@negativevolume, it's G*e-3. I'm using kg-mm-ms-kN units. The HIC graph is adjusted by that factor we have to enter in the ASII window.

@dummy-error if you are going to calculate HIC, you need to make sure head acceleration is in G's. You are seeing huge HIC values because you are calculating HIC from G*e-3. 

Also, since you are dealing with head impacts, generally HIC 15ms is used as an injury criteria, not HIC 36ms. 

Try both of these changes and lets see how it looks.
