    differance on Writing Calibration or Entire

    Hi

    This May be a dumb questions but here it is.

    What Is the differance betwen Write calibration or Entire ?

    My understanding is If I modyfy a tune that is already in the car, I can Just Write calibration to update the change I just Did
    Instead if writing it completely.

    Do My understanding is correct ?

    Thanks

    Yes.

    Very few things require a write entire. Things like operating system changes or segment swaps require write entire. Everyday normal changes only need a write calibration.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
