Designation and processor
The Chiptuner-Datenbank control-unit catalogue lists Bosch Motronic M4.6; the processor of its individual hardware revisions has not been verified here.
Application example
An ECU repairer identifies a Kia Sportage 2.0i 4x4 2001–2002 example as M4.6. This is a source-scoped example; match the actual part number before use.
Identification and scope
Record the Bosch and vehicle-manufacturer ECU part numbers, engine code, market, year, hardware and software identity. Identify the processor from the specific unit before relying on its architecture. No pinout, interchangeability or programming procedure is established by a family designation alone.
