Default Re: Tuning for water injection: fuel, ignition, and EGT

couple of thoughts here :smile:

It's an important tool when you're tuning on the edge - but I wouldn't go as far as stating 'the best method'

2) WI turns on at 3-5 psi boost.
Where did this come from? :shock:
That would only be true for non-intercooled engines mate, or else it's FAR too low

3) Add water injection in the 10-25% range (ramping with boost is good).
on well intercooled engines, over 10% could bog it down. Where did the 25% come from?
Quote:
8) Advance ignition or add more fuel to reach optimal power even at sub 12.5 AFR
I've seen max power at around 14:1 with W.I., so we'd need to verify with others that the 12.5 figure stands in this case
