xHP uses user accounts to store all data (vehicles, custom settings, licenses) across devices. You will need to create an account for this. Do this in the sidebar menu. You have two options:

• Manually create an xHP-specific account

• Use social logins (Google, Facebook, Apple)

This login scheme started with app version 3.0 in March 2020 and the introduction of the iOS version of xHP. With previous versions, the app used the Google Play Store email in the background to identify the customer's account.

Once logged in, the application displays the list of vehicles on the "Overview" page, which acts as the main screen.

At the bottom, you find the menu, which gives you access to all the general functions not directly related to a specific vehicle:

• News - here you find all the latest developments

• Check Support - includes a VIN scanner, for example

• Help - including links to our Tour, FAQ, Manual & Connect guide

• More - with Diagnostics, the “Send Logs” feature, app settings and “About” page.

For all flashing operations, click "CONNECT NEW CAR" or select a vehicle manually.
You can find more information about flashing here.

Flash Combos can be purchased from our website:
Your #1 Source for BMW TCU and AWD Tuning!

Once you have completed your purchase, you will receive one or more voucher codes via email, which you can redeem within the xHP app.

To redeem a code, you must first connect to your vehicle.
You can find out how to do this here.

Once your car appears in the app, it can be found on the xHP "Cars" page.
After opening the car, you will see two buttons marked “redeem” next to the "Flash Combo".
Tap the button and enter the voucher code you received to map that item to your car.

Please check that you have selected the correct car and are logged in to the correct email account.

Once a voucher code has been redeemed, it can no longer be used and cannot be undone.

xHP will flash the calibration section of your transmission controller with the selected calibration file. xHP will calculate and display the remaining time throughout the process.
The flash process is designed to be a failsafe and will automatically correct minor errors or faulty connections to a certain extent.

However, if a flash fails, you can start again.
xHP is designed to keep your transmission controller safe at every process step.
Don't worry if your car displays various error messages during the flash process, as this is perfectly normal. All errors will be cleared when the flash is complete.
When the flash is complete, the app will ask you to turn off your ignition and let your car sit for a few seconds on 6-speed cars.

For an error-free flash procedure and to minimise the load on your battery, please read the How to connect to your car section before flashing your vehicle!

Open your car and click "FLASH THIS CAR" at the bottom of your screen. Click on the "File" symbol above the "Info" buttons of the OTS maps.

This will open a file browser where you can select your 3rd party custom map. Before the flash, xHP will perform extensive health checks on your custom calibration.

If xHP reports an "invalid" file, you may have edited a restricted section of your file (e.g., Program part, Project numbers, etc.).

Once the sanity check is complete, xHP will flash the calibration section of your transmission controller with your custom map file, calculating all checksums and RSA corrections on the fly.

Original xHP Custom Map files purchased from our Your #1 Source for BMW TCU and AWD Tuning!, will be directly visible below the OTS Stages.
