Im looking for a pressure switch to turn off my nitrous when boost comes on, but I dont know which to get. 1-4psi or 4-16psi?

By the time the turbo is producing boost, is it already out of its "lag stage"?

 

I don't know which switch you should use, but if you're running Uberdata, there's a nitrous script that should work for what you want to do.

 

Im running Hondata.

 

Doesn't it already have that functionality built-in then?

 

It has timing and fuel control, but I dont think it has activation and deactivation points.

 

Hobbs switch

I don't think you're right... this pic is off Hondata's website. If it did timing and fuel, it would have to know when nitrous is enabled, which means it must have activation/deactivation points unless it accepts an input. Might be worth looking into it a little more

 

It does know input though, you wire it into the ECU somehow.

 

No, you wire OUTPUT. The switch going into the ECU in the diagram is the arming switch.
