I am looking for a good way to setup a failsafe on my AEM Infinity for my S2000 with SOS kit with a 1200 Novi on +- 14 psi on a F20C, running a Snow Performance 2E Max kit.
First time using a water/meth kit and I am impressed with the cooling properties.

Have seen the flow sensor, however I am first trying without this sensor.
For now I am using the ModeSwitch to switch ignition map when the WMI tank is empty.

But I cannot figure out how to setup a different fuel map. With modeswitch you can only switch Lambdatarget map?
Is there a fueltrim I can use when triggering an analog input or how do you guys run this? I have seen the Nitrous control, but also works with a different lambdatarget instead of different VEtables.
Or is it intentional so that you always run closed loop lambda while spraying water/meth?

Or for example a rev limiter when an analog input is triggered?

Would like some advice,
