Specifications

Results 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 is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFR, knock, coolant temperature, and EGT, just like your engine's ECM. It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity. No competitive tuner does that.

Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance. 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 are greatly improved.

The electronics are enclosed in a compact housing which is easily concealed and communicates with other Banks devices such as our iDash DataMonster, iDash SuperGauge, and PedalMonster throttle booster. The Derringer connects in line with your truck's engine sensors. But unlike other tuners, it also connects to the vehicle's OBD-II diagnostic bus.

ActiveSafety health monitoring circuitry keeps an eye on the vehicle and the module itself. It checks its health 100 times a second. If it detects an issue, the Derringer instantly bypasses itself, sets a device diagnostic code, and seamlessly returns the truck to stock power. Plus, Derringer's special coolant temp monitoring prevents power addition when the engine is too cold or overheated. The Derringer also auto-adjusts power if knock occurs due to bad fuel. Maximum safe power is all automatic with a Derringer — you just choose your preferred power level and enjoy the ride.

A Tuner Above The Rest

The Derringer is dyno calibrated to use multiple data inputs such as throttle position, rpm, vehicle speed, AFP, knock, coolant temperature, and EGT, just like your engine's ECM.

It actively and safely optimizes calibrations in real-time thanks to its OBD-II connectivity while providing huge performance gains, all while keeping your factory ECM happy, temperatures under control, and transmission safe.

No competitive tuner does that.


Horsepower Gains & Safety

Derringer has 6 levels, adjustable on-the-fly using the iDash. Level 6 produces best-in-class performance, while Level 3 is for work use with great mid-range feel with a loaded truck and/or pulling a trailer.

Banks ActiveSaftey® features combines mechannical fail-safe measures to revert to stock in the case of failure, while also intelligently adding power based on vehicle operating conditions such as cold or hot coolent tempos or knocking from bad fuel.

The Derringer is the only tuner that actually utilizes your truck’s ECM to make intelligent calculations.


Torque Gains

The other guys claim big numbers on paper but simply don't deliver in the real world! We tested every other tuner on the same dyno, same day, same weather, and same technician. All they do is add fuel with no aditional air.

That’s where all the others fall short, infact power can even be reduced under load as the tuner box and factory ECM fight each other over rising Exhaust Temps and unsafe power delivery.


Get What You Pay For

Dont waste your money on competitive products offering cheap thrills that only dump fuel into the engine with no added air.

Invest in quality backed by engineering. When you compare the power gains per dollar spent, there is no question who offers the highest smile per dollar ratio.

Consistent Power Delivery

The real-world benefits of powerful tuning done safely and reliably really show when you’re hauling a heavy load.

You do not want a cheap tuner that only adds fuel to the engine with no added air. That is just a one-way ticket to soot and high EGTs on your engine.


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 — Shift signal is optimized for the power level protecting the transmission, increasing shift speed, and avoiding ECM power derates.

• Tuned Hydraulic Pressure —Ramps hydraulic pressure faster than stock, maintaining engagement as power is added safely within factory limits.

• Torque Converter Clutch (TCC) Monitoring —Adjusts TCC slip to safe levels, lowering fluid temperature, and preventing extended wear.

  • Calibration is tuned for optimum traction and performance providing the right firmness of shift automatically.

• 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
