💡 Why Accurate Injector Data Matters

Not all ECUs are created equal — and when it comes to dialing in fuel injectors, especially with factory engine control units, the software formatting and units of measurement can vary depending on how the original engineer designed the system.

Unfortunately, some injector suppliers simply pull random injectors from a bin and provide only an average flow rating — or no individual test data at all. This leads to inconsistency, poor tuning results, and unreliable engine performance.

ECU tuning software such as HP Tuners, SCT, Diablosport, EFILive, COBB, and Holley EFI each require data formatted to match the factory ECU’s original calibration structure. That’s why accurate, injector-specific flow data is critical for proper tuning and seamless ECU integration.

Precision injector data = smoother tuning, better drivability, and true performance consistency.

⚙️ Precision Flow Testing & Data Processing

We flow-test each injector on a laboratory-grade flow bench equipped with precision metering to ensure highly accurate results.
The collected data files are then uploaded to our proprietary processing system, along with key injector details for analysis.

All calculations are performed by a professional calibration engineer with real-world experience in OEM and emissions-compliant applications, ensuring every dataset is formatted correctly and ready for immediate use.

Accurate testing, expert validation — injector data you can trust.

🧠 The Importance of Accurate Injector Data

Proper injector data is essential for allowing the ECU to precisely control fuel delivery.
Incorrect or incomplete data can leave you chasing tuning issues and struggling to get the engine to respond properly.
This often leads to drivability problems, torque management errors, poor fuel economy, and overall inconsistent performance.

The right injector data means smoother tuning, better control, and reliable results.

📦 Injector Data Collection Requirements

To generate accurate injector characterization data, you’ll need to send us a matching set of injectors for testing.
We require a minimum of 4 matching injectors per set (up to a maximum of 8).

Our software compiles results from testing no fewer than four injectors at a time to ensure consistent and statistically valid data.
Once processing is complete, we’ll email you a comprehensive data package in nine ECU formats:

GM, Ford, Dodge, Honda, Nissan, Mitsubishi, Subaru, Bosch, and Universal Aftermarket ECU (Holley/MS3).

Precision-tested. Professionally formatted. Ready for seamless ECU integration.

💡 Supported Injector Types

We test and provide data for Top-Feed, High-Impedance Port Injectors only.
Validated flow range: 2–38 g/s (≈ 15.9–301.6 lb/hr).

🚫 Not Supported:

GDI / Direct-Injection injectors
Low-impedance injectors

💰 Injector Data Service — $250 per Set

The cost for injector data collection is $250 per set, plus return shipping.
Rush orders are available upon request for an additional fee.

📦 How the Process Works:

Box up and send your injectors to us.
Fill out the Customer Sheet on our Home Page and select “Other.”
- In the notes section, write “DATA NEEDED!”

Include the completed sheet with your injectors in the package.
Be sure to include a valid email address for data delivery.
- Alternatively, you may provide a USB drive, and we’ll load the data for you.

⚠️ Injectors must be clean (“Ready to Run”) before testing.
Dirty injectors will produce inaccurate data and must first go through our Clean & Flow Service at an additional cost.
