The V8.9 Yuminashi Standalone ECU / Datalogger is the new generation of programable ECU units for Honda FORZA300 / NSS300, fully programmable fuel and ignitiong map indexed by throttle position and RPM..
The FORZA300 PGM-FI system has built-in correction for changes in air temperature and barometric pressure.
The YUMINASHI standalone ECU allows the rider even more control over fuel delivery and ignition timing, to suit your specific needs.
Programming the PGM-FI requiring a laptop computer, where changes to the fuel and ignition timing settings are entered on the laptop and then downloaded to the PGM-FI controller by serial USB interface.
**USB interface programmer cable is optional...
The Yuminashi tuning software is able to log AFR ratio's from a narrow band and a wide-band AFR meter, to make accurate datalogging from a optional installed wide band O2 sensor possible.
This allows you to see exactly next to each tuning value in the map how much the AFR ratio is from this particular spot on your tuning map. 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.
● Please open this PDF file and use it as a guide to gain both, maximum performance and maximum protection against engine knock (very important).
We strongly would like to suggest to use the wide-band feature from the new ECU with installing a BOSCH 4.6 or 4.9 wide-band O2 sensor and a bung to be welded on the exhaust where you simply can connect the white wire from the BOSCH O2 sensor to the green wire from your new Yuminashi stand-alone ECU / AFR datalogger. The red wire from your BOSCH O2 need to be connected to the 12V current after the contact switch, the black wire from the BOSCH O2 sensor go's to the ground from your battery or frame.
Like this you can right click and select the wide band sensor option in your tuning software and you're ready to start AFR datalogging...
**Please notice that you need to order the optional USB Programmer Cable if you don't have one yet (the one from our formal stand-alone ECU generation can be used).
