Prior Release Notes

CarChip Software version 2.2 includes the following changes:

The Tools Menu has been added to the menu options on the tool bar. The Tools Menu contains three new options for organizing trip data and keeping track of readiness code information. These options are.

Fuel Entry - Lets you enter information about fuel usage and costs for every vehicle you have added to the CarChip software. Fuel entry information is used to calculate the price you pay per mile for fuel and is displayed in the CarChip Home Page and Vehicle Summary View.

Emissions Readiness - Displays the last recorded status of the emissions readiness codes for every vehicle in the CarChip Database. Use this dialog box to view whether or not a particular readiness code is supported for the vehicle and whether or not the monitor completed its test for each of the available readiness codes.

Trip Type Entry - Lets you categorize the all the recorded trips by trip type and provides a mileage analysis of the types of trips taken.
