What this does

Stage 1 increases injection and boost via map tweaks — no hardware changes. Typical real-world gain on the Mercedes A 250: +15-25%. Drivetrain stays factory; reverts cleanly with original BIN.

How to apply it

  1. Get a DaVinci Deluxe license (Standard 299€ lifetime, Pro 499€, Monthly 79€, Yearly 790€).
  2. Read the BIN from your Bosch MED17.7.7 via any OBD/bench tool (KESS, Autotuner, FoxFlash, MagicMotorsport).
  3. Open the file in DaVinci Deluxe, toggle Stage 1 Remap, save the patched BIN. Checksum is auto-corrected.
  4. Flash the patched BIN back to the Bosch MED17.7.7. Done.
