In this case (Yoda model) the ABS print came out good with the standard setup, and the warped bottom does not really matter much.
But often ABS parts look like this (above).
A new z-gap sensor was also installed in a different location, so the temperature changes would not affect the z-gap.
After the print, it is recommended to let the heated printbed and the part cool before removing it, so this takes a little longer than without a heated printbed.
The heated printbed definitely makes the difference for ABS printing.
