AEM X-SERIES WIDEBAND W/ OBD CANAEM's X Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30 0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The 30 0334 X Series OBDII Wideband Gauge is validated to work with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashDaq software. The
AEM's X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge (PN 30-0334) provides tuners who are using piggyback tuning modules or open source software with the ability to view AFR through the factory CAN-bus stream that is output by the factory ECU, and deliver the most accurate, safe and powerful tune. The 30-0334 X-Series OBDII Wideband Gauge is validated to work with DiabloSport in Tune 3, Trinity 2, EFILive, HPTuners and DashDaq software.The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to a data logger. This OBDII pass-through capability replaces the traditional AEMnet stream available in the 30-0300 X-Series Wideband AFR Gauge Controller.
OBDII CAN-bus OUTPUT The OBDII output simulates an auxiliary ECU signal when plugged into a vehicle's OBD port, which requires a unique address from the other ECUs already on a vehicle's network. AEM's default OBDII CAN address will work with most popular vehicles and adjustments should not be necessary. However, AEM has provided OBDII address programmability through the buttons on the gauge face if a different address other than the default address is required, allowing users to program ECU #, Parameter Identification (PID), Message Identifier, and Bit Rate.
PATENTED X-DIGITAL TECHNOLOGY - It's The Fastest X-Series Widebands are the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.* The controller's high speed, patented, X-Digital technology (Patent 9,575,030) 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 reduce deadtime and can improve the performance of your vehicle through more accurate AFR tuning.

1/2” yoga mat. Great quality for the money.
Color: Aqua
I bought this yoga mat primarily for the 1/2” padding. I like the color and appearance with the ribbing on one side. I’m an older person and it’s difficult and painful to get down on my knees. This mat is comfortable and so easy to use. Doing my stretches and yoga are so much easier for me.

Great Mat, Slight Grip Issue (lika all mats)
Color: Black
Comfortable and solid for workouts, but it can be a bit slippery on the floor during intense poses. Still a great overall yoga mat.

The tear-iest anti-tear mat
Color: Green
The good: It's super thick and squishy. So it has that nice bouncy feeling when you're using it. The strap is easy to secure on the mat as well once it's rolled up. The color is also super cute.
The bad: it's not Anti-Tear. It says in the name that it is, but the second I got it it tore. Only a little bit but still. For how cheap it is, I don't mind, but keep that in mind if you're buying this.

Love
Color: Deep Wine
This is a great quality, thick and pretty colored yoga mat! It's easy to roll up and put away and of course, just as easy to sanitize than the yoga mats with the little dips and crevices in their designs.

Thick & sturdy.
Color: Blue
Great mat! Nice thick, sturdy foam! -- Im using it along my raised garden beds so I can crawl across the area that's covered w wood chips to work. I cover up lumber edges w old staples with one edge too, and can push myself up & slide it along beneath me. Great on my knees and elbows. Eliminates the need to constantly get up & down. Nice thick, sturdy foam! Gets slippery fast if I hit it w the hose!
