I guess the obvious question is what models of Bafang motors and what controllers? I installed a Bafang HUB (G311) with a Cycle Analyst Ver 3.1 and it allows you to change the parameters. Go to the GRIN webpage and there is a lot of information there. Videos, documents, and technical information are present. I don't know why you need anyone from AZ or Cal because its all accessible from the internet.
