Alfa 166 2.4 20V '03, Dashboard connects briefly and closes few seconds after

[davidalfa166]

This has been happening since ever, I bought the car circa 2015, I could never properly connect to the dashboard.
Some older versions complained with wrong ISO code, also disconnecting.
Current v4.8 keeps doing the same thing.
I can enter and quickly delete any errors before it closes, so it's not completely broken, however when trying do access other settings the time runs out.

Regards!

I'd start from checking adapter settings?

Why? It connects to everything else just fine: Engine, ABS, Airbag, Xenon... It's only the dashboard. If it was a cable program it wouldn't connect at all?
I'm using the blue KKL cable with the switches. Replaced the internal FTDI controller with a genuine one just in case, didn't make any difference at all, in anything.
Appart of the ISO error warning, it correctly shows the ecu model, serial number, errors... the real issue is it keeps disconnecting after few seconds, so there's no way to do anything.
Seems more likely the alfa 166 doesn't have much interest being a rare model, so the program doesn't support all ecu ISO codes.

maybe KKL cable is to slow for data transfer. try using ELM327 or OBDlink.
as for ISO codes you can always scan it and send report so in the future releases they will be included.
