Innovate Motorsports 3918 39180 MTX-L Plus: Advanced Digital WIDEBAND AIR/Fuel Ratio Gauge KIT, 8 FT. Sensor Cable

Works great and and the response time and signal level are excellent. Setup with my Miata and a speeduino EFI, it's important to note that this product has no analog signal from the sensor, if you plan to connect this to the ECU, the signal comes from the Gauge. This would be cool, but my little miata didn't have enough power and the gauge was rebooting during crank. Added a voltage stabilizer to resolve that issue and its all good now.

Zero complaints! This gauge delivers which from experience I can say isn’t true for another big name.

Installed on a '75 Celica with a built and forged carb'd 22R/20R hybrid to help with tuning. Worth the money to take out the guess work with jetting. Had one of these on a single turbo FD RX7 before as well and never had a problem.

Worked for 2 days. Then the readings are way off. Tried calibrating it multiple times.Calibration went through successfully, but the readings are still off. Hooked up a different gauge and the 2nd gauge from a different brand reads correctly while the innovate doesnt.

Clearly takes some installation experience but all in all the install was easy and it works as advertised, helped me to diagnose my rich running problem and now I can add nitrous.

This guage works as expected and is very user friendly/straight forward to install. The only thing that I rated it 4 starts for us because it comes with the connection cable wich is a serial cable yet you need to get an adapter to be able to connect it to your computer so be aware if you plan to do any data logging or having your car remote tuned like I am. Now I have to wait for the adapter to show up before I can finish having my car fine tuned.

Excelente! Marca perfecto. Es importante saber ubicar bien la sonda.

Installed on my jet ski so I could adjust the fuel, and it works great.
