20A 48V controller/battery on a 36V 500W motor?

The brand itself is unknown. Came with a Samebike foldable ebike 36V15Ah. But I changed the original controller for a KT brand. There is no info about the motor other than the Wattage rating and that it has Shimano gear shifter so that's why I mentioned it. I took E-HP simulation as a guideline, thought it probably would be the same.

Thanks anyways. If I need to limit the current in order to get the same power curve for the motor then I need to find another LCD display. Still unsure If i need that, or simply lower the throttle speed to 70% since I'm apparently not reading the simulations right haha.

You don't need to change anything, neither do you need any special switches. Your motor will probably have no problem with that controller. There is a setting in the LCD (C5) to reduce the current if you feel it's necessary. The KT controller uses current control for the pedal assist, Only level 5 gives max current, whatever you set it to.
