7AL-3 Multiple Spark Ignition Control Box

For racers that want adjustments at their fingertips, the 7AL-3 is the right choice. The 7AL-3 packs high voltage with four step retards, three rev limits and an rpm switch. All of the features are adjusted using plug-in modules including the 3-Step Rev Control and Multi-Step Retard. The Rev Control gives you the ability to set one rev limit for the burnout, another for the staging rpm limit and a third for use top end engine protection in the event of driveline failure. For nitrous fans, there are four separate stages that can be activated independently yet add up together. Plus there's an RPM Activated Switch for precise control over a circuit. Something new is that the start retard is now adjustable with plug-in modules giving you better control over the amount of retard pulled out during cranking. The unit is supplied with a variety of rpm and timing modules. It is has a foot print that fits into the red 7AL-3's mount.
