Quick Start Guide
From download to your first coding change
Everything a new user needs, step by step. Download this guide as a PDF. Version 1.2 · esysmax.com
1. What you need
- A Windows 10 or 11 PC (64-bit) with internet at least once a week.
- BMW E-Sys with PSdZData, installed on that PC (not included with E-Sys MAX).
- An ENET cable to the car, and a battery charger connected to the car while you code.
2. Install
- Download the installer from esysmax.com/download and run it. The installer shows the Terms; accept them to continue.
- Open E-Sys MAX from the Start menu. The first time, read the short "Terms and safety" summary and accept it.
- The launcher lists the E-Sys versions it found on your PC.
3. Try it free for 3 days
- In the launcher open Help > Enter licence and press Start the free 3-day trial. No card needed.
- The launcher shows an orange FREE TRIAL badge with the days left.
- The trial works on one car: the first car you connect becomes the trial car.
4. Buy a licence (2 minutes)
- In the launcher open Help > Enter licence and press Buy by card. Your browser opens esysmax.com/buy with your PC ID already filled in.
- Choose 1 year ($59) or Lifetime ($99), tick the three boxes and press Pay by card. Payment is handled securely by Stripe.
- Right after paying, the page shows your licence. Press Copy licence.
- Back in the launcher: Help > Enter licence, paste it, press Activate. Done.
Prefer Telegram? Press Get a licence on Telegram instead: @EsysMaxbot takes your order there. A licence you get in Telegram arrives by itself: just restart E-Sys MAX or press Refresh (top right). Nothing to copy.
5. Your first session
- Connect the charger and the ENET cable. Press play on your E-Sys version in the launcher: E-Sys opens with E-Sys MAX inside.
- Connect to the car in E-Sys, then make a full backup first: E-Sys MAX > Full backup of the car.
- Read the coding data and open a module in the FDL-Editor. The E-Sys MAX panel shows every setting in English and What can I code? lists ready-made changes for your car.
- Check every change before you code it. When in doubt, don't.
6. Useful tools
- Search the car: find any setting in every module by name.
- Coding history: see exactly what changed, and open an older version to put it back.
- Fault scan: read and clear the fault memory of every module.
- Car report (PDF): model, options, modules, changes and faults in one document.
7. Your licence
- One licence works on one PC. A Windows reinstall, new SSD or more RAM keep it.
- E-Sys MAX checks the licence online at least every 7 days and works offline in between.
- New laptop? In the launcher on the new PC: Help > Enter licence > Get a licence on Telegram > Move my licence to this PC.
- Lost your licence text after a reinstall? Use esysmax.com/licence with your order e-mail and PC ID.
8. Safety and legal
Vehicle coding is at your own risk: it can damage control units, change safety systems and make a car illegal to drive. Back up first, keep a charger connected, and only code changes that are legal where the car is used. E-Sys MAX is not affiliated with BMW AG.
