MSD Power Grid 3-stage delay timing controls are an add-on module for use with the MSD Power Grid system (sold separately). These controls let you activate up to three individual outputs based on time. The outputs can trigger a relay to activate nitrous, shifter, etc.; when the clutch/transbrake is released, the Power Grid will start the timers through the CANN connection. They'll also display live ignition timing! Thanks to the advanced data acquisition features of the MSD Power Grid, all of the settings and values you set with the 3-stage delay timer can be reviewed after each run to assist in tuning the program for the next run. Now that's timing control!
