OBD2PDA and OBD2LT are the software programs used to collect data in the field using an OBD-II interface with either a PDA or a laptop. With the introduction of PC-Travel Version 2, with support for the new mapping features which greatly simplify the data collection and analysis, these interface options have become much less important since the mapping features are not available for data collected with OBD interfaces. However, if you can’t use GPS receivers for some reason then these are an option.
