In-Depth Feature Highlight

Banks Derringer provides six power levels, where Level 3 provides a comfortable work use driving experience and Level 6 has the ability to knock you back in your seat.

OBDII Port Connection

Unlike other tuners in the market, Banks Derringer provides you a simple easy plug and play installation option with the OBDII Port connection.

ActiveSafety® Feature

Derringer is the only tuner on the market to include Active Safety', which is an active failsafe system to smoothly transition your vehicle to stock power levels in the event of any trouble signs in the Derringer.

TransCommand® Active Transmission Safety System

Derringer utilizes key engine and transmission parameters to enhance shift performance and improve the longevity of your transmission. The Derringer is meticulously calibrated and extensively tested to properly modulate power during shifting, optimizing performance and safety.

AutoRate® feature intelligently provides optimum power to the vehicle by reading the vehicle parameters while adjusting fuel and boost dynamically. Other AutoRate features include altitude compensation i.e the Derringer increases boost as ambient air pressure decreases.

What's In The Box

  • Banks iDash unit (Supergauge or DataMonster)
  • 2x Banks Stickers
  • Contact card
  • Instruction manual
  • OBD-II cable
  • Starter cable
  • A packet of zip ties for clean installation

What's the difference between iDash, DataMonster, and Supergauge?

This confused us too. The iDash is the gauge hardware, which comes in two variations: Supergauge and DataMonster. The Supergauge and DataMonster are identical except the DataMonster allows the user to install an SD card to datalog parameters. This is extremely helpful for diagnosing issues, testing performance changes when new parts are installed, etc.

What happened to the switch version of the Derringer?

The switched version is still available, for now. If you are aware of its limitations and MUST have that version because you don't want to use an iDash - Please email us. We will have your order out the door with all our same shipping & warranty benefits. Please be aware Banks Power intends to phase out the switch version in the near future.

Can I do a forced regen with the Derringer?

Yes. The Derringer tuner constantly monitors your regen status and displays them on screen of the iDash, which also allows you to do a forced regen whenever required. However, this function works only for some selected makes and models.

Is this compatible with the new 10 spd transmission?

Yes. Derringer 2020 includes an updated circuit board for supporting the 10-speed transmission.

What if I want to use this with another OBDII-connection product?

You can use the Derringer with another OBDII-connection product by using an Universal OBD-II Splitter.

Does the Derringer read DTC/CEL codes?

No, the Derringer module itself does not. The iDash monitor does read & clear the DTC/CEL codes.
