MSD 6AL IGNITION CONTROL
The MSD 6AL has built in Soft Touch Rev Control to protect engine from overreving. The Rev Control measures the engine RPM and at the limit, preselected with plug in modules, it randomly drops spark to some of the cylinders. On the next cycle those cylinders are fired to prevent loading with fuel. Rev limiting is very smooth and precise without backfires or roughness. Supplied with 6000, 7000, and 8000 modules - others purchased separately.
