Hello

Im new to autocal/flashscan.

Our dealer have read with autocal, a E55 ecu, wich is flash only supported.
He have sent the readout to me, (saved from the scan and tune sw), because it didnt show up in the efilive explorer as a read file.

The filename of the read file was E55.ctz and file size is 933kb.

I have 2 questions.
1. How can i export a file , so i can modify it in any other external editing software, and how do i import the file again before saving it for my customers autocal.
2. When i modify the file in any other software, do i need to do a checksum correction on the file?

Thanks.
