the green wire from our standalone ECU, and after a right click on the AFR meter from the program where you need to select "wideband" then you can see exactly next to each value in the map how much the AFR ratio is from any particular spot in the map and like this it becomes really easy to know if you have to increase or decrease the percentage from that particular value in the map to get your optimal AFR target.
If you have set your perfect map, then keep in mind that your AFR ratio will change based on the temperature.
With the 2016 IAT enabled version we had made it possible to increase or decrease your entire map based on the Intake Air Temperature (IAT) which works based on the build in IAT sensor from your bike, with the 2017 V6.1 version we have kept this to make your tune possible around the year.
If it's starting to get colder or warmer compared to the temperature when you had set up your map, then go to the program (you need to use the USB tuner Cable for that, software is free), go to "enrichment correction" and enter a value based on the actual temperature to get your entire map back like it was when you had set up the map.
Like this you are able to correct and set up your standalone ECU to run your tune day in, day out.
● Please open this PDF file and use it as a guide to gain both, maximum performance and maximum protection against engine knock (very important).
You need to order the optional USB Programmer Cable if you don't have one yet (the one from the formal stand-alone ECU generations can still be used), because you will need this cable to make the ECU work based on your local environment conditions!
If you haven't one yet, then please don't think that you won't need it, you can order it over here...
