Fab9 Tuning – Quick Guide to Datalogging with ECUTek (NC & ND Miata)

Requirements

• Windows-based laptop with ECUTek ProECU installed

• Fab9 Tuning calibration file (provided by us)

• ECUTek OBD2 interface cable (USB)

• Vehicle with ECU tuned by Fab9

Step 1 – Connect Everything

1. Make sure your laptop is charged or plugged in.

2. Connect the ECUTek cable to your laptop via USB.

3. Plug the other end into your Miata’s OBD2 port (located under the driver’s side dash).

4. Turn the ignition to ON (engine not running).

Step 2 – Open Your Calibration

1. Launch ProECU on your laptop.

2. Go to File → Open Calibration.

3. Select the calibration file that Fab9 Tuning provided.

   • This ensures you’re logging the correct parameters for your tune.

Step 3 – Select Logging Parameters

1. From the top menu, click Tools → Log ECU Data.

2. A live data window will appear.

3. By default MORE than enough parameters will be selected. Select any that your Fab9 tuner has requested. Typical items include:

   • Engine Speed (RPM)

   • Throttle Position

   • Boost Pressure / Manifold Pressure

   • AFR (Air-Fuel Ratio)

   • Knock Retard

   • Ignition Timing

   • Fuel Trims

4. Keep the list focused — too many parameters can slow logging.

Step 4 – Start Logging

1. Start the car, lete idle settle and click the Map Access then Record to file buttons (The loading bar will turn GREEN).

2. Drive the car as instructed by your Fab9 tuner.

   • Non-Turbo Cars: steady cruise, wide-open throttle pulls, or and idle. 10 Minutes is usually plenty of data.

   • Turbocharged Cars: On your first log, it will just be idle. We want to make sure your sensors are configured correctly. Please allow your tuner to respond with further instructions beyond that starting revision.

3. When finished, click Map Access once more.

Step 5 – Save & Submit Your Log

1. Your datalog will be saved by default in your Documents>ECUTEK>Data logs

2. Make sure you're sending the latest data log. It will have the same name as the file you've recorded it with (example: Fab9_Log_3rdGearPull_2025-10-01.csv).

3. Go to the Fab9 Tuning Portal: fab9tuning-help.freshdesk.com

4. Open a Request Ticket, attach your datalog file(s), and include notes (gear used, fuel type, conditions, etc.).

   • This ensures our tuning team can review your data and provide updates quickly.

Tips for Clean Logs

• Perform logs on a safe, open road or dyno environment.

• Use 3rd or 4th gear pulls from ~2,000 RPM to redline unless told otherwise.

• Avoid cycling extra accessories (A/C, fans, lights) that could affect results.

• Only log when requested — unnecessary logging can produce massive files.

✅ That’s it! You’ve successfully created and submitted a Fab9 Tuning datalog using ECUTek on your Miata.
