ok.. so I too am trying this HOM mode without high octane fuel...
My mods are about the same as Turbojack's with the exception that I have a voltage based MAP clamp.. (tricks the ECU into thinking less boost)
When reading the paper posted on this website, this line caught my attention:
When adding 5%-7% water to fuel without leaning rich fueling levels - a degree or two of advance will produce almost the same power result as without water injection (leaning slightly will increase the power output). This is good for people who have engines tuned for high octane or race fuel but on a daily basis want to use lower octane grades. This is purely an economic use of water injection - power use requires fuel and timing tuning.
So would it be correct to say that running 5-7% would actually be better for our purposes... instead of running 10-15%?
Assuming we got ourselves to a 11-12 AFR... then turned on W/I at 5-7% and not retuning at all?
Thanks for your input.
