The steps to prepare the log files to submit to GPCCHEM for all the IT based fuel gauges should be the same.

Follow the instruction manual below that applies to your battery pack and collect data per instructions.

The elapsed time column in their ivt log file is not correct. They need to fix the column.

Tommy,

The elapsed time needs to be increasing and also should be separated by 1-4 second intervals.
