2020-2023 Duramax L5P Derringer Tuner w/ Super Gauge (67102)

Fits

The new Derringer 67102 by Banks Power is hands down the best warranty friendly tuner available for the L5P Duramax. It safely increases your torque and power gains from idle to the shift point. It's unlike your average tuner that adjusts timing and fuel, the Derringer works like your engines ECU and is constantly updating multiple data inputs every second like throttle position, RPM, speed, AFR, knock, and coolant temperature. This is why it can safely optimize and calibrate your tunes to your truck and the conditions you're putting it through, nothing else on the market is capable of that.

Super Gauge vs Data Monster: Super Gauge is your average Derringer Tuner, the main benefit of going with the Data Monster (Part Number: 67102) is getting the Data Logging feature. The Super Gauge is the best option for 90% of users.

Safety

The coolant monitoring prevents power addition when your engine is too cold or too hot, the knock sensor will adjust and pull timing from low-quality fuel. This means the maximum power settings are automatic and based on how the trucks running, similar to how your ECU works from the factory.

Power

Derringer has six switched settings. Level 6 produces Best in Class performance and knocks you back in your seat. The Level 3 setting is for work use and has a 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.

Unlike other tuners that use a fixed flash tune, the Derringer Tuner is constantly adjusting to the conditions to provide peak performance in every unique scenario. By utilizing the OBDII port, the Derringer fine-tunes the power levels on the fly without having to adjust the power levels.

• 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.
• Diesel Particulate Filter (DPF) Regen – The Derringer tuner constantly monitors your DPF regen status and will optimize its calibration to ensure the DPF regen process completes successfully.
• Accelerator Pedal Monitoring – The Derringer senses accelerator pedal position to roll in additional power progressively, optimizing part-throttle fuel economy and giving max power when you ask for it.
• 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 utilizes the 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 derate 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.

• Intelligent Shift Tuning – The transmission shift request signal is monitored to optimize the power level prior to the shift protecting the transmission, increasing shift speed and avoiding ECU power derates.
• Boost and Fuel by Gear – Gear based calibration allows for optimum traction and performance
• Torque Converter Clutch Slip Monitoring – The Derringer adjusts to modulate TCC slip to safe levels.
• Transmission Slip Monitoring – The Derringer adjusts calibration to modulate transmission slip to safe levels

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.

• Internal self-diagnostics checks the health of the system 50 times per second
• Monitors MAP and FRP signals for out of range condition (disconnected or short circuit)
• Watchdog timer constantly monitors CPU activity
• Active safety engages if 12-volt power is lost to the Derringer tuner
