Wakinyantanka,
Currently the range for CF and BA are 511.Most likely due to the 2.5~5V range of the LEM which corresponds to 511 steps of the 10-bit(1024) range of the Atmega A/D. This voltage range shouldn't change with Paul's Melexis part for high amp controller. So 1000A will still be conveyed over the same 511 steps. In my firmware there is a "scaler"parameter associated with motor amps. It was added because my custom Cougar firmware's full throttle range is 600A versus standard 500A, so I needed to scale CF's 511 range to 600. I see no problem with this being able to scale to 1000A.
