BQ34110EVM-796: How to scale the capacity

Hello,

I am working with a 170 Ahr PbA battery, but the BQ34110 is rated to 32 Ahr. The data sheet says I can scale he capacity, and I believe it mentions two ways to do this: 1) "by scaling the actual sense resistor value compared with the calibrated value stored on the device", and 2) by scaling the calibrated current ("Scaled current measurement is achieved by calibrating the current measurement to a value lower than actual."). The data sheet doesn't go into any more detail.

So, how do you achieve an appropriate capacity scale? 

Thanks.
