   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.

   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!

   This is by far the best tuning tool you could ever purchase. It is a must for getting the most performance from your setup! I was amazed at how bad some of the cars were running that I thought were tuned well.

   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.

   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.

   Great kit, comes with o2 sensor, the wiring was a little shirt for my application, running from the dash to the exhaust on a rear engine buggy

   It was easy to wire into my hand held SCT X4 tuner which allowed me to log the air/fuel ratio. Overall, would like to be able to tune the signal output to allow a less noisy data set and more stable readings.

   Brand new in box. I have bought this item before from rally sport for my STI this came in faster and for less. Granted the sensor was DOA but the seller sent out a replacement ASAP with a return box. Everything worked out well.

   This thing is awesome. Amazing quality. This thing does its job and thats exactly what you want from this gauge. The data this gauge delivers is very important and it does it very well every time. Very reliable and simple. Interchangeable bezel is nice too.
