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.
A: An ignition control module is a component in a vehicle's engine that enables a spark to be produced at the correct time in each cylinder. It does much the same job as contact breaker points did in older cars. Ignition control modules can fail, which can lead to overheating.
