S300 calibration file size

[Brenden]

Hi
I have a question about the calibration file size.
When I create a brand new calibration and save the skl file the size is around 48,555 bytes.
The file uploads to the S300 v3 fine but if I then download that same calibration from the ECU to the laptop and save that file the skl file is around 11,209 bytes.
Is this normal?
I would figure the file sizes would be the same.

Has anyone seen this before? Is it normal that when downloading the skl file from the ECU and saving the file again, that the file is smaller?
Just trying to gauge if this is a problem

Post each calibration here.

Please see attached
The 47KB file was uploaded the other day
The downloaded file I just pulled from the ECU now.
The downloaded from ECU file will have modifications to it for idle and idle fuel adjustments.

One calibration is compressed; the other is not. You can do a 'compare' and see they are largely the same.

Is it normal?
I know that when a file has been downloaded from the ECU and is smaller if I try to Use the import from calibration feature I get an error Could not find table in calibration. But a file that is 47kb this feature works.
