Now your BMU is just thinking, you have a new battery.
Only DBCAM or the complete tripple needs to be done.
Make a BMU reset is still something that might cause some risk, but in general it allows the car to restart the SOH tuning process, which by nature/firmware is pessimistic, so by reset and set SOH back to 100%, it will give many weeks/months with enhanced EV range.
The risk is to potentially over discharge the battery, but ... BMU might have a protection over under voltage even when in use (after 2h rest the SOC is recalculated based on voltage, so over discharge protection kick in, if car get some rest before next EV trip)
So .. it will be interesting to see how low the voltage might go, since changing SOH from 26.5Ah to 38Ah .. is might cause fully discharge the battery .. since 70% of 38Ah is more then the previous SOH.
arnyswart can update us how car behave in long EV usage, and clarify if in this case the SOH was low for real battery degradation or wrong BMU firmware
