With little hopes to anyone replying after so many years, but let's try:
I'd like to run "mild" water/meth injection, just for safety. I am happy with power output on gasoline, I am not happy with EGT (~ 1000C) and I just want to lower it all together under high boost and high rpm.
My car has wideband and lambda control at WOT. If it detects rich, wouldn't it simply cut down fuel trying to meet target lambda automatically? Why would it be needed to change maps for less fuel to compensate for water/meth?

Beacuse at lambda 0.9 you need 6:1 AFR for methanol
So the ECU will try to reach 0.9 lambda but for that you need twice more injected methanol
Look at table, don't forget ecu measure lambda

If you run pure methanol...
Adding a bit of methanol on top of gas should be a completly different story.

Essentially this is what I am intending, just to keep EGT below or around 900C tops. My EGT gauge is actually a PID controller with a built in relay and I intend to wire the pump for meth to that and only spray as long as I am over 880C for example. By default the meth is boost controlled, which I don't need. I don't think I will make any changes to the fuel maps with the intended setup.
