K+R Performance Engineering PRO-CUBE Installation And Operating Manual

Congratulations on your purchase of the most advanced combination delay box/timer unit available for
today's precision drag racing. The PRO-CUBE Ò has been designed to give you unprecedented control of
your reaction time and ET with a host of standard features, plus options for up to three general purpose
timers, all in one super-compact unit that can be mounted almost anywhere. The precision available with
these timers makes them perfect for controlling a variety of equipment including throttle stops, shifters, and
multi-stage nitrous systems. You should read and understand this entire manual, including the warranty
section beginning on page 8, before proceeding with installation.
STANDARD FEATURES
Cross-Over:
open tree. The delay time is automatically calculated from dial-in and delay values you enter.
Second Hit:
having two delay boxes in one. This feature allows you to take two shots at the tree in long cross-
over situations. You will launch on the faster of the two reactions.
Bump-Down Ò:
after releasing the transbrake switch. You can program the amount of time to subtract, you can
bump-down any number of times, and you can use it for either one or both hits on the tree. In
addition, this feature can be used on Timer 1 during the run. If you have a throttle stop connected to
Timer 1, the Bump-Down feature will allow you to correct for track conditions such as tire spin by
reducing the stop time.
Flinch Protection Ò:
release the transbrake switch before the tree starts.
Run Info:
automatically be displayed to indicate the difference in your reaction times for double-hits, as well as
the number of times you bumped-down your reactions and the number of times TIMER 1 was
bumped-down. This allows you to determine what your reaction(s) and E.T. would have been had
you not used these powerful features.
Transbrake Output:
release solenoids. Handles up to 25 amp load.
Line Lock Output:
includes a blocking diode to prevent back feed into the transbrake circuit. It can be used in front
wheel line lock applications or jumpered to the Pro-Stage ä or one of the timer outputs acting as a
"launch control" when connected to a compatible throttlestop. Handles up to 2 amp load.
Transbrake Lockout: A built-in timer prevents activation of the Transbrake and Line Lock outputs for a
programmed amount of time after the transbrake releases. This timer can be set from 0 to more than
an hour. Transbrake activation is automatically re-enabled when the timer completes.
