How to determine compatibility?
There is a sticker or nameplate on the frame of each device with model and serial number information. The adaptability of most parts is model-based, which means that these parts are only suitable for specific series of manufacturing equipment. Please carefully verify the compatibility of this kit with your model before purchasing.
- Confirm compatibility by model number (each device has a specific set of parts for that model).
- Do not match by brand or image (parts compatible with your brand may not be compatible with your model).

I purchased this product in April of last year. I just recently put it on a motorcycle I have owned for thirty five years (1986 Yamaha Vmax ). Within one hour of driving it the whole front fell off the gauge. I am an accomplished motorcycle mechanic. I know this product is out of warranty but I felt it important to tell you about this mishap so that you and your company can make changes to fix this problem. Before the face fell off the gauge it worked perfectly.

Been working spot on for over a year no issues. Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate.

Works fine and has been working on a C4 corvette. I've been tuning a 406 wth a mild cam and seems to to accurate. Engine seem lean when guage says it's lean. It's respond quick and I'd 100% buy this again.

Let’s be honest. We all know what this a copy of.I bought 2. The gauges work great. I had one sensor bad which is common. Seller refunded me the cost of one sensor I had to replace. Great to deal with.

This controller worked great last summer, but is now dead. The screen is blank. I verified power and ground and tried disconnecting and reinstalling it after waiting a few minutes with no change. I see the seller offers a 24 month warranty, but even though I still have the manual, I can't find any contact info.I would definitely raise my rating if the seller sees this and honors the warranty.Update: The seller sent me a message wishing to honor the warranty with a replacement within 1 day of this post.

Looks great. Almost as good as the aem wideband. But not even 15 minutes after installing it in my exhaust it quit working. The gauge still lights up but the sensor does not read at all. The o2 sensor is no good. Very cheap quality. Would really ask for my money back but its already been installed and I don't think they will take it back. Would be great if they sent me a new sensor. We will see.

If you read the reviews you know that this gauge comes with a garbage o2 sensor. But it doesn’t matter because it’s still the cheapest way to get a reliable system. Just don’t use the included sensor if you can’t meet the requirements for it to function. They state clearly in the directions that it must be a certain distance downstream and never exceed a relatively low temperature and only be exposed to a somewhat narrow A/F ratio or it will ruin it. Normal o2 sensors are usually mounted far closer to the motor and drastically exceed the rated temp. So basically, toss the included sensor and purchase a new Bosch o2 sensor part number 17212. It’s the cheapest wide band they make at 59.99, and is available at most reputable places. Then just install it in the original port in your exhaust and bam! Perfectly accurate and reliable system for a fraction of the name brand stuff. Gauge works great, which is not surprising since it is a simple electronic system that only shows the output voltage from the sensor via readout/indicator lights on the gauge face.Would be great if it were even cheaper by being available without the junk sensor.Also! I’ve been running this kit with the Bosch 17212 for a while now with no problems at all.

Installed this wideband over a month ago and still no issues. Wiring is easy. You MUST ground it to the chassis. If not, it will not work properly.Edit: My sensor failed like stated in other reviews. Just ordered a Bosch sensor. The gauge works fine so I'm still happy with the product.

Does it work? IDK. As I was laying out the parts, I realized that even though the part number is the same as the genuine AEM gauge and the instructions are a copy of (most of) the AEM instructions, that the O2 sensor is not a Bosch unit and the Faceplates are mixed up. The Lambda labeled plate has AFR graduations and vice versa for the AFR faceplates. So I put it back in the box and ordered a genuine unit from Summit
