safety installation on water/methanol injection

[quattro-nick]

so i building a water/methanol injection from AEM in my car and i want to make a boost protection when the w/m system fails
the little w/m ecu has a wire that becomes a ground when the reservoir is empty or if there is an error
How do I obtain a low boost pressure
maybe if I interrupt the wire from n75 valve? (with a relay)
i have a tial waste gate (44mm) and dont know how many boost the waste gate spring will give
i use vems but have all the external terminals already in use

thanks in advance!

okay,i've read that when the n75 valve is disconnected you only have waste gate spring boost pressure

[Error404]

MFTS will cut boost on an over temp signal (pulls to earth)

That is on motronic though, this chap is running vems. Cutting n75 with relay would work as well. What have you got on the other inputs?

launch control and 2 outputs for clutch and bypass valve for my new twincharged project
