To do: What's left to research?

There's still a lot to research inside the dataset, but we've mapped most relevant bytes and understand most of internal logic of the FPA dataset.

What's left to do?

Steeringwheel FPA button

Some sporty models have a specific button on their steering wheel to enable a driving profile. Cars that have these buttons have specific settings in their FPA, namely at these bytes:

• 0x7BE
• 0x7FA
• 0x80D
• 0x817

Unknown group properties

At 0x236, there's a bunch of bytes that change in relation to the amount of configured control groups. Some findings:

• unknown_group_properties[2] is always 40 when groups are used.
• unknown_group_properties[3] is 18 or 1c when there are groups.
• 1c only happens when there are 2 groups
• 18 only happens with 1 and 3 groups, although sample size is a bit small there
• unknown_group_properties[5] and [6] are only used when there are 2 groups
• unknown_group_properties[5] is either 00 or 80
• unknown_group_properties[6] is always 20 when there are 2 groups or more
• unknown_group_properties[7] is either 00 or 01, where 01 only occurs sometimes when there are more than 2 groups.
• unknown_group_properties[11] is only seen in case of 3 groups.
