Digital AFR meter review

Summit RacingSummit Racing Verified Purchase

Very useful. Connect 12 volts (cigarette lighter), O2 sensor and drive. I was able to accurately set the AFR at idle, cruise, and WOT. I can now pass the smog test on the 1st try; guessing does not work very well. I should have purchased the AFR meter years ago. 1978 Corvette

Works great, looks great, and easy to install

Summit RacingSummit Racing Verified Purchase

Installed this on my hot rod last year to tune the carb with and it works great. Before I tuned the carb it was only getting 10 mpg and was fuel fouling the plugs within a couple thousand miles. Now it gets over 15 mpg and never fouls the plugs. Every hot rod I do from now on will get one of these. It also looks great and installation was real easy. ...read more

Great product for the money

Summit RacingSummit Racing Verified Purchase

Bought this setup to help with the tuning of my car and it works great. Very easy installation. This kit is a real value compared to the other widebands that are close to the same price for the gauge alone. Well worth it.

Excellent tuning device for EFI

Summit RacingSummit Racing Verified Purchase

Works well with aftermarket EFI computers. Makes EFI tuning across any RPM much easier. Very accurate, repeatable and easy to read.

Easy to install, works like it should!

Summit RacingSummit Racing Verified Purchase

The gauge includes everything needed for install and more. The one thing I did need to buy extra was a heatsink for the sensor. My bung was already mounted too close to the turbo output, so the heatsink prevents the sensor from overheating. I like the included options of being able to swap the gauge face color and ring bezel to match your car. So far the gauge/sensor is functioning very well. I can see the engine operate in open loop mode when cruising and I can see the A/F ratio in closed loop mode when full throttle. ...read more

Worth every penny

Summit RacingSummit Racing Verified Purchase

Recently install this product and now don't know how I ever got along with out one. Well engineered and thought out gauge especially considering the relatively low price compared with others on the market. 100% satisfied.

Nice product

Summit RacingSummit Racing Verified Purchase

Bought this cause it had good reviews and so far I agree it's a decent product for the price and easy to install but how come there's no under dash mount?
