Key Features & Highlights

EV6 Connectors: Pre-wired with four EV6-style fuel injector connectors (the standard used by Injector Dynamics and most popular aftermarket injectors).
Custom Damond Spec PnP Harness: Designed from the ground up to our exact specifications—labeled, pre-wired, and built specifically for MZR DISI and Ford EcoBoost platforms.
Pre-Flashed With Firmware Out-of-the-Box: Unlike off-the-shelf Microsquirts that ship without firmware, every Damond controller comes pre-flashed with active firmware before leaving our shop, ready to put a tune on.
Direct USB Tuning Cable Included: Includes our custom-built cable that bridges USB straight to the harness's 2.5mm TRS connector—no daisy-chaining multiple adapters just to talk to the ECU like off-the-shelf Microsquirts.
Direct-Fit Mounting on Damond Battery Trays: Bolt-on compatibility with Damond Motorsports battery trays for a clean, OEM-style engine bay setup.
Base Setup Maps Included: Baseline configuration files are available to give your tuner a quick, hassle-free starting point.

Simple, 4-Point Signal & Power Hookup

No tapping into dozens of obscure wires. Beyond plugging in your injectors, the harness only requires four basic connections to get up and running:

12V Power: Cleanly tapped via the included add-a-fuse.
Engine Ground: Critical for signal noise isolation (should be grounded directly to the engine block/head, not the chassis).
Ignition Signal: Picked up from any single cylinder ignition coil with a PnP, removable harness (cylinder choice does not matter).
Load Signal: Connects to the MAF sensor on Mazdaspeed platforms, or the MAP sensor on Ford EcoBoost platforms, both with a PnP, removable harness.

Built-In Expansion Provision

The breakout harness using a 12-pin Deutsch connector (labeled "SPARE") serves as a pre-wired expansion port for future growth. It houses critical dedicated channels—including sensor ground, 5V reference power, flex-fuel signal, and temperature inputs—making it painless to pin in additional sensors or features down the road without modifying the main harness.

Future Development & Advanced Capabilities

The Microsquirt platform is packed with untapped potential. While the base kit focuses on rock-solid port injection fuel delivery out of the box, we are actively researching and developing expansions using the integrated expansion port.

Note: The potential capabilities below are in testing/development. Unlocking these features in the future will require tune updates, additional sensors pinned into the expansion connector, and an experienced tuner.

Closed-Loop Fueling: Real-time wideband feedback to dynamically adjust port injector pulse widths and maintain target air-fuel ratios under load.
Flex-Fuel Integration: Ethanol content sensor input to automatically scale secondary fueling based on your exact E85 blend.
Electronic Boost Control: Utilizing the controller to manage boost output directly alongside secondary fuel delivery.
Auxiliary Fuel Pump Actuation: Triggering external inline or surge tank fuel pumps dynamically based on load, boost, or RPM thresholds.
Fuel Pressure Monitoring: Tracking secondary rail fuel pressure in real time to fine-tune injection and protect against pressure drops.
Lean-Condition Failsafe Protection: Leveraging closed-loop monitoring and fuel pressure tracking to cut power to the boost solenoid if a lean condition or fuel pressure drop occurs.

Ready to unlock your platform's full fueling potential?

Stop letting the factory direct-injection system hold back your horsepower goals. Upgrade to the Damond PI Aux Fuel Controller Kit today and give your tuner the seamless, reliable port-injection management your build deserves.
