Today, you can utilize the live data function to check thermal efficiency, fuel economy, and general engine performance. It’s cheaper to use OBD2 scanners to look into this live data of a car rather than sending your car for testing. When you decide to use OBD2, you can have a good idea of the performance of the car’s engine.

As a result, you can save tons of money and time. Therefore, if you want to check the efficiency of your car, then there are a couple of things you should look into. This article discusses what you need to know about OBD2 scanners.

Fuel economy

You should always make sure that your car’s engine is utilizing the correct rate for the car. Remember that if the car’s engine is utilizing a lot of fuel, the engine can have a low economy and it can be more expensive to operate. An engine that is using a lot of fuel can mean there are some problems with its fuel system.

This is the time to use an OBD2 scanner to check the fuel economy. An OBD2 produces Fuel Trim which is part of the live data that is displayed on the device. Fuel trims refer to the amount of fuel that is being released into the car’s engine by the fuel delivery system.

It’s worth noting that fuel trims of the OBD2 screen come as a percentage. Therefore, 0.0 percent means that the fuel system is working properly. Visit https://obd2pros.com/scanners/ to learn more about OBD2 scanners.

On the other hand, a positive number can mean that there is too much fuel that is being released. Also, if there is a negative reading, it means the fuel system is releasing too little fuel.

That said, an OBD2 provides a long-term fuel trim and short-term fuel trim. Both of these mean the same thing, but the long-term fuel trim tends to be calculated over a longer time.

Engine RPM

Revolutions per minute (RVM) is also a good indicator of the efficiency of your car’s engine. Keep in mind that all OBD2 devices need to display the RPM of the car’s engine.

Many cars nowadays usually have idle speeds that start from 600 RPM to 1000 RPM. For the trucks, the idle speeds are about 600 RPM while motorbikes can be higher to about 1200 RPM.

It’s a good idea to check the handbook offered by the car manufacturer or you can research your car online to determine the RPM of its engine.

Technically, if the RPM of your car is too high, this can cause your engine to be less efficient. And, if the RPM of your car is too low, then it can’t generate the correct amount of power to make it less efficient.

Likewise, if the RPM of your car is too low or too high, then it can be a problem with a vacuum leak or idle control valve. As you can see, an OBD2 scanner can be helpful when it comes to checking these problems.
