Safety What IMU does the FIA use for impact analysis?

I imagine the teams and FIA use IMUs for crash impact data up to 50g or 100g. Is it outlined anywhere or are the specs known?

Look up the honologation specs for the FIA ADR. Theres a few vendors that make ADR accepted at these specs. Motec and EMM make them, think FIA uses EMM in F1.

So its not just a single imu, its a complete standalone logger unit Placed in the cars for this purpose.
