Banks Power Derringer 66682 Stops the competition dead in their tracks. 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. Banks 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.
Banks Derringer 66682 has three switched settings: Stock, Plus and Sport. Sport produces Best in Class performance and knocks you back in your seat. The Plus setting is for work use and has a great mid-range feel. When running Plus with a loaded work 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 using B-Bus (Banks Bus) with other devices such as our iDash 1.8 DataMonster or iDash 1.8 SuperGauge. The Derringer connects in line with your truck's engine sensors. But, unlike others, it also connects to the vehicle's OBDII diagnostic bus connector.
A CAN (Controller Area Network) transceiver chip communicates with OBDII or B-Bus allowing our microprocessor to talk with the vehicle. And, 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.
Banks Derringer Tuner 66682 with ActiveSafety, with switch for use with 2017-19 Chevy/GMC 2500/3500 6.6L L5P Duramax Diesel
Test Vehicle: 2017 Chevrolet Silverado 3500 Dually 6.6L Duramax L5P. Factory intake and exhaust. All tests run on the same truck, same day, same conditions. Tested on Mustang DYNO, 10-second sweep.
How the Banks Derringer does what it does, and why.
There’s no easy way to make more power your daily driven Duramax L5P with GM’s ECU and factory turbo, no magic flash or special chip available. We had to go the tuner route, and making an inline tuner for your truck was no easy task. We have almost a thousand man-hours into Derringer development. Fortunately, we’ve been making tuners for 20 years, so we know what we’re doing.
The Banks Derringer is a plug-and-play microcomputer designed for easy installation, it’s enclosed in a compact housing which is easily concealed, and connects to the iDash 1.8 Super Gauge for the ultimate in information and power selection, unlocking three additional power levels.
Unlike the fixed tuning used by others, the Banks Derringer 66682 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.
TransCommand Active Transmission Safety System
In addition to AutoRate Adaptive Tuning, the Banks Derringer utilizes key engine and transmission parameters to enhance shift performance and improve the longevity of your transmission. Because the competitors lack the essential OBD-II data, they always add power at wide open throttle-no matter what!
This can cause excessive transmission slip,torque converter clutch slip and even 170 HP engine derates in order for the transmission to complete the shift. This harms the overall performance and degrades your transmission. The Derringer is meticulously calibrated and extensively tested to properly modulate power during shifting, optimizing performance and safety.
The Derringer is the only tuner on the market to include Active Safety, an active failsafe system that utilizes bypass relays to smoothly transition your vehicle to stock power levels in the event of any trouble signs in the Derringer. The system constantly monitors various parameters at over 50 times a second to ensure that everything is operating as it should.
If any competitive tuners lose power or fail in any way, they will instantly trigger a limp home mode where all power is lost and the vehicle dangerously slows to a crawl. If the same fault condition occurs to the Derringer it will gracefully remove its additional power and return to stock power levels without a hitch.
Additional Features with Banks iDash 1.8
Stock Duramax L5P Turbo Limits
The factory turbo is done at 505 flywheel hp, that’s a gain of 60 horsepower. Above that point, the turbine drive pressure increases dramatically as does EGT and no more boost is available to safely add horsepower. Anyone who claims to deliver more doesn’t understand this engine.
The Banks Derringer 66682 L5P Duramax tuner is the most sophisticated inline tuner available. We hope you have as much fun driving with it as we did making it.
