Bridge Module for Aftermarket EFI Systems

The BIM-EFI-1 Expansion / Bridge Module for EFI Systems is the next evolution of ECU-to-gauge integration, engineered for builders, tuners, and restorers who want clean installs, accurate data, and future-proof connectivity. Designed by Dakota Digital, this re-engineered interface decodes real-time data from popular aftermarket EFI systems and delivers it directly to your Dakota Digital gauge system—without duplicating sensors, cluttering the engine bay, or compromising reliability.

Whether you’re upgrading a classic muscle car, finishing a pro-touring build, or wiring a modern EFI swap, the BIM-EFI-1 simplifies the job while unlocking a deeper level of engine data on your dash. Add Bluetooth® setup, over-the-air updates, and broad ECU compatibility, and you’ve got a smarter bridge between modern fuel injection and premium digital instrumentation.

See below for the corresponding CAN Bus harness that will be REQUIRED in addition to the BIM-EFI-1 module.

What the BIM-EFI-1 Does (and Why It Matters)

At its core, the BIM-EFI-1 is a CAN bus interface module that listens to your aftermarket EFI ECU, decodes the data it broadcasts, and translates it into signals your Dakota Digital gauges understand. This eliminates the need to install duplicate senders for items like RPM, coolant temperature, or oil pressure—saving time, cost, and potential failure points.

Key benefits at a glance:

• Cleaner installation: Fewer sensors and wires under the hood

• Accurate data: Reads directly from the ECU you trust

• Expanded gauge info: Unlocks additional readings when supported by your ECU

• Future-ready: Bluetooth® programming and over-the-air firmware updates

The result is a streamlined wiring layout and a dashboard that displays the same data your ECU uses to make decisions—no guessing, no redundancy.

Bluetooth® Setup & Over-the-Air Updates

One of the biggest upgrades to the BIM-EFI-1 platform is built-in Bluetooth® technology. Instead of connecting laptops or opening up the dash to change settings, you can configure the module using a compatible smartphone or device.

Bluetooth® advantages include:

• Quick setup and programming from your phone or tablet

• Simple ECU selection and configuration

• Wireless firmware updates to maintain compatibility with EFI manufacturers’ latest software

• No special cables or adapters required

As aftermarket EFI systems evolve, the BIM-EFI-1 evolves with them—ensuring long-term compatibility and protecting your investment.

Seamless Integration with Dakota Digital Gauge Systems

The BIM-EFI-1 is purpose-built to integrate with Dakota Digital’s digital gauge families, including VFD3, VHX, HDX, RTX, and GRFX series. Once connected, your gauges can display a wide range of engine and drivetrain data provided by your EFI system, depending on ECU capability and configuration.

Commonly supported readings include:

• Engine RPM

• Vehicle speed

• Throttle position

• Coolant temperature

• Intake / manifold air temperature

• Fuel level and fuel pressure (where supported)

• Oil pressure and oil temperature (where supported)

• Air/fuel ratio

• MAP / boost

• Transmission temperature

• Ambient air temperature

• Check engine / MIL status

Availability of each parameter depends on the specific EFI system and how it’s programmed, which is why the compatibility chart above is such a valuable reference during planning.

ECU Compatibility That Covers the Big Names

Dakota Digital designed the BIM-EFI-1 to work with many of today’s most popular aftermarket EFI systems. When paired with the required CAN bus harness (sold separately), the module can communicate with a wide range of ECUs used in street, performance, and racing applications.

Supported EFI platforms commonly include:

• Holley® EFI systems (HP, Dominator, Sniper, Terminator, and select early models)

• FAST™ XFI and EZ-EFI systems

• AEM® EFI systems

• MegaSquirt® platforms

• Haltech® systems

• MSD® Atomic EFI

• FuelTech® systems

• MoTeC® ECUs

• And additional aftermarket EFI controllers listed in the compatibility chart

Because EFI manufacturers may add or change CAN data streams over time, Bluetooth® firmware updates ensure the BIM-EFI-1 stays current as software revisions roll out.

Important Fitment & Harness Requirements

The BIM-EFI-1 module requires a corresponding CAN bus harness, which must be purchased separately. The harness selection depends on your specific EFI system and is essential for proper communication between the ECU and the BIM-EFI-1.

Important Note:
For OEM ECUs using J1850 or CAN protocols with a factory OBD-II diagnostic port, this module is not the correct solution. In those cases, refer to the BIM-01-2 OBD-II interface instead.

This distinction is critical when planning your build, especially for late-model engine swaps that retain a factory ECU.

Designed for Professional Builds and DIY Projects Alike

The BIM-EFI-1 is equally at home in a high-end shop build or a well-planned garage project. Dakota Digital’s focus on documentation, modular design, and plug-and-play connectivity means fewer surprises during installation.

Why builders love the BIM-EFI-1:

• Reduces install time compared to traditional sender-based setups

• Minimizes wiring complexity

• Improves serviceability and diagnostics

• Keeps the engine bay clean and professional

• Delivers consistent, ECU-verified data

For show cars, it preserves visual cleanliness. For performance builds, it ensures accuracy. For daily drivers, it improves reliability.

Built to Match Modern EFI Performance

Aftermarket EFI systems generate more data than ever before. The BIM-EFI-1 makes that data usable at a glance, turning your gauge cluster into a real-time command center.

Instead of relying on warning lights or hidden laptop screens, you can monitor critical engine parameters directly from your dash—helping you spot issues early, fine-tune performance, and drive with confidence.

Technical Highlights

• CAN bus decoding interface for aftermarket EFI systems

• Bluetooth® enabled for wireless setup and updates

• Designed for Dakota Digital digital gauge systems

• Eliminates duplicate senders and sensors

• Supports a wide range of engine and drivetrain parameters

• Compact module for easy mounting under dash or behind panels
