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.

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 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.

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.

Good product
The actual gauge worked great! I used it and when I hooked my hp tuners datalink mpvi2 to it it burned the Gauge up, I thought it was something with the way I had it hooked up because I didn’t have it on a fuse so I ordered a second one and wired it right with the fuse and everything and when I went to tap into it again it didn’t come one and started smoking. Pulled them both apart and it burned the same exact pin on both on the circuit board. If you have the can bus in your ecm it’s a perfect gauge, but if you have an older ecm and have to have the datalink it won’t work I’ll look into a different one I guess idk.

As expected
Can't expect anything less from one of the best aftermarket parts and accessories manufacturers
