Programmable Digital-7 w/Boost Retard Curve,
PN 7535
|
The Programmable Digital-7 Ignition Controls are a favorite of drag racers ranging from street classes to professional pro stock racers. With the advances in EFI technology, more turbo and supercharger systems, a lot of racers want to be able to program a timing curve in relation to boost pressure and MSD answers with the new Programmable Digital-7 with Boost Retard!
|
Total Programming Control
|
- Map a timing curve based on boost pressure.
- Plot timing curves down to 0.1° every 100 rpm.
- Control each cylinder's ignition timing by up to 10°.
- Select different rpm shift points for each gear shift.
- Program a specific timing curve for each gear.
- Three stages of retard for multiple nitrous systems.

The new ignition has a MAP sensor Weathertight connector that plugs into most GM style MAP sensors (not included). This information lets the ignition's microprocessor know the exact boost pressure. From there you can set up a curve down to 0.25pisa increments for every 0.1° through the MSD software on a PC or with the optional hand held monitor (PN 7550). All of the features racers have come to expect are still included in the Programmable Boost Ignition. This includes individual cylinder timing, stage retards, rpm limits, shift points and more. The race proven output of the ignition is a stout 190 millijoules of spark energy with a primary voltage of 535 volts. Plenty of omph to light a fire in a cylinder with high boost pressures! For even quicker computations and management capabilities this ignition uses a 40Mhz RISC microprocessor – the most powerful of any digital ignition!

The Pro-Data+ softwareis easy to use and installs to any Windows based PC with 95, 98, 2000, NT, XP or ME. The Boost Chart is easy to program by a click of your mouse to add or remove a point at a specific pressure and timing. There is also a boost pressure gauge along with a retard dial and a tach so you can view the boost and timing changes as they occur in real time.
AMAP sensor is required for the boost circuit. The Ignition is supplied with wiring harnesses, mounting hardware, an RS232 computer harness and the Pro-Data+ software on a floppy disk. (The Hand Held Monitor, PN 7550, can also be used for programming.) It will accept trigger signals from a points/ECU output or a magnetic pickup. The recommended Coils are PN 8251 or PN 8261.
Map Sensor
An MSD MAP Sensor is required for the Boost Retard feature. Be sure to know the approximate amount of boost you will be running so you will get the proper sensor. MSD offers three different sensors.
