Adding to an existing I/O on/off requirements?

[forcefed86]

Currently have the nitrous input and outputs setup and running a single N20 dry shot. (50 shot). I’m using this strictly to spool a turbo off the line. Aside from wiring in a pressure switch, is there any way to have the MS3x shut the nitrous off at a set boost level? I’d like to set the nitrous up to shut itself off once I build 15lbs of boost, and retain the tps/rpm and basic N20 controls.

I’m using an external MAP sensor and still have the internal map sensor onboard that’s doing nothing at this point. Can I set that up to turn off an N20 output at a set boost level?
