Lasy, uninformed, people would just put free tap water in .

Thinking I have put tap in my radiator all my life with no problems, not realizing that they have been replacing radiators evry 5-10 years Insted of every 40-60 years. Same thing gos for HHO . You can see this with the DEF people are trying everything they can to bypass the systems. Sighting I allerady have to buy diesel why did they add a gimmick forcing me to buy the blue Juice.
In Las Vegas Nevada my sister is recommended to replace(not flush thats every1-2) the raidator every 5-7 years by many shops, because the tap water is plugging the core with Alkali precipitate. They just call it plugged. .

Also obviously if you tune for water and the system fails or you run out of water it's not good.... But similarly running out of diesel ain't such a good idea either..

Add a floatto the resavor that signals the computer to switch maps and shut down the injection system.

Modern diesel engines are hyper fuel efficient, with astronomical fuel rail pressures, and a multitude of other internal improvements.

Agreeda CR Cummins with a 1-3000lbs weight penalty gets the same MPG as as my aero modded 12V 6BT 5.9-160 mechanical injected Cummins, but there is room for more
Keep up the good work . .
