Overview:

The Banks Power Derringer Tuner is a sophisticated performance tuning solution designed specifically for Jeep Grand Cherokee and Ram 1500 models equipped with the 3.0L diesel engine from 2011 through 2021. This advanced tuner delivers noticeable torque and horsepower gains across the entire rpm range, starting from idle and extending through each gear’s shift point. Ideal for enthusiasts and professionals alike, the Derringer enhances vehicle responsiveness, improves acceleration, and optimizes engine performance without compromising safety or reliability.

Unlike conventional tuners, the Derringer actively monitors multiple engine parameters in real-time via OBD-II connectivity, allowing it to dynamically adjust calibrations based on throttle position, rpm, vehicle speed, air-fuel ratio, knock detection, coolant temperature, and exhaust gas temperature. This intelligent approach ensures maximum safe power output tailored to your driving conditions.

Key Features:

The Derringer Tuner combines cutting-edge technology with user-friendly control, offering six adjustable power levels that can be changed on-the-fly using the Banks iDash interface. Whether you need a mild boost for daily driving or maximum performance for spirited runs, the Derringer adapts seamlessly.

• Six power levels adjustable in real-time via iDash, from work-oriented mid-range tuning to best-in-class performance
• Up to +40 horsepower and +63 lb-ft of torque gains, improving 0-100 km/h acceleration by up to 4 seconds
• Dyno-calibrated tuning that uses multiple engine data inputs for precise, real-time optimization
• ActiveSafety health monitoring circuitry checks system status 100 times per second, instantly bypassing the tuner and reverting to stock settings if any issue is detected
• TransCommand transmission protection ensures safe shifting and transmission longevity
• Automatic power adjustment based on coolant temperature and knock detection to prevent engine damage
• Compact, discreet housing designed for easy installation and concealment
• Seamless integration with Banks iDash DataMonster, SuperGauge, and PedalMonster throttle booster for comprehensive vehicle monitoring and control
• Firmware updates via microSD card through the iDash system keep your tuner current with the latest calibrations
• Compatible with a wide range of Jeep Grand Cherokee and Ram 1500 trims including High Altitude, Limited, Overland, Summit, Trailhawk, Big Horn, Laramie, and more

Construction & Design:

The Derringer Tuner is engineered with durability and precision in mind. Its electronics are housed in a compact, rugged enclosure designed to withstand the harsh conditions of under-hood environments. The tuner connects inline with your vehicle’s engine sensors and diagnostic bus, ensuring seamless communication with the engine control module (ECM). This robust design enables the Derringer to perform continuous real-time adjustments while maintaining system integrity and reliability.

Performance & Sound

By optimizing fuel delivery, timing, and boost parameters, the Derringer significantly enhances engine torque and horsepower throughout the rpm range. Drivers will experience improved throttle response, quicker acceleration, and stronger pulling power, especially when towing or hauling heavy loads. While the tuner does not alter exhaust sound directly, the increased engine efficiency and power output contribute to a more confident and capable driving experience.

Installation & Fitment:

Installation of the Banks Derringer Tuner is straightforward and requires no permanent modifications to your vehicle. The tuner connects inline with existing engine sensors and plugs into the OBD-II diagnostic port. For full functionality, the Derringer requires the Banks iDash interface (sold separately) for programming, monitoring, and adjusting power levels. The tuner is compatible with Jeep Grand Cherokee and Ram 1500 models equipped with the 3.0L diesel engine from 2011 to 2021 (Ram 1500 fitment through 2018).
