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 of a car consists of many components, including the engine, transmission, driveshaft and any of the internal workings of the engine. Powertrain management is a function of the electronic control module (ECM). Depending on the car, the ECM may also be called the powertrain control module (PCM).
