Best option on the market- WORKS WITH DIABLO
When modifying your car to the point of needing a customer tune the AFR(air fuel ratio) is one of the most important readings you need. Not every car is equipped with wide band 02 sensors to do this correctly. In this day and age with email and remote tuning being so popular the piggy back OB2 connection is NICE. Plugging this unit into your obd2 and then plugging in your tuning/logging device allows the readings from this gauge to be captured just at is it was a factory PID. Works perfectly with HP tuners and DIablo. This is MUCH better than the old method that didnt work well.

Quality from AEM
Install is easy if you’re mechanically inclined, plenty of cable length. 10/10

AEM 30-0334 Wideband with Direct OBD and definitely buy it from HIGHEND AUTOSPORTA
Talk about Customer Service these guys went above and beyond what most companies do these days. Asked him about shipping and the model. He got back to me under 5 minute. Had it shipped out the SAME DAY EVEN !!! I received the Wideband a day earlier than expected. AEM makes great products. I custom make Gauge clusters for cars. This is for my personal car. So STOKED To get it installed.

A must for HP tuners
Pairs well with HP tuners. I used it with some diesel tuning and it worked great as well.

Cheep generic O2 sensor, I was expecting Bosch or AEM branding on sensor.
As described. Connection to OBD2 port will be great for data logging and tuning. However the O2 sensor is not a Bosch or AEM item. Looks to be a cheep china knock off sensor. Hopefully it lasts and is accurate.

simplest WB by far and fastest I have owned!
I bought the 30-0334 for my 15 Silverado L83. I also run HPTuners. That being said the simplicity and ease of this OBD2 WB is like no other. Just plug and play really. Plus it’s the fastest WB I have used. Hardest part for me was getting the correct size Fuse splitter. No fault of AEM I wasn’t aware my truck has 2 different size mini fuses. The fact I didn’t have to run a bunch of wires and it has pass through OBD2 sold me. Only wish it were a little cheaper but hey.. the price you pay to be lazy! Lol

Had to order again first one missing parts
The first one I ordered had the "inspected" seal on the box but when I opened it there was not OBDII cable. Which is literally what makes this model (30-0334) more expensive than the others. So sent it back and after a bit of a wait the second arrived and Im happy to say all the parts are here. Just need to install my headers and I will update with the sensors actual performance.
