Tuning from in-dash PC "On-The-Fly"
Basically, you just make a few function calls to a dll (obdiiv7.dll) and all the OBDII data is available to your own application.
EFILive was designed that way exactly for the integration of devices that you are planning.
Alternatively just use the full EFILive Scan Tool. EFILive has a very customizable built in dashboard that (in the next release) can be almost maximised to the full PC screen.
