FAQ
What RPM does the MSD ASY11216 module set the ignition to cut out at?
It is a fixed 6,000 RPM module — the ignition box cuts spark once the engine reaches 6,000 RPM.
What does this module plug into?
It plugs into MSD ignition control boxes designed to accept interchangeable RPM module chips.
Can the RPM limit be changed later?
Not on this module — it is fixed at 6,000 RPM. Reaching a different rev limit requires swapping in a different MSD RPM module.
