T-0133-10-idle750-org was 700at 80c.bin: Idle Calibration
A catalog reference for T-0133-10-idle750-org was 700at 80c.bin and its idle-speed label.
T-0133-10-idle750-org was 700at 80c.bin is a firmware file labeled with an idle-speed change from 700 to 750 rpm at 80°C. In practical terms, that points to a higher engine idle target when the engine is warm, although the filename alone does not establish the full conditions under which the target applies.
What the filename identifies
The label idle750 names a 750 rpm idle value, while was 700at 80c describes the earlier value as 700 rpm at 80°C. The word org appears in the filename, but it does not by itself establish whether the file is a stock original or a modified calibration.
An engine control module normally regulates idle speed by adjusting engine operation to maintain a target as conditions and loads change. This file’s label points to an idle-related calibration, but the identifier does not reliably establish the exact controller, Toyota or Lexus model, or calibration application.
