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.)
