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.
The powertrain control module is coupled to controls an internal combustion engine and an electronic throttle. A main microprocessor is located in the powertrain control module that includes control logic operative to monitor and control the internal combustion engine and derive the desired throttle position.
