Yes, this is totally fine with me. Since posting I have hit the "too many failures" case with my diff now, right after tuning, so this helps my device a lot, but isn't perfect. It recovered after this, and there have been many other times when it has made 1 or 2 retries.

I have no hardware bus analyser, but maybe I can find a Windows machine with a software analyser to see if ThermoHID / UTAC do something different.
