    MSD 7AL-2 Plus features a built in two-step rev control and diagnostic LED. This ignition delivers full power at any RPM. Multiple-spark discharge circuitry improves throttle response, off-corner performance, idle, and launch consistency. Built-in, soft touch rev control protects the engine from over-rev damage. The 7AL-2 Plus' accurate rev-limiting action is smooth without backfires. Adjustments are easily made with plug-in modules, and the ignition can be triggered from points, magnetic pickups, crank triggers, and electronic amplifiers.

    With MSD's race winning experience and performance ignition knowledge, the Programmable Digital-7 is THE ignition control.

    No Timing Compromises
    Ignition timing is always a compromise between cylinders. The dynamics of the flow of air and fuel into each cylinder is never exactly the same no matter how much machining magic has been done. This has always caused top engine builders to compromise their ignition timing. With the Programmable Digital-7's advanced Individual Cylinder Management system and other exact timing programs you will never need to compromise again.

  • ICM Timing Control: Adjust the ignition timing in each cylinder Program up to 5° of timing retard into each individual cylinder in 0.1° increments.

  • Run Curve: Plot a timing curve in 0.1° per 100 RPM throughout the entire rpm range of your engine.

  • Launch Curve: Program a timing curve exclusively for the launch If the starting line conditions are less than adequate, you can set a completely different curve for the launch.

  • Launch Retard: Retard the timing up to 15° for 0-2.5 seconds after you launch the car.

  • Step Retard: Three steps of retard that can be activated with nitrous solenoids or switches.

  • Gear Retard: Program a timing retard up to 5° with every gear change.

  • Start Retard: Ease engine cranking with an adjustable retard during start up.

  • Traction Control Detection: The TCD monitors the magnetic pick-up input signal and if it senses that the signal has been modified, it will set a trouble code and flash indicating that traction control has been detected.

    Power
    No other ignition system comes close to matching the output power and the Individual Cylinder Management timing system of the Programmable Ignition. To effectively handle all of the ignition's tasks, a 15 MHz microcontroller, reviews, manages and analyzes every trigger signal up to 15,000,000 instructions per second Capacitive discharge circuits combined with an IGBT Coil driver deliver incredible cylinder pressures. Below 3,300 there is of course MSD's powerful series of multiple sparks. This spark series burns in the cylinder of over 20° of crankshaft rotation resulting in improved combustion for a smooth idle, great throttle response and increased power.

    RPM Controls
    Monitoring the engine's RPM allows you to set shift light points, activation points and rev limits. The Programmable Digital-7 has MSD proven Soft Touch rev limiting controls built in and lets you program several RPM features.

  • Three Step Rev Control: Program three rev limits in 100 RPM increments for burnout, launch and overrev protection.

  • Shift Light: Program a different RPM setting for each gear change for up to six gears.

  • RPM Activated Window Switch: Activate a circuit at an adjustable RPM such as a nitrous solenoid, then set another RPM level to deactivate the same circuit.

    Easy Programming
    Don't let all of these accessories and adjustments worry you. MSD engineers developed two very useful and easy ways for you to program the ignition. You can use the hand held programmer or MSD's Pro-Data+ Software package on your PC. The Programmable Digital-7 Ignition Control can be triggered with a points/ECU trigger, magnetic pickup in a distributor or a non-magnetic pickup of a crank trigger. There is even a mag pickup compensation adjustment for absolute trigger accuracy The single unit is fully potted for vibration protection and is easy to mount. It can be used on 4, 6 or 8-cylinder engines and is supplied with the Pro-Data+ software, PC harness, vibration mounts, wiring and thorough instructions.

    Note: MSD 7-Series Ignitions are not compatible with distributorless systems.

    Rated 5 out of 5 by from great product I replaced my old 7al-2 with the newer model 7al-2 plus and my 3 step plugged right in and it was a quick swap at the track.
