Multiecuscan

Hi
Is there any functionality to download, backup, and upload the contents of the engine ecu? If not with the current version, could it be added to a wish-list?
Otherwise is there any free to use software that would do this on a Fiat JTD115?
Thanks

No way.
This software doesn't download/upload data to ecu.

You need a specific hardware/software to do that.
Search for chiptuning on internet, is what you need.
