See how easy it is to use the TGT Flash device on your vehicle, by following the steps below
Please note. We do recommend that you attach a Battery Support Unit (BSU) to the vehicle, to ensure it has enough power throughout the entire remapping process. Click here to download a PDF copy of these instructions.
On a Windows based PC or Laptop, open a web browser and go to www.tgtflash.co.uk/downloads to download the TGT Flash software. Double click the downloaded ‘.exe’ file and run through the steps to install it to your computer. If prompted, we recommend saving a shortcut to your desktop.
Once installed, open the program by double clicking the desktop icon. Plug in the TGT Flash device, using the supplied USB cable. The software will recognise your device and perform any updates required. Once completed, close the program window and unplug the device. You are now ready to use the TGT Flash device on your vehicle.
On completion, the next screen will confirm there is no stock file on the device. Click Yes to read the ECU.
The TGT Flash will prompt you once the read is complete. Unplug the device (which now includes your read file) from your vehicle. NB. The device only takes a copy of the original file and the vehicle can be driven as normal after this stage.
Connect the device to to your computer using the enclosed USB cable. Open the TGT Flash Software and click on Download Data. The software will read and download the data file from the TGT Flash device, prompting you to choose a location to save the file.
File turnaround time is typically 1 hour in our regular hours of 09:00-18:00, Monday to Friday, 9:00 – 13:00 Saturdays.
Your file will be modified by our in-house tuning team, using the vehicle information provided, the type of remap requested (Performance/Economy/Blend) as well as any additional requirements and emailed back to you (using the address given) once complete (make a note of the filename).
Your modified file will be sent to the email address stated on the form. Save it to your desktop or suitable location. With the device plugged into your computer, open the TGT Flash software and click on Upload Data. Locate the saved file and click Start to transfer it to the device. Once the upload completes, you can now return to your vehicle to transfer the file.
To add the file to your vehicle, plug the TGT Flash back in to the OBD port and select the “Tuning” button once again.
The device will ask you to confirm that you wish to go ahead with writing the file. Click Yes to proceed with the transfer.
Your file will now be transferred to the vehicle. This can take a number of minutes, so please be patient and ensure the vehicle remains with the ignition on during the entire process. A progress bar will display, giving an indication of the amount of information left to be transferred to the vehicle.
Once complete, you will be presented with a screen confirming the completion and asking you to switch off your ignition and disconnect the TGT Flash.
Your TGT Flash device can store up to 5 files for the car the tool is locked to: so you can easily have 4 maps written for the same vehicle. For example you could have the following stored on your device:
- 1 x stock file for warranty/dealer or diagnostic purposes
- 1 x Economy File (Modified)
- 1 x Blend File (Modified)
- 1 x Performance File (Modified)
