Search for "DashDAQ". It isn't cheap, but it gives realtime readout (and logging if desired) of any of hundreds of parameters including motor RPMs, battery SoC, current in and out of the battery or motors, and other useful things. You have to order the special Volt package, which last I looked wasn't on the website yet.I'd like to get some more information on how the vehicle is performing as I drive. Is there a way I can connect to and download data from a vehicle's CAN or BUS on a leased vehicle?
Thanks in advance!
