Autotuner only does checksum via obd2, does not do checksum for bench flashing backup...

Ohhh yes.. Autotuner politics/ideas are nonsense... I don't know why they limit the possibilities of a good device.. If they didn't do that, I would have used it a long time ago, and instead I decided to not buy it a long time ago

Autotuner is tool for fast read/write calibration data for tuning and to clone ECUs with backup files. If You want to do advanced mods outside calibration it's necessary to buy other tools, like PCMFlash+Scanmatik for MD1/MG1 or WїиоL5 plugin to correct checksum manually.
