What the filename indicates

An engine control module manages engine operation using sensor inputs and software calibrations. Depending on the application, those calibrations can affect functions such as fuel delivery, ignition timing and emissions control. These are general controller responsibilities, not confirmed changes made by this particular file.

The filename includes the labels TUN and E2, but the catalog entry does not define them. They do not, by themselves, establish a specific modification, emissions function or compatibility with a particular Toyota or Lexus model.
