Trying to decide between the elmscan usb with pcmscan software / odb allinone or the Mongoose cable with the same software. Done searches and read about the differences but just double checking before I place and order. Most likely with this gm I will not be trying to flash or change the computer, just want to analyze more functions datalog and run some gauge screens. The escalade are drive by wire so I did not know if this presented any problems.

If I get a Buick Grand National I might want to do more with that car.

Thanks for any help
