Works Good On Can Bus Vehicles
Works good to log my wideband on hptuners through obd port. Must have pro features enabled on hptuner device. Only works for can bus vehicles not serial data. Would Highly recommend. I use mine as a mobile unit

Very fast CAN based wideband
Awesome device. This model is designed to provide a CAN based output that can be then logged in HPTuners. It is extremely fast and when connected via the CAN bus (OBD port) ground offsets are a thing of the past. Install could not be easier. Install sensor, connect unit to a switched power source and then plug in the provided OBD "splice" to an OBD port. Connect HPTuners to the other side of the OBD "splice". The analog 0-5V output is also extremely fast and accurate on this model. The 0-5V output connectors are NOT pinned in this setup, though the pins can be purchased for a few pennies, so they are simple enough to add if need be. I can't think of any reason not to buy this wideband if you are in the market for one.

Great for tuning
Used this to tune my 2019 dodge charger RT and this is all you need, quality was great, you get the best bang for your buck. I highly recommend easy to hook up I recommend hooking it up to your battery, easy to install easy to put away.

Item is for Canbus equipped vehicles. 2013 and newer.
Don't make the same mistake I did. This item is for newer vehicles with Canbus. If your vehicle is older than 2013 it probably wont work unless you cut the end off it and switch the pins around. Works well though.

Great company
Nicely packaged and worked as it is supposed to. This co is promp with shipping also. I’ve done several transactions with 269 motorsports and have no complaints.

Best AFR gauge available
I purchase this so I can tune my car with HP Tuners. This allows me to do a pass thru to the tuner and still get my gauge results. Easy to install. Works perfect. BTW, don't go to a tuner shop to get the o2 sensor installed. I shopped all over town to get the welded in and I had price ranges from $75-$250. Went to a muffler shop and they did it for $15 in about 10 minutes.

Future of widebands!
The future of wideband sensors. The installation was super easy, and HPTuners immediately detected the wideband when I added the WB EQ channel. The sensor is capable of a 100hz polling frequency for very fast updating. HPTuners reads much faster than the gauge itself. For any modern tuner using software such as HPTuners, this is what you need. No worries about ground offsets or wiring serial inputs. Just plug your laptop into the OBD2 port's pass-through adapter and start logging.

Overpriced junk
Absolute junk with terrible customer service from AEM. Was installed on my vehicle and kept in my garage. Has about 3k miles on it MAX. The gauge failed on the top of the second digit and AEM won't do anything to help me out since I'm a few months past the warrant period. Wont even sell me just the gauge, I have to buy the WHOLE KIT AGAIN. Terrible product with terrible customer service from AEM. The fact that they can't even sell me just the gauge is ridiculous.
