GMC Ignition Modules

Q: What is an ignition module? Why buy one?
A: According to About.com, "An ignition module is the electronic control for the ignition system. The module receives a signal from a magnetic pickup or sensor in the distributor. The module uses this signal to open and close the ground circuit to the ignition coil to fire the spark plugs. The ignition module itself may be located inside the distributor, on the distributor housing, or in the engine compartment. Aftermarket performance ignition modules also control timing advance and retard, which can have an impact on your car's performance. Two more great features in some modules are the rev limits! There are two rev limiters on your car: one for high end over-rev protection and another you can activate off a clutch or transbrake to set a launch limit. This ability to adjust the rev limits will help your car blast off the starting line.
