• Overboost shutdown.
• Spool boost rev-limiter control.
OVERVIEW
The Boost Control Module allows fine tuning control of the engine’s manifold pressure (boost) in forced
induction engines by managing the pressure on top of the wastegate through a set of electronically
controlled air valve solenoids. The Module integrates with the Power Grid Controller seamlessly
through the 4 port CAN-Bus connector which minimizes wiring.
All Power Grid Modules work through MSD’s CAN-Bus system. The Power Grid Modules are plug
and play installations but may require extension harnesses for remote wiring.
Note: Do NOT cut the wires to the CAN-Bus Harness. In the event an extension harness is needed to
mount the unit in the desired location MSD offers the following extension harnesses-
2’ CAN-Bus extension PN 7782
4’ CAN-Bus extension PN 7784
6’ CAN-Bus extension PN 7786
The module has several programmable features such as Over Boost Shutdown, Spool/Launch RPM
activation once the spool pressure is achieved, Data Acquisition through the Power Grid Control,
and allows for two separate Boost Control Curves for “on the fly” switching. The Module utilizes the
built in data acquisition function of the Power Grid for fine tuning of the Boost Control Curves and the
Boost Retard Curve. The module uses two 75 psig sensors to monitor and data log boost pressure.
