Its not required to remap the ecu when water injection is installed, but a remap will improve HP and fuel economy because the afr can be put right on top of the max power afr (vs running a bit on the rich side), and the timing can be advanced a bit. This is all relative to a boosted motor that's been highly tuned without water injection.
