ECU Data Storage

Hello,

Does the ECU store any data specific to engine performance after shut down (i.e. misfire count, flkc, etc.) that is used later down the road if these counts surpass the designated threshold to trigger CELs? Obviously, after a reflash these things are reset.

Any positive feedback would be appreciated.

Thank you
