xHP uses user-accounts to save all data (vehicles, Custom - settings, licenses) across devices. You are required to create a Login for this. Do so in the sidebar-menu. You have 2 options for that:

• Create a Login manually within xHP

• 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 e-Mail in the background to identify the customers account.

Customers before April 2020: Existing customers are required to use the same email as in Google Play to re-gain access to previously bought items. For instance if your Google Play e-Mail was xyz@gmail.com you can either create an account manually with xyz@gmail.com or use one of the Social-Logins with the same email to re-gain access. It’s not important what option you chose, it’s only important that you use the same e-mail!

Once you are logged in, the app will show the car-list on the “my cars” page, which acts as the main screen. On the top left, you have access to the side bar menu which lets you access all generic functions, not directly related to a certain vehicle (Manual, FAQ, Connect Guide, Support Check, read fault codes, or read adaption etc.).

For all flash operations, either click “Connect” or manually select a vehicle. You can find more Information regarding flashing here.

Licenses and Map-Packs are to be bought in our web shop. Once you completed your purchase, you will receive one or more voucher codes through your email, which can be redeemed inside xHP app.

To redeem a code, you need to connect & save your vehicle first. Please see here on how to do that. Once your car is saved, you will find it on the “my cars” page of xHP. After opening the car, you will see 2 Buttons “Flash License” and “OTS Map Bundle”, which show you the current status. Just tap a button and enter the received voucher code to map this item to your car. Please double-check, that you have selected the correct vehicle and that your are logged in to the correct email account.

xHP will flash the calibration section of your transmission controller with the chosen calibration file. xHP will calculate and display the remaining time during the whole procedure. The flash process is designed to be failsafe and will automatically correct small errors or error prone connections, to a certain degree. However, if a flash fails, you can just start over. xHP is designed to keep your Transmission controller safe in every step of the process. Don’t worry, if your car shows various fault messages during the flash process, as this is perfectly normal. All errors will be cleared after the flash procedure has finished. When the flash has finished, the App prompts you, to switch off your Ignition and let your car sit for a few seconds on 6- Speed vehicles.

For an error-free flash procedure and to put as little load as necessary on your battery, please pay attention to Chapter 3 before flashing your vehicle!

Open your car and click the “Flash” on the bottom right of your screen. Select Flash from the Pop-Up Menu and click the File-Symbol on the top right on the next screen. This will open a file browser to select your custom map. Before proceeding to flash, xHP will carry out extensive sanity checks on your custom calibration. If xHP reports a bad file you possibly edited a restricted section in your file. (e.g. Program part, Project numbers etc.) After completing the sanity check, xHP will flash the calibration section of your Transmission controller with your custom calibration file and calculate all checksums and RSA corrections on the fly.
