Note: The MSD CAN-Bus Hub, PN 7740, is required to connect the PN 7751. Note: The CAN-Bus technology used in the Power Grid Ignition System requires a resistor at both ends in

order to function properly. Do not throw away the Resistor cap, PN 7741, that comes attached to the Power Grid System Controller, PN 7730! It should be attached to the pig-tail of the CAN-Bus Hub, PN 7740, when the Hub is used to add modules.

The Manual Launch Control Module, PN 7751, is designed exclusively for use with the Power Grid System Controller, PN 7730. The Module provides racers an easy way to make adjustments to the launch rpm, and the the shift light intensity without connecting a PC. The Module also displays the engine timing.

Mount the Manual Launch Control Module in a position that allows for easy reach and adjustments. Also, make sure the harness of the module reaches the CAN-Bus Hub. Plug the connector from the Launch Module into an available CAN-Bus receptor on the Hub connector.

Note: Do not cut the wires to shorten the harness. If a longer harness is needed, MSD offers extension harnesses

(2’, PN 7782; 4’, PN 7784; 6’, PN 7786).

OPERATION

The Launch Module has ﬁve basic settings that can each be selected and adjusted using the module’s joystick. Push the joystick in (as a button) to select a setting to be edited or to conﬁrm changes after a setting is changed. To scroll through setting options the joystick should be pushed horizontally (left or right). To edit a selected setting, use vertical motions with the joystick. If a setting is selected to be changed and no action is taken in ﬁve seconds it will automatically deselect and revert to the setting that was initially programmed.

Multiple Manual Launch Control Modules can be plugged into the same system. If one is desired within reach of the driver and another is to be easily accessible to the crew, both will display real time changes.

Launch RPM: This selection controls the Launch Rev Limiter setting. Using the module the Launch Limiter

can be changed in 50 rpm increments from 0-10,000 rpm.

Shift Light: This controls the shift light intensity. The setting is adjustable from 0-100% power 5% at a

time.

Timing: This displays the engine’s timing as set by the 7730 in real time.* This is a Read Only feature. Contrast: The screen on the Launch Module can be controlled for easier reading depending on lighting

conditions.

Rotate: The screen on the Launch Module can be rotated 180° if needed depending on its mounting

position.

*Note: If the Maximum Timing Reference is not properly set within MSD View the 7730 may read and prescribe

incorrect engine timing. Always ensure than the Max Timing Reference matches the timing where the crank trigger is set.
