Well, there is a boiler cleaner called Scav-Ox that is 35% hydrazine by volume. Theo-rectally, I can get it from the local C&C chem supply.

dude first off hydrazine will freakin kill you if you even breath it in hehe, its some nasty ----.

and the only thing i will actually ADD to the thread is regarding the a/f ratios. i imagine it will work the same as expelling UNBURNT fuel. im pretty confident you wont be able to burn that water so it in theory shoould actually cause the engine to run leaner. ie displace the oxygen. same with running so rich you actually expell unburnt fuel, it causes a lean indication even though its actually super rich.

The amount of displacement is trivial unless you pass the 50% mark (targeting stoich AFR with 50% water leaves a ~10:1 air-liquid ratio - given densities involved, bullshit difference of airmass or volume).

When you run rich and read lean, it is due to ignition misfires... oxygen is unburnt since that power cycle Abort/Retry/Failed. Wideband picks up the unburnt oxygen. Water can be ingested in HUGE volumes without causing misfires, although in the 150% ratio range need 20-30 degrees more ignition timing to run "normally."

im just tellin ya what i got from innovate... they say unburnt fuel will cause a lean indication even though its the opposite. im just kinda guessing that water would do the same.

Klaus has problems speaking layman.

When he said unburnt fuel, he mean from a total/partial misfire situation, where the overly rich mixture hindered the burn and left unconsumed oxygen.
