Identification and evidence
The Auto-Remap Toyota ECU archive lists an MP5.3 designation. Its vehicle and hardware coverage require independent verification. Do not assume that M5.3 and MP5.3 denote the same ECU.
Identification and scope
Retain the complete ECU designation, Bosch and vehicle-manufacturer part numbers, engine, vehicle year and market, hardware and software identity. Similar names do not establish shared pin assignments, calibration files or programming procedures. Examples above are source-scoped and are not a complete fitment list.
