MSD 4224 Programmable MC4 Drag Racing Ignition Control Box

Product Description

MSD'S programmable digital-7 series ignitions have been powering the winning cars in NHRA pro stock, outlaw super street and pro street classes for years. That technology is now offered to motorcycle racers with the mc-4 ignition control. It provides incredible output and energy, along with pc programmable capabilities that give you great tuning opportunities. The mc-4 provides the spark energy you expect from MSD with over 190 mJ of spark energy to each coil to fully burn the fuel mixture of high output race engines. Below 3,300 rpm the mc-4 delivers a long series of multiple sparks that burns in the cylinder for 20 degree to keep the engine crisp and clean at lower rpm. Every spark is at full power even through redline rpm to ensure the most power through top end. All of this spark energy can be controlled through an array of timing and rpm controls. The mc-4 is programmable with MSD's pro-data+ software so you can custom tune your timing and rpm parameters.

• PC programmable for custom curves • Individual cylinder timing adjustments must use a cam sync sensor • Timing launch retard • Three independent step retards • Boost retard curve up to 45-psi manifold air pressure sensor not supplied
