Scooter this is from MSD. Info on the programmable Digital 7.
With this box you can set up any kind of timming curve you want. Add or take away timming at any time during your run. I've never had one, but gonna get one for for next truck.
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 Retards: Three steps of retard that can be activated with nitrous solenoids or switches.
Gear Retards: Program a timing retard up to 5° with every gear change!
Start Retard: Ease engine cranking with an adjustable retard during start up.
