Changing from default chemistry in BQ3055

I'm using the BQ3055 in a 3000mAHr 4S LiFePO4 pack. As far as I can tell the only impact of using the default chem ID of 0x0100 is that the SOC at reset is not accurate, is this the case?

I would still like to remedy this, how can I update the chem ID to something more suitable? (providing I know what ID to use, 404 for example).

Thanks
