my car is tuned on 27psi, 94 octane with 1100cc water/meth stock ecu. i did not tune the car but to my understanding the ecu is set to lean out when water/meth kicks in.
as in 4psi is when my water/meth module starts injecting slowly(350cc if i recall correctly) , injecting more till 10 psi where injection is 100% at (1100cc), and the map is set up so at 4psi it will lean out the pump gas in correlation with water/meth to create a steady air/fuel mixture.

You can easily tune your car on meth with a stock ECU. However, this is also with the caveat that you know what you're doing (not trying to be an ***). There is a lot to read up on, so I won't get into ensuring proper atomization via nozzle placement or running a direct port set up as an alternative.
The whole premise behind it is that you're able to run more timing and more boost as the Methanol will cool the intake charge (when injected into the intake) as well as add octane. Since methanol is a fuel, when you first install your system and take it for a spin, your car will be running rich. So in turn, you would then pull fuel out of your fuel map in the load cells you're targeting while injecting meth. Once that's done and your AFR's are on point, you'll be able to add timing and gain some HP. This is an over simplification, however thats essentially what would go down.
There are safety features that you can install that will monitor flow. Even warning systems that will sound an alarm and send an output to the ECU in case the flow is too low, or your tank is low. I mean you can basically add whatever you want. I ran a meth set up on a stock ECU for years, when that's what I had. Worked well. I had a trigger box (ZAVT-1) from zeitronix that would sound an alarm and cut fuel if there was an issue. There are lots of ways to go about it.

No, its useful whenever you want to add more timing to whatever desired PSI of boost you're running. You are essentially increasing the octane of your fuel by injecting methanol upstream of the throttle body or via direct port (depending on your mixture of choice) as well as cooling the intake charge in the case of an upstream placement.

Personally, I dont run meth till 30 Psi. Its enough boost for a daily driver. I run meth only 30 Psi + boost and add 2 degrees on top of my current tune to be in safe limits.
Even if the fail safe didnt work, my engine would be safe. I have had good results with it and no reliability issues. All that on stock block.
