Pre Turbo Injection - How Much and When to Inject

[rotrex]

At such high water to fuel ratios and a lean mix, the ignition timing numbers look more feasible. I won't use that much mix as otherwise fluid usage on track would become too high. I only run a 1 gallon tank.
Fast Yaris. I liked it.

Are you using a PWM valve to adjust flow over rpm/boost?
I control flow via a aquamist HSV and a separate map in the ECU.
