How Remote Tuning Works on the Kia Stinger and Genesis 3.3T

Remote tuning allows you to flash a custom tune to your Kia Stinger or Genesis 3.3T from anywhere using an EK1 device—no dyno visit or shop appointment required.

Step 1: Patching the ECU

Before you can flash a tune, your ECU needs to be patched. This step unlocks the ECU so it can accept custom files from the EK1 device.

In most cases, the patch for your ECU is already available and provided to you just like a tune file. Flashing it is simple:

Put the patch file in the Maps folder on the provided microSD card.
Insert the provided microSD card into the EK1.
Plug the EK1 into your OBD2 port.
Turn on the car’s power mode (ignition on, engine off, all dash lights visible).
Navigate to: Power Mode > Writing ECU > Select File
Choose the patch file and follow the prompts.

Once patched, your ECU is ready to accept custom tuning files.

🔋 Recommended: Use a battery tender while flashing to prevent voltage drops during the write process.

⚠️ Rare Case: If your ECU has a calibration that isn’t supported yet, you may need to read it using bench cables and submit the file to the EK1 manufacturer. This usually takes 1–2 business days. You can get the bench harness here.

Step 2: Flashing Your Tune

After your ECU is patched, you’re ready to flash your tune.

Put the provided tune file into the Maps folder on the SD card.
Insert the card into the EK1.
Turn on power mode (ignition on, engine off, all dash lights visible).
Go to: Power Mode > Writing ECU > Select File
Select the tune file and let the device flash it.

The EK1 will let you know when the process is complete.

🔋 Recommended: Use a battery tender while flashing to prevent voltage drops during the write process.

Step 3: Data Logging & Revisions

Once your base tune is installed, your tuner will guide you on how to collect data logs. Depending on your tools, this may involve:

Utilizing your PiggyBack for Logging (JB4, ProTuner, etc.)
Logging directly via EK1
Or using a laptop-based logger if needed

Follow your tuner’s instructions carefully—logging the correct parameters under the right conditions is critical for safe adjustments. Based on your logs, you may receive tune revisions or adjustments for any piggyback devices or external boost controllers in your setup.

Each revised file is flashed the same way, using the EK1 and SD card.

Built for Flexibility, Backed by Guidance

Remote tuning with the EK1 gives you the flexibility to flash and revise your tune on your schedule. Whether it’s a stock turbo setup or a full-on build, the process is designed to be safe, repeatable, and backed by real support.
