Hey Bob
hope it goes well for you, so far I haven't needed to change any of the default power curves I have found a good enough range in there to cover most of my cars. I did change one setting to try out the process but rarely use that configuration.
There is a draw back to a wireless controller. I got down a box of bits and pieces looking for something the other night. Having secured the piece I wanted and added it to the car I couldn't find my controller - 5 mins of looking later it dawned on me to check the box - sure enough I had packed it away with the other parts.
