MSD-8737 - MSD 3-STEP MODULE

The First module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the limit turns off.

You can activate the Second limit through the clutch or trans switch when you're on the starting line. This provides a steady and consistent RPM for firm holeshots every time.

When no modules are selected, the Third high limit is active to protect the engine in the event of driveline failure.

 The Module Selectors can also be used with an MSD Timing Control. By plugging the Selector into a retard module socket, you can activate different retard amounts at select times. This is a great feature for engines being upgraded to a multi-stage nitrous system.

With the addition of an RPM Activated Switch, you can use the Two Step to activate a shift light at different RPM. The Module Selectors must be used with an MSD Soft Touch Rev Control or a Timing Controller with a high-speed retard module. No RPM or retard modules are supplied.
