        Bought to help tune a 71 Vette w/Edelbrock Thunder series carburetor. It has helped with setting the idle/mixture and WOT AFR. I bought the exhaust clamp so I can use it on other vehicles also. Like they state it's having a dyno at a lower cost and I can use it anytime.

        So far works well. The manual will take some thought on adding sensor inputs. AFR changes fast. Had to space the sensor out. They supply a spacer to weld in with the correct spacing. Adding a map sensor took some thought. Used a buck voltage convertor for the 5 volt power. They had a forum on their website but stopped it. I think that would have been a good place for advice. They do give a support phone number. It take an SD card. Hard to find a standard card. Won't work with high density cards. I ended up buying the case and wire harness. Recording is worthless without rpm, vacuum or whatever data you would use on a carbureted engine.

        If I could give this 10 stars, I would. I've worked on engines for almost 50 years, and still work on classic cars ( meaning carbureted) . I've used the "plug chop and read" method all this time with fair results. I now live at 7500' altitude and like to drive from here to the mountains and back in a day or two drive. Some cars stall out on drives to 10,000+ feet from fouled plugs.

        I can finally log using a wideband that doesn't require a special RS to usb adaptor. I initially had problems but Innovate helped me along the way and their customer service is excellent. If you are having problems installing the necessary drivers, save yourself the trouble and just give innovate a call and they will walk you through it. I can finally log on my bmw e36 turbo using this wideband and bimmerlogger!!!!!! Thanks!

        Purchased this gauge so I could install an AFR sensor for my piggyback ECU to monitor and adjust, I had high hopes for the price point and was not disappointed. The 4 face configurations is really neat and love the fact it came with white ones to match my interior (as shown, sorry for the crappy panoramic photo). The sensor wire, and the gauge wire to the sensor were both plenty long, and wiring in the power wire was super easy, it also includes a monitor wire (like use for the ECU) and a serial wire on the power line pin connector. Overall I am very satisfied with the quality and performance of it, the readings are instant (it changes with the slightest chance in throttle so virtually instant). Would buy again without a doubt! Also includes very detailed instructions which was super convenient.

        As always it was delivered in true Amazon fashion, nearly before I ordered it. The gauge response time is almost non-existent, it's so fast. In fact if I have any complaint, it is the LED needle is way too responsive, it needs to be dampened a little so it is more apt to display an average, but with a short decay time. Other than that I am 100% pleased and look forward to using it when I add the turbo. Thanks again Amazon, and of course AEM for their superior, yet affordable products. <:/)

        This has worked great on my race car for several weekends. Love the fact that it does not need to be calibrated in clean air like some others. I have 2 Innovate Motorsports Wideband gauges on other cars and they seem to constantly need to be re calibrated and to do that on them you have to remove the O2 Sensor and that can take 20 minutes. The next one I buy will be a AEM.

        Exactly as described. New style Bosch o2 sensor seems to be a bit more accurate. Also has a light exposure "eye" that adjusts the display brightness so its not blinding at night or dim in the sun. AEM has always treated me right.

        After install this gauge in my 91 Miata turbo to monitor the air/fuel ratio it only worked for few mins then it went to full lean that gauge showed "---". I contacted AEM customer support and Matt Cruz pickup my email and walk me through the diagnostic steps to troubleshot and find out the gauge is defected and I received a brand new gauge set with FedEx return label the next day. Now AEM will be the first merchant I go to for my cars performance electronic needs. Highly recommended.

        AEM is a well known company in the car world, and makes high quality products. I purchased this gauge to monitor my AFR and log for open source tuning purposes. Installation was painless and took roughly 20 minutes since my downpipe already had a bellmouth o2 bung. I strongly recommended that you buy an add-a-circuit fuse kit (ASIN B01LFXA5UA) if you don't have any, it will make installation much easier so that the gauge can be powered by one of your car's powered circuits, like the radio. I had a few spares laying around, so I spliced this gauge and a boost gauge to one fuse kit without any problems. The kit also comes with several butt splices although one would suffice. The cables for the gauge are extremely long, so be aware that you must have adequate room to tuck them away. I paired this gauge with an AEM boost gauge (ASIN B001DX7KMY) and SMY Dual Gauge Cluster (ASIN B01M7MEKUS). The numbers are also very readable in the day time and stand out in the night, although the sweeping color band is a bit washed out during the day but still visible. No issues with this gauge and I'm very pleased! The AEM sticker that came in the box was a bit damaged, so I only gained +4 HP instead of the expected +5 HP.

        My tuner recommended this wide band so he could see how things were running at cruise and WOT. The installation was simple and straight forward. I did have to disassemble the harness from the O2 sensor to pass it through the hole I drilled in the firewall, but it went back together without issue largely. I did have a pin get pushed out which caused the meter to stick on 14.7, but I found where it backed out because I didn't put it back in all the way. After fixing that, it's been great. I am also using a SCT fire wire connection to log the data and everything has worked beautifully.

        I have been looking for a AEM wideband AFR gauge for a while now and i finally saw this on Amazon for an awesome price. They usually go for more than $200. This gauge works perfectly and is an authentic AEM gauge. It comes with 2 gauge face colors, black n white, and it includes all wiring needed for installation and easy to follow directions.

        Simple installation and works great. Very easy to read digital and range LED graphics. I am using it to tune and monitor an older twin carbureted engine. It is sensitive enough to quickly read ratio fluctuations so it does jump around under normal driving, but I prefer it like it is to get a feel for how the carbs transition under acceleration etc. I am very pleased overall.

        Bought this to put on a 1915cc VW powered sandrail with a 2 barrel carb. This thing is an engine saver. The jetting was all wrong in my carb so I changed all the parts out and it runs better than ever before. Important that you dont mount this near the exit of the exhaust because you will get inaccurate readings

        It was as expected I got it for 25lb of boost running E65 on a 1.4T. It reads fairly accurate for expected values. Little bit on crimping or soldering connections you install but ultimately it works well, goes through set up quickly, and hasn’t had any issues in the first month of use. Product arrives as expected.

        Looks like it is built pretty decent, though the case is a very cheap plastic and would of preferred metal but seems everything is plastic nowadays. I installed it and the sensor screwed right into my existing bung. The threads are precoated with I think is anti-seize. The sensor cable is plenty long enough for my application and I probably will end up with a glove box full of rolled up cable. Once I get it running, I will try to update my review here.

        Easy to install, straight forward and I love how much wire they provided. After I neatly installed the gauge, I had plenty of wire to wire tuck and to hide it away out of sight.
