trying to get my water meth system wired up be for i take it to the tuner. i want it so that when i run out of water meth it goes to a safe setting. does anyone have a clue. is there anyone out there running s300 with water/meth that wants to shed some light.

 

You don't need to do anything. If you hook it up properly to the S300 system, the tuner should be able to use the secondary map in S300 to use the "safe" mode tune you are refering to.

I have the AEM meth kit on my Type R and Jeff Evans was able to tune my car so that anytime a code is thrown on the AEM kit (low fluid, short, etc) it goes into a low boost, safer tune. He didn't have to do any additional wiring or anything.
