R-Speed Air/Fuel Ratio Meter. This thing measures the O2 Sensor signal to the ECU telling the ECU to enrich or lean the fuel sent to the cylinder. Basically, you get to see what the O2 sensor is telling the car. And you get to tell in real-time the fuel performance of the car.

I love the product. It's a great performance indicator, and it looks cool when other gearheads gather at your car.

Installation was easy. The Instructions that R-Speed has written are Miata specific and they're very clear. There is even an insert telling you how to read the meter and what everything means. If you have any problems, they are eager to talk on the phone with you for any advice. I think it took me like 30 minutes to install and mount it.

One of the cool features about this is that its 5 different colors. No other meter that I've seen does this. So it's easier to be aware of the meter in your peripheral vision.

What I really like about the product is that it dims with the headlights. The display lights are really bright for visibility during the day (especially for convertibles with the sun beating down, you need it that bright) and you need it to dim at night. So it does. I haven't seen any others that do this.

Everything was great. I loved the service that I got. I love the meter. I love the instructions and the extra information that I got. I recommend this to everyone. Especially, if you have fuel management equipment or turbos or superchargers.

Under 30 minutes to remove completely
