Does Dashcommand for iOS use accelerometers for Power measurement?

Thanks!

No, we watch the vehicle speed, and calculate wheel power based on measured acceleration (from vehicle speed) and the vehicle weight entered in the Vehicle Manager.

Whats the sampling frequency when used with an ELM WiFi OBD device? Mine seems to be pretty slow. like 1Hz.

As fast as it can go. This depends on a lot of things, like how fast your vehicle will give out data, how much time the phone takes drawing the dashboards, and how much time the phone takes processing the OBD-II data.

The default Tuxedo skin can be a little bloated, slowing things down a bit, and also the persistent PIDs can hold your data rates down too. If you're having speed troubles, try a different skin set and disable persistent PIDs (both of these can be found in Settings from the Main Menu).

Ah ok. Thanks for the info. I have a iPhone 4s and an iPad 3 so I'm guessing they should be plenty powerful enough. The vehicle I'm using it on is an e39 BMW m5 from 2001. Do you think perhaps the car is the thing being slow here?

I'll try deleting some of the persistent PIDs.
