Hall Effect Sensor - Racepak PN 800-SS-MSC-5
Driveshaft Collar - Call Racepak
The Advanced RPM Control Module (ARC), PN 7761, has been designed to help prevent excessive
wheel speed. In the event that engine and / or driveshaft rpm increase(s) at an undesirable rate the
module’s software will retard timing and/or rev limiting in order to prevent excessive wheel speed.
INSTALLATION:
The ARC Module should be securely mounted near the MSD CAN-Hub. Plug the ARC CAN connector
to an available port on the MSD CAN-Bus Hub, PN 7740. Do NOT cut the CAN-Bus connector wires.
The driveshaft sensor must plug directly to the 7761 module. MSD recommends using an 8-magnet
driveshaft collar. Using less than an 8-magnet collar will result in less data for the processor to
work with and slower, less reliable corrections.
When connecting to a Racepak Data Recorder, the White/Blue and Brown wires will be connected
to the driveshaft input on the Racepak. The wires (White/Blue and Brown) do not have a connector
on them from the factory; two connectors are included in the parts bag of the module. Select and
install either the 2-pin or 3-pin connector depending on which style is required by the data recorder
being used. To install, push the pins (pre-installed on the wires) into the proper hole according to
Figure 1 below. If these wires are not used, terminate the wires using heat shrink so that they cannot
create a short.
The Yellow output wire is included in the same loom as the driveshaft output wires. The Yellow wire
will switch to ground any time the ARC is controlling timing or rev limiting. The output circuit can
support up to two amps continuous. This can be used to activate a light, solenoid, or boost controller.
