A Tuner Above The Rest

Experience huge gains in torque and power gains across the full operating rpm range, starting right off idle and marching to the shift point in each gear. Derringer actively and safely optimizes our dyno tuned calibrations in real-time thanks to its OBD-II connectivity.
2D Chart Showing Banks Tuner Speed Difference vs Stock
With access to rich data, the Derringer adapts using multiple data inputs, such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, to maximize power delivery and consistency in all driving conditions. Derringers electronics are enclosed in an easily concealed compact housing and integrates with other existing Banks electronics such as the iDash or PedalMonster.

Choose Your Power

Derringer has 6 levels, adjustable on-the-fly using the iDash.
Level 3 is designed for work use and has a great mid-range feel. When running Level 3 with a loaded truck and/or pulling a trailer, your on-ramp merging speeds and passing times greatly improve.
Level 6 produces best-in-class performance and passing power when you need it most, with a huge gain of 57 extra horses and 73 additional lb/ft of torque.

Tuned Safe

ActiveSafety® health monitoring circuitry keeps an eye on the vehicle and the module itself 100 times a second.
If an issue is detected, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power.
The Derringer auto-adjusts power if knock occurs due to bad fuel, and advanced coolant temp monitoring prevents power addition when the engine is too cold or overheated, preventing damage.

Banks vs The Competition

The Derringer is the only tuner that utilizes your truck's ECM to make intelligent calculations. Utilizing the power of OBD-II, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level. The Derringer calibration continuously adjusts to provide peak performance under every driving condition.
The other guys claim big numbers on paper but simply don't deliver in the real world under steady-state conditions! We tested every other tuner on the same dyno, same day, same weather conditions, and with the same technician.

AutoRate® Dynamic Tuning

• Exhaust Gas Temperature (EGT) — Monitors EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
• Altitude compensation — Senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.
• Diesel Particulate Filter (DPF) Regen — Monitors your DPF regen status to ensure the process completes successfully.
• Accelerator Pedal Monitoring — Rolls in additional power progressively, optimizing for both part-throttle fuel economy and max power when you ask for it.
• Full Power Timer — Allows for 30 seconds of wide-open throttle before transitioning to the recommended power level for sustained tow/haul.
Derringer Wiring Diagram Example
• Coolant Temperature Monitoring — Maintains safe power based on coolant temp.
  • • During warmup, no power is added below 120° F
  • • Power ramps in & fully available above 150° F
  • • If the coolant overheats for any reason, the Derringer starts removing its power at 230° F
  • • Additional power is totally removed if you exceed 240° F

TransCommand® Active Transmission Safety System

The Derringer is calibrated to modulate power during shifting while ramping up hydraulic pressure for better engagement. Competitors lack OBD-II data and always add power at wide-open throttle causing excessive transmission, clutch, and torque converter slip and damage.
• Intelligent Shift Tuning — Senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.
• Boost and Fuel by Gear — Monitors your DPF regen status to ensure the process completes successfully.
• Accelerator Pedal Monitoring — Rolls in additional power progressively, optimizing for both part-throttle fuel economy and max power when you ask for it.
• Tuned Hydraulic Pressure — Allows for 30 seconds of wide-open throttle before transitioning to the recommended power level for sustained tow/haul.
8 Speed ZF transmission
• Torque Converter Clutch (TCC) Monitoring — Maintains safe power based on coolant temp.
  • • Shift signal is optimized for the power level protecting the transmission, increasing shift speed, and avoiding ECM power derates.
  • • Calibration is tuned for optimum traction and performance providing the right firmness of shift automatically.
  • • Ramps hydraulic pressure faster than stock, maintaining engagement as power is added safely within factory limits.
  • • Adjusts TCC slip to safe levels, lowering fluid temperature, and preventing extended wear.
• Transmission Slip Monitoring - Light throttle shifts remain smooth and firm, full-throttle shifts are solid and decisive.
  • This reduction in slip time also improves acceleration performance, an added benefit!

ActiveSafety® Health Monitoring

The Derringer is the only tuner available that includes Active Safety® health monitoring circuitry.
Internal diagnostics check system 100 times per second.
Checks MAP and FRP signals and monitors CPU activity
Activates in event of failure or loss of 12V power
Bypass relays smoothly return stock power with no loss of power or "Limp Home" Mode.
