Computer Tuning Process

This software is only compatible with Windows PC/Laptop.
ALWAYS use a battery charger when you are installing the tune.

You must first install the client software on your computer. Here is the download link. There should also have been a little pamphlet in the package with this link as well.

Once installed, connect the programmer to your computer and run the software. It will make sure that the device is up to date. Once that is done, you can connect it to your vehicle to ID the car. The handheld will not work unless it is properly updated. Once the vehicle has been ID'ed you will connect it back to your computer so the ID information can be copied and supplied to us to enable us to make a file for your car.

Here are the instructions for pairing the device to your vehicle

1. Plug the OBDII accessory to the vehicle and the handheld.
2. Turn the key to position 2. On vehicles with push to start, typically it takes two presses of the start button WITH FOOT OFF THE BRAKE. Newer BMW’s require three quick presses. The dash/gauge cluster will light up and the check engine light should be on.
3. The handheld screen will light up and show the main menu.
4. Click on the Work tab.
5. Click on the PRT Identify tab.
6. Follow the screen prompts. After a while, another menu will appear.
7. Click on the ID tab. Follow the screen prompts until it tells you the process is complete. Some vehicles require saving of the ECU Coding. If your vehicle is one of them, the handheld will prompt you to do so and provide instructions
8. You may now turn off your car.
9. Connect the handheld to the laptop/desktop.
10. Open the MyGenius software, this time all the tabs should light up.
11. Select the Download From MyGenius tab.
12. Select your stock file.
13. Save the file to your desktop and please put your name in the beginning of the file name so that it looks like this: John Doe MYGFILE.fpf
14. Close the program.
15. Email the file to tuning@weistec.com and list out any modifications that are installed on the vehicle so that we can start making the tune file.

Please note, leaving out modifications or using a name that does not match the order will cause delays.

We do our best to get files back to you as quickly as possible. If a file is sent during Weistec business hours (8am to 5pm Pacific Time Monday through Friday), in most cases a tuned file is sent back within 2 hours. In some cases, in under 30 minutes. There are certain situations where an original file for your vehicle is not readily available. In these cases, you will be notified of potential delays.

Once you receive your tune file via email, save it to your desktop. It contains both the tune file and the original file. The file is encrypted and cannot be opened.

1. Connect the handheld to the laptop/desktop.
