AEM’s X-Series Wideband UEGO Air/Fuel Ratio Sensor Controller Gauges are built
upon unique, patented 100% Digital technology that makes them the fastest
responding wideband air/fuel ratio controllers in independent testing*.
The X-Series Wideband UEGO AFR Sensor Controller Gauge (PN 30-0300) measures 2
1/16th-inch (52mm) in diameter, and features a modern, visually striking
faceplate and new seven-segment center display that is 87% larger than the
30-4110 AEM Wideband Gauge’s center display. This creates the perception of a
larger overall gauge, but in a common 52mm size for easy mounting. 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 AEMnet (CANbus) output for data logging. AEMnet allows
additional X-Series Wideband Controllers to be daisy chained together (up to 16
cylinders) for recording AFR in multiple cylinders. It supports vehicle/system
voltages up to 16V, and can be used on EFI or carbureted applications, and
dynamometers in applications using gasoline, methanol, ethanol, Diesel, propane
and CNG.
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. AEM’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. AEM’s Wideband Controllers with X-Series
digital technology can reduce deadtime and improve the performance of your
vehicle through more accurate AFR tuning.
FACTORY CALIBRATION RESISTOR OR FREE-AIR CAL, IT’S YOUR CHOICE!
The X-Series Wideband Gauge and X-Series Inline Controller support the popular
Bosch 4.9LSU sensor and can utilize both the factory calibration resistor and
free-air calibration methods**. This allows users to take advantage of the
precise factory resistor calibration when a sensor is new but then allows for
free-air calibrations if the user desires when the sensor ages. It’s the perfect
marriage of simplicity and accuracy!
