MSD Ultra 7AL Ignition

For racers that need serious spark output, the new ULTRA 7AL is the right choice. Offering Industry-Leading Spark Energy Output in a compact, and efficient package. The Ultra 7AL includes four-step retards, three rev limits, and two RPM-activated switch outputs. The ULTRA 7AL also features two different power output settings that can be used for on-the-fly changes which are perfect for drag-and-drive applications! All features are adjusted using plug-in modules including the 3-Step Rev Control and Multi-Step Retard. The Rev Control allows you to set one rev limit for the burnout, another for the staging rpm limit, and a third for top-end engine protection in the event of driveline failure. Four separate stages can be activated independently for nitrous users as well. Plus, two RPM Activated Switch outputs can be used for air shifters, shift lights, or other devices that require a perfectly timed ground trigger! The MSD 7AL also features an adjustable start retard giving you control over the amount of retard pulled out during cranking.
