Please note the options; the M182 option has all factory functions working and some I/O to spare. The M142 version has no spare I/O and does not have: Skip Shift, Eco Mode, EVAP, Fuel Tank Pressure, Cylinder Shut Off.

Also take note of the logging options; level 2 is basically a requirement for any real diagnostic, level 3 adds virtually unlimited channels (2000), up to 1000hz sample rates, and multiple log sets.
