HOW TO LOAD A TUNE FILE TO YOUR SCT DEVICE

If you bought your SCT device separately from the VMP custom tune, your tune file will be sent to you via email. The tune file will need to be loaded to your SCT device before it can be loaded to your vehicle.
You can load your tune file to your SCT device by:

  1. Download and save the .CEF tune file from the email chain that you have with your calibrator

  2. Connect the SCT device to your computer using the provided USB cable
    *Note, other cables can be used but they must be a data cable capable of transferring files - not just charging*

  3. Open the SCT Device Updater Program

  4. Select "Load Custom Tune File" from the menu of the Device Updater Program.

  5. Click "Browse" from the top right corner of the program

  6. Navigate to the location where you've saved .CEF tune file, and click "Open"

    • You will see the name of the file appear under the "Available Tunes" list

  7. Click the >> Add to Device button

    • You will see the name of the file appear under the "On Device" list

  8. Click "Program" to begin loading the file to your device

  9. Once complete, you can now load the tune file to your vehicle

HOW TO LOAD A TUNE FILE TO YOUR VEHICLE

If you bought your SCT device from VMP in the same order as your custom tune, your tune file may have been loaded to your SCT device before it had shipped out.
You can load the tune file directly to your vehicle by:

  1. Plug SCT device into the OBD2 port of the vehicle using the OBD2 cable provided

  2. Turn the key to the ON position. Do not start the engine

  3. Select "PROGRAM VEHICLE" on the main menu of the SCT device

  4. Read and follow the prompts on the screen

  5. Navigate down to highlight and select the VMP Tune File

    • ** It is important that you flash the VMP custom tune file and not the preloaded tunes that come in the SCT device.
      **Your VMP custom tune will be displayed in your device with the following naming format: Fuel Octane VMP MM/DD/YYYY       EXAMPLE: 93 VMP 01/01/0101

  6. Click the right arrow on the device to highlight and select the "Approve" option

  7. Confirm the information on the screen reflects the VMP tune, and select "Continue"

  8. Continue to follow the prompts on the screen until the screen displays "DOWNLOAD COMPLETE"

  9. Turn the car off, and allow the ECU to completely power down before starting the vehicle.

Datalogging your vehicle allows your tuner to see ECU parameters in real time and make tuning adjustments accordingly.
A good datalog will help your tuner address concerns and verify proper vehicle operation.
The following is IMPORTANT when datalogging:

  • Using the necessary parameters

    • This is CRUCIAL when addressing concerns. VMP offers configuration files that will layout the needed parameters for many vehicle platforms.

  • Preferred naming convention of datalog file
    Please name your file with this naming convention:

      • LAST NAME - FUEL BEING USED - TYPE OF LOG - D ATE - SCT DEVICE SERIAL NUMBER.CSV
        Example) Smith-93Octane-IdleSlowRev-01012020-X4111222333.CSV

  • International Customers
    Laptops must have the Time & Language settings set to certain configuration in order for us to be able to open / review datalogs

      • Country/Region should be set to "United States"

      • Regional Format should be set to "English (United States)"

      • Time Zone should be set to "Eastern Time (US & Canada)"

      • Language should be set to "English (United States)"

  • Important Notes:

    • Please have gone through at least (2) consecutive tanks of one type of fuel before logging

    • Please turn off the air conditioning and defrost before starting your recording.

LIVELINK - STEP BY STEP DATALOGGING INSTRUCTIONS THROUGH A LAPTOP

What you will need:

  • Windows Laptop

  • SCT Livelink GENII Datalogging Software : Click HERE to download Livelink

  • SCT Device Updater Software : Click HERE to download Device Updater

STEP 1) Downloading the SCT datalogging software and the VMP configuration (.cf4) file - Video Time Stamp 0:29

STEP 2) Connecting the SCT device cables - Video Time Stamp 0:56

Open the Livelink datalogging software. Plug the Micro USB cable into the laptop and the bottom of the SCT device, and the OBD2 cable into the OBD2 port and the top of the SCT device.

STEP 3) Checking Device Communications - Video Time Stamp 1:16

Start the vehicle's engine, and click the Comm button located in the Settings menu at the top of the screen.

Once on the Communications screen, click the Check Communication button.

* If the device and vehicle do not communicate, disconnect all the cables and reconnect. Verify that you're using the USB cable that came with the SCT device. *

STEP 4) Loading the configuration (.cf4) file - Video Time Stamp 1:33

Once communication is established, click the Load Config at the top in the Chart Gauges menu.

STEP 5) Starting the datalog recording - Video Time Stamp 1:46

Once the vehicle is up to operating temperature, click the button that is shaped like an SCT device with a green circle on it. It is located on the top left of the screen.

Step 6) Recording the requested datalogs - Video Time Stamp 2:10

Your calibrator will request datalogs based on the conditions they are wanting to see.

Types of Datalogs:

Please perform ONLY the datalogs requested by your tuner - below are examples of the datalogs you may be requested to perform.

  • Idle / Slow Rev Datalog:

Allow the vehicle to get up to operating temperature. The vehicle should idling in neutral/park for a few minutes before this log is performed.
Start the datalog and allow the vehicle to idle for 30 seconds, then slowly rev the vehicle up to ~100 RPM before redline, and then let off the pedal to allow the vehicle to return to idle.

The rev should be a smooth transition, with steady pedal input all the through the RPM range before letting off the pedal to return to idle.

  • WOT Datalog: * Please do not perform WOT datalogs unless advised to do so.**

This datalog should capture a WOT ( W ide O pen T hrottle) pull. This should be done in a gear that will not break traction. The pedal should be completely to the floor from 2,500 RPM to 6,000 RPM. We do not recommend starting pulls lower than 2,500 RPM.

  • Cold Start Datalog: *These logs are not necessary, unless requested by calibrator*

This datalog should capture the cold start taking place. Turn the key to the ON position, but do not start the engine. Start the datalog recording, and then start the engine. The datalog can be stopped after ~3 minutes of run time.

STEP 7) Stopping the recording and saving the datalog (.csv) file - Video Time Stamp 2:57

Click the button shaped like a device with the red square on it. It is located next to the start datalogging button

Save the datalog by clicking the Save ALL button in the datalog menu.

Please save the file with the preferred naming convention.

​

STEP 8) Sending the datalog (.csv) file to your calibrator - Video Time Stamp 3:31

Send the datalog file as a reply to the email chain with your calibrator.

HOW TO LOAD CONFIGURATION FILE TO SCT DEVICE

You are able to datalog with the device, but we do not recommend datalogging with a device due to the lag in the data - the device does not have the processing power that the laptop has. This may hinder your tuner from being able to review the logs efficiently.
