I've been messing with a DPC18 on a Frey HT1000 with and ultra motor, this has torque settings and I've figured out that the DPC18 that's locked to 5 levels also uses the eco/sport to actually overirde some of the torque controller settings, which is why BBSxx people don't notice any changes, just pulls levels 1,3,5,7,9 from the controller and the eco/sport has no effect. I changed to a 500C display with 9 levels and everything was how I programmed it. The DPC18 I have is version 3.0, I'm fairly sure the previous versions are OK (no eco/sport and you can set 9 levels). For someone who uses the config app and sets up their motor exactly how we want, the DPC18 V3 is an abomination and waste of time.
