New Out of Box, Jacobs Electronics Uphill Power Module.

The Uphill Power Module, or UPM for short, connects to the Pro Street, Off-Road, or RV Energy Pak and modifies the Energy Pak's digitally controlled spark output upon sensing a vehicle's tilt or angle. This increased spark output results in significantly better throttle response and eliminates plug fouling caused by extreme angles.
