Banks # 66592-DL is a Derringer Tuner w/iDash 1.8 Data-Logging via Marken Performance that fits 2017+ Chevy/GMC 2500/3500 6.6L L5P yielding up to 61 HP and 112 lb-ft TQ with 6 power levels (when used with iDash). It Interfaces with OBDII Port (On-Board Diagnostics/Information) to communicate directly with the vehicle ECU. The iDash 1.8 Super Gauge, 52mm 2 1/16 Form Factor, 1.8” LCD Display. The electronics are molded into a waterproof connector, which is easily concealed and communicates using B-Bus (Banks Bus) with other devices such as our iDash 1.8 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 our microprocessors to talk with the vehicle. 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. Simple plug and play installation with easy removal for dealer service and no reflash required as it has no traces left in ECU. 

   In addition to AutoRate Adaptive Tuning, the 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 loose 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.
