MSD adjustable low-rpm modules allow you to select any rpm between 1,000 and 3,000 by simply turning a knob. They're ideal for vehicles with automatic transmissions that are using the MSD 2-step module to leave the starting line below 3,000 rpm.
They plug directly into the rpm module receptacle on the 2-step module selector, and can also be used on MSD's Soft Touch rev controls, rpm-activated switch, and shift light.
Instructions says chip is currently set at 3,000 rpm.
