## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome AFR Sensor!
*by S***A on March 12, 2021*

Make sure you follow the calibration process precisely. Also, for the money this sensor costs, do yourself a favor and order the NTK sensor.Calibration is easy. BEFORE installing this in your bung, connect it and let it hang in free air with the sensor turned on, but the engine off. It will be extremely hot, so avoid the temptation to lick it. The instructions say 10 minutes, but the longer the better. I let mine sit for 45 minutes. While it’s calibrating turn the dial on the back until it reads “CAL”. Small movements with the dial, it doesn’t take much. You’ll have to tweak it 2 or 3 times during the process.Once it’s done, let it cool off, disconnect the Harness from the sensor, screw it into the bung and then tighten it down.This should be powered from something keyed so it’s always on when the car is running (it will get ruined if you don’t). It also needs to be grounded to the battery. If you can’t do that, ground it to something without interference so your reading is accurate.

### ⭐⭐⭐⭐⭐ Hope you can read a manual
*by J***Y on June 13, 2020*

Not perfect accuracy when logging with hp tuners close enough. Way more complicated when you have to figure everything out yourself. Because there is no support for this no community no videos. Any forums you ask don't even know what this is no nothing about this product except their official website. It does do a good job.

### ⭐⭐⭐⭐⭐ Great wideband
*by I***N on April 26, 2024*

I have 2 of these afr500v2 units i purchased from the website. I use them almost exclusively while tuning. Highly recommend any ballenger product.
