● YUMINASHI X-SERIES WIDEBAND UEGO AFR/LAMBDA/O2 GAUGE KIT (FOR FUEL INJECTION & CARBURETOR ENGINES)
● As an engine tuner, and it doesn't matter if it's carburetor or fuel injection system, running the right air fuel ratio is key to get the most out of your engine, and to avoid engine damage.
● The problem is that if you have ever tuned a carburetor or EFI system you know how difficult and time-consuming it can be, and without an AFR gauge (Air Fuel Ratio gauge) you are literally guessing.
● Carburetor tuning is probably one of the most frustrating things in the world of mechanics, since nobody like pulling jets in and out, adjusting air screws and needle with no basis to go off of, and it doesn't have to be!...
● That's why YUMINASHI is introducing the wide band O2 sensor kit with X-Digital wideband technology to make sure the days are gone of pulling your spark plug and trying to read the color, which is never very accurate anyways...
● By installing the YUMINASHI X-SERIES WIDEBAND UEGO gauge you take the guesswork out of tuning by using an O2 sensor, and this makes tuning without a dyno perfectly possible, and it doesn't matter if you are installing another jetting combination in a carburetor, or other flow rate injectors with or without a remap in your fuel injection system, you can see exactly the result of your modification while you are driving on the road and adjusting it then based on the results.
● The X-Digital wideband technology in this set gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition.
The controller’s high speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.
● We like to set out AFR or air fuel ratio to 12.5-13.5 where 12.5:1 AFR (0.85 Lambda) will provide the best cooling capacity and torque, and if you are trying to get the best gas mileage possible then stay around the 14.7 mark (Lambda 1).
● SOME TECHNICAL DETAILS:
YUMINASHI's X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers*.
The 52mm (2-1/16”) YUMINASHI X-Series Universal Exhaust Gas Oxygen (UEGO) Gauge features a four digit central readout and sweeping 24-color-coded LED display, providing immediate reference to the engine air fuel ratio (or Lambda) inreal-time.
● X-DIGITAL TECHNOLOGY
X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition. The controller's high-speed digital implementation ensures no loss of signal fidelity and full transient response, making it able to identify the slightest fluctuations in AFR and output them in full value.
● WHY RESPONSE TIME MATTERS
Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. YUMINASHI's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases (transport delay) can affect deadtime, it is not the only source. Often, the sensing elements response to the gas is the largest contributor to deadtime when an engine is in high RPM under load.
When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto-tune.
Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. YUMINASHI's Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.
● CONCLUSION
This YUMINASHI gauge is ideal for all vehicles including carbureted applications and engine dynamometers. A 0-5V analog output is included and can be used with data loggers or aftermarket ECUs including the YUMINASHI Infinity Engine Management System (EMS).
In addition, an CAN bus and serial data stream are also available for logging or mixture control purposes.
The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 36532-G30-0300 & 36532-X30-0300) features a modern, visually striking large faceplate and new seven-segment center display, and its slim depth (less than one inch overall) and ultra slim cup depth of .200-inches dramatically increases its application base and potential mounting locations.
The X-Series Wideband UEGO AFR Gauge has a user configurable display via buttons on the gauge face that allow you to change AFR values for different fuels, Lambda or O2%, change the center display to three or four digits, perform a free-air calibration if desired as the sensor ages, and change the CAN message ID when linking multiple X-Series Inline Controllers or X-Series Controller Gauges. A black bezel and black dual-faced faceplate for air/fuel and Lambda are included, and an optional silver bezel with white dual-faced air/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the new gauge’s durability.
The gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an CANbus output for data logging and it supports vehicle/system voltages up to 16V, which can be used on EFI or carbureted applications, and dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane and CNG.
