Knowledge ECU TCU CPC 9G

Почему ECU / TCU / CPC нужно проверять вместе

В современных Mercedes / AMG платформах нужная логика может находиться в ECU, TCU, CPC или распределяться между ними.

Control Split

Project review starts from control responsibility before changing numbers.

ECU

  • Driver demand, boost, fuel, ignition and protection.
  • Reviewed against logs and target use.
  • Must match TCU / CPC torque logic.

TCU

  • Shift logic, torque handoff, launch and 9G behavior.
  • Neutral RPM may be TCU-side.
  • ECU-only changes may not solve the target.

CPC

  • Mercedes 2019+ torque, Vmax and CPC_NG coordination.
  • Gen1 / Gen2 / Gen3 path must be identified.
  • Treated as complete vehicle strategy.
