ive been reading this thread and thought i might shed some light on the subject.I currently have a 2 cell hho generator on my f150 that i have built my self.it has been on my truck for 1 month now and have seen no results i am getting the exact mpg.there are some problems on doing this such as by having a electronic engine your engine will adapt to the extra oxygen in the engine which my thought is the oxygen sensor will detect and richen the fuel mixture.which will cause the engine to burn more gas.now ive done some research on this and you can install a control module to interact the maf sensor i havent tried this yet but i am building it as of now but i will post the results

 

Why break the water into hydrogen and oxygen?
