# Decoding BMW laptimer application mpower files
I came accross the BMW laptimer software which can export it's data, but I found no quick way to decode them.
Information I gathered so far:
- mpower files are in fact zip archives. Rename them to .zip and you can open the archive.
- the archive itself consists of many .far files
Far files are binary encoded in the following form:
acceleration.far: 8bytes version hex
entries:
8bytes float time
8bytes float acceleration ?
8bytes float acceleration left-right ?
8bytes float acceleration up-down ?
acceleratorPedal.far: 8bytes version hex
entries:
8bytes float time
8bytes float (0-100)? pedal state
brakeContact.far: 8bytes version hex
entries:
8bytes float time
8bytes (hex?) brakestate
speed.far: 8bytes version hex
entries:
8bytes float time
8bytes float speed
consumption.far: 8bytes version hex
entries:
8bytes float time
8bytes float consumption
This file seems to be empty for my car (i3-BEV)
currentConsumption.far: 8bytes version hex
entries:
This file is empty except for the version for my car (i3-BEV)
distance.far: 8bytes version hex
entries:
8bytes float time
8bytes float distance in meters
filteredAcceleration.far: 8bytes version hex
entries:
