The Universal Boost Timing Master allows you to adjust the ignition timing in relation to the boost pressure plus it has a built-in inductive ignition. You can adjust the dash mounted control knob to retard the timing 1° - 3° per pound of boost, up to 15 °. The increased spark output of the BTM helps burn the fuel mixture more efficiently resulting in more power - a definite advantage when boost pressure is increasing. The Universal BTM is designed to work with most single coil factory or aftermarket ignition amplifiers and points type distributors.
