Thanks for the article rotrex I will try to read it.

I agree with the theory of water injection acting similarly as ignition retard. The same theory applies when you over inject fuel or when weak/cold spark is used.

I would love to make a chart one day with different water or W/M mixtures at various flowrates including basefuel ,ignition timing and egts with pictures of the spark plug burn to understand better the theory.
