To be honest I did some bench testing this morning. Just recieved another new pro8 so that make it that I tried 3 different firmwares on the 3 different Pro8 ecus and am getting file corrupted each time. Plug in the Pro16 and problem sorted. It seems to be an issue with the Pro8 ecu. Tested both pro16 and 2 of the pro8 on the same car, firmware, same usb etc… only variable was the ecu.
I haven’t tried Long Log yet, but it shows more corrupted files.
I’ll see in 1 month, I’m going on a race and I’ll really need it.
There may be a faulty serial …
Firmware update 216.1 is available that solves the problem.
It’s finally working for me 
After all that effort .
