Description
Introducing the new X-series widebands from AEM!
This new generation moves the game on. It's fast, really fast for maximum accuracy. It will display AFR or Lambda values with a wider range than before - on gas, it can measure from 8.0:1 to 20:1 AFR. It can output either a CAN signal or a 0-5V signal for use by your ECU.
The controller is integrated into the gauge, which is now less than 7/8" thick. You can see in the pictures how slim it is, this opens up a number of near-flush mounting options. The LEDs are auto-dimming so you don't go blind at night.
Why do you want a wideband (or a wide band)? Normal oxygen sensors are only accurate around stoichiometric (14.7:1) air/fuel mixtures. If you run more rich or more lean, they'll give you misleading readings. Wideband sensors avoid this problem. That's why they're used on every dyno. The kit includes a wideband oxygen sensor, the electronics (inside the gauge unit), wiring and even a bung that can be welded into your exhaust if you don't have one already.

I love the ease of mounting and the perfect fit and appearance of the completed installation.
Good
The afr gage was a simple hat must have on your car if you want to tune or turbo your Miata its has helped out a lot with keeping up on my Miata and making sure the car is running safe .
This is a must have if you are running boost. Installation was easy (already had an exhaust bung). This gauge allowed me to easily diagnose and correct a lean condition under boost which could have resulted in major engine damage with continued driving.
I have been running this kit for some time, eventually did ITBs along with a few other modifications, never had an issue. A week ago from when I posted this, the gauge stopped working, was wondering if it was the sensor or if it was the gauge alone, found out it was a loose ground, this was my fault for the failure, fixed the issue, but the sensor has been reading a little funky on colder start ups, may have to replace the sensor and triple check the tune on a dyno. The kit is good, read about the wideband failures, mine is potentially failing due to my own fault, won't know until I get a pull in. When installing everything, just make sure your wiring jobs are solid. I just had a loose ground that just came up after years of owning this.
