Banks Power Derringer Tuner - L5P

AutoRate® Dynamic Tuning

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. 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 – 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 your ECM 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.)
