Phase 1: Purchasing

When purchasing a remote tuning kit, you'll select from several options:

1. ECU License

• What is an ECU License?

  • Your ECU (Engine Control Unit) manages your engine. To tune your vehicle using ECUTEK software, your ECU needs a digital license.

• Do I need a license?

  • If your car has never been tuned with ECUTEK: YES.

  • If your car is already ECUTEK tuned: NO.

• Important Notes:

  • Licenses are a one-time purchase, permanently linked to your ECU.

  • Previously used DESKEY licenses cannot be transferred.

2. Bluetooth Connect Kit

• What is this?

  • A small module (green or black) that plugs into your vehicle’s OBD2 port.

  • Required for remotely uploading tunes and sending datalogs via the ECUTEK CONNECT app.

• Do I need one?

  • YES, if you do not already own one.

  • NO, if you already own one (can be shared among multiple vehicles).

• Warranty Note:

  • Used connect kits not purchased from MIGTUNED won't be covered under warranty.

3. Tune Add-Ons (Optional)

• Launch Control: Custom feature for enhanced starts.

• Flex Fuel Option: Requires installed Flex Fuel kit and aftermarket low-pressure fuel pump.

• Aftermarket Parts: Only select if installed (injectors, turbochargers, etc.).

​

Phase 2: Setup (Important Timing Information)

Once you receive your kit, immediate setup is required:

• Base Map Setup: Must be completed within 30 days of delivery.

• Tuning Period: Must begin within 30 days of Base Map setup and completed within 30 days of the first datalog.

• Rescheduling Fee: A Tune Update will be required for any mod changes that require large adjustments during the tuning process or if the tuning timeline is surpassed - tuner has right to extend time limits due to different situations, because you went on an extended vacation is NOT a credible excuse.

Setup Steps

ECUTEK PhoneFlash Initial Setup

Before receiving your BASEMAP, complete the following:

1. Download ECUTEK CONNECT app.

2. Install CONNECT module in OBD2 port.

3. In app, set tuner to MIGTUNED and send vehicle info.

4. Email the following information to MIG@MIGTUNED.COM:

   • Order Number

   • Vehicle type (AWD/RWD or Z)

   • Fuel octane (91 or 93)

   • Full modification list (accurate details required)

   • Transmission type (if applicable)

   • Race tune or Same Day Tuning requests (optional)

Important: Changes in mods after BASEMAP creation incur a $250 retune fee.

Important Reminders

• BASEMAP is safe and extensively tested but does not guarantee no failures.

• Modifying your vehicle increases risk of failure; ensure vehicle condition is optimal.

• Communication and careful following of instructions ensure the fastest and safest tuning experience.

Phase 3: Tuning

After the setup:

ECU Programming Requirements

• Battery Voltage: Must remain above 12 volts; a battery charger (not a jump pack) is required.

• Accessories: Turn off ALL accessories and aftermarket equipment during ECU programming.

• Hazards On: Use hazard lights during initial ECU flash to prevent vehicle shutdown.

ECU Flashing Steps

1. Engage the e-brake fully.

2. Enter ACCESSORY POWER mode (press start button twice, foot off brake).

3. Open ECUTEK app, navigate to "Program ECU," and select "BASEMAP."

4. Follow app prompts. Successful programming is indicated by a smiley face and confirmation message.

 

Troubleshooting Failed Flashes

• If ECU programming fails:

  • Attach battery charger.

  • Flash "STOCK" file first to recover.

  • Retry flashing "BASEMAP."

Note: Random ECU codes ("ghost" codes) are normal during tuning and can be cleared after completion.

Initial Datalogging

• Warm up your car fully (coolant at 185°F or above).

• Take an idle datalog to verify correct setup.

• MIGTUNED will confirm or request corrections via email.

 

Ongoing Tuning Steps

• You’ll receive detailed email instructions after each datalog submission.

• Each submission will receive feedback and a revised tune.

• Pump Gas Map/Flex Fuel Map: Indicates your car is safe to drive aggressively (not final).

• Final Tune: You will receive a file labeled "MIGTUNED" upon completion.

• ​

Phase 4: Datalogging & Communication

How to Datalog

1. Open ECUTEK App > My Car > Data Logging.

2. Select correct datalog profile (ST_Q_BASIC, etc.).

3. Press START to begin logging, STOP to end.

4. Send datalog via ECUTEK App: My Files > Data logs > "SEND TO MIGTUNED."

• Response Time: Within 4-8 business hours.
