HVKit tuned

Hi to All,

we are using the ti HV-Kit. For some Tests we would like to have 20% more current - since the IGBT-Module can go up to 40A we decided to "tune" the Kit a little bit.
To enlarge it's current capability we changed the resistor dividers between the op-amps and the ad-inputs of the CPU.
R47, 48, 49, 50 = 1K, R25,26,27,28 = 4K7    => this results in a divider of 0.825
As result we extend the measurement range of the current values.
In fact they are 121% comparred to the original placement (R47..50 = 0R, R25..28 = not populated).
To ensure that the Algorithm is calculating with the correct current values we also changed:

Original Values:
#define USER_IQ_FULL_SCALE_CURRENT_A  (10.0)
#define USER_ADC_FULL_SCALE_CURRENT_A  (19.89)

To our new Values:
#define USER_IQ_FULL_SCALE_CURRENT_A  (12.0)
#define USER_ADC_FULL_SCALE_CURRENT_A  (24.27)

We assumed to get the same Motor ID, but the Motor IDs are different.
The Rs is about 1 Ohm greater on the HVKit tuned.
Is there another scale factor that i must correct it?
To get the Parameter i have done the Labs
Lab2a -> Motor ID
Lab3a -> ADC Offsets
Lab5c -> Inertia, Friction
Lab5e -> Bandwidth
