MSD set the standard in programmable ignition systems. In fact, every NHRA pro stock championship in the last few years has been with an MSD programmable 7. Drag radial, twin turbo outlaw cars and 10.5-tire classes all rely on the advanced programming of MSD's programmable 7 ignitions. Wait until they see the power grid. The power grid ignition system is the next evolution of our programmable 7-series ignition controls. The grid incorporates an efficient 32 bit micro controller and an all new software program, called MSD View, and is USB compatible. The windows based software is designed with tabs to help racers easily select different programming windows and parameters. Also, the data acquisition files of the ignition are now captured on a micro SD card for ease of storage and reviewing. The power grid ignition incorporates CAN-Bus technology which reduces the amount of wiring and simplifies the addition of accessory modules. All modules connect via CAN-Bus technology.
