Bradycardia = too slow. A heart rate of less than 60 beats per minute (BPM) in adults is called bradycardia. What's too slow for you may depend on your age and physical condition. Physically active adults (and athletes) often have a resting heart rate slower than 60 BPM but it doesn't cause problems and is normal for them.
Using technology similar to the Jet PCM, the Jet module provides the ultimate in power tuning. Point-by-point air/fuel, ignition advance, transmission, and various other tuning points provide performance gains and, in some cases, improved fuel economy.
Quick Answer. A car's electronic control module is the computer responsible for providing fuel to the engine and controlling the quality of the car's emissions. The ECM uses a microprocessor and software to analyze and respond to the input values from an array of sensors. An ECM is typically part of a larger system, with multiple modules that control everything from power steering to airbags, commonly called the car's computer.
