Add power and fuel economy to your Duramax with the most trusted name in diesel performance, Banks Power.
Stop the competition dead in their tracks with the Derringer Tuner. Banks delivers 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 and coolant temperature, just like your engine's ECU. Its microprocessor based electronics are able to actively and safely optimize calibrations in real time. No competitive product does that.
Derringer has six switched settings. Level 6 produces Best in Class performance that knocks you back in your seat. The Level 3 setting is for work use and has great mid-range feel. When running Level 3 with a loaded work truck and/or pulling a trailer, your on ramp merging speeds and passing times are greatly improved.
The electronics are molded into a waterproof connector, which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as the iDash Super Gauge/Control Center. The Derringer connects in line with the Throttle Inlet Pressure (TIP) and Manifold Absolute Pressure (MAP) sensors. But, unlike others it also connects to the vehicle's OBDII diagnostic bus connector. A CAN (controller area network) transceiver chip communicates with OBD or B-Bus allowing Banks' microprocessors to talk with the vehicle. On top of that, Derringer's special coolant temp watchdog 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 setting.
The Banks difference when it comes to L5P POWER! - Derringer has 6 power levels, adjustable on-the-fly, with a best gain of +117 hp pushing power well above 520 wheel hp to the road. Plus, the massive increase of +225 lb-ft of torque is situated right in the heart of the power band where you need it most.
How the Derringer does what it does, and why. - There's no easy way to make more power for your daily driven L5P with GM's ECU and factory turbo, no magic flash or special "chip" available. Banks had to go the tuner route, and making an inline tuner for your truck was no easy task. Banks has almost a thousand man-hours into Derringer development. Fortunately, they've been making tuners for 20 years, so it was all in a day's work.
The Derringer is a plug-and-play microcomputer designed for easy installation, it's waterproof for convenient under hood mounting, and connects to the iDash Data Pro Powertrain Information Center for the ultimate in information and power selection, unlocking three additional power levels.
AutoRate - Unlike the fixed tuning used by others, the Derringer calibration is continuously adjusting to provide you the peak possible performance under every driving condition. By utilizing the power of the OBD-II data, the tuner intelligently fine-tunes its calibration on the fly without you having to change its power level.
-
Exhaust Gas Temperature (EGT) - The Derringer senses your engine's EGT and intelligently modulates fueling to maintain a safe maximum EGT, protecting your turbo and engine.
-
Altitude compensation - The Derringer senses ambient air pressure, controlling the turbocharger to maintain added boost and power as altitude increases.
-
Coolant Temperature Monitoring - The Derringer senses coolant temp to control added power. During warmup, no power is added below 120° F, then power is ramped in and fully available above 150° If the coolant overheats for any reason, the Derringer starts removing its power at 230° F and additional power is totally removed if you exceed 240° F.
-
Full Power Timer - If set on Sport level, the Derringer allows for 30 seconds of wide open throttle before transitioning to the recommended power level for sustained tow/haul. (Our research has shown that the stock L5P when at full power will hit 1450° EGT and after a minute or so will pull out fuel to cool things down. So, we do the same thing.)
TransCommand Active Transmission Safety System - In addition to AutoRate Adaptive Tuning, the Derringer High Output is calibrated to modulate power during shifts for better clutch engagement. Thanks to its OBD connectivity, Derringer knows when the GM/Allison 10-speed transmission is shifting gears. It reduces its added power momentarily to allow for a smooth shift. Competitive tuners have no idea or simply ignore when the transmission is shifting and continue to add power, overspeeding the transmission and causing long-term damage.
-
Intelligent Shift Tuning - Gear shifts are optimized for each power level to protect the transmission and increase shift speed while protecting against torque converter and clutch slip.
-
Accelerator Pedal Monitoring - Rolls in additional power progressively, optimizing for both part-throttle fuel economy and maximum power when you want it.
ActiveSafety - Banks combines mechanical fail-safe measures to revert to stock in the event of internal failure while also intelligently adding power based on vehicle operating conditions, such as cold or hot coolant temps or knock from bad fuel.
- Internal self-diagnostics checks health of the system 50 times per second
- Monitors MAP and FRP signals for out of range condition (disconnected or short circuit)
- Bypass relays smoothly return stock power with no loss of power or "Limp Mode"
- Active safety engages if 12-volt power is lost to the Derringer tuner
