I'm having my NOS system installed at this writing, which will be managed by a JWT upgraded ECU with nitrous control module. Do I need an RPM-activated window switch to protect me from missed shifts and bumping up against the rev-limiter under spray, or will my JWT nitrous control module handle that function? Please kindly advise. Thank you.

 

The JWT module will take care of all that for you. Not only does it control when the n2o engages but it disengages the n2o before the rev limiter too.

 

Cool. You're getting the Jim Wolf nitrous set-up. Lucky have you a 95-96 . At a recent dyno meet I attended, a 240 with the Jim Wolf nitrous set-up (65 shot, IIRC), dynoed an extra 50whp when spraying. His dyno curve looked great and his A/F ratio? - smooth as butter. It was a steady 12.5. Looks like their ECU program really works. The Jim Wolf nitrous set-up is also very clean & simple, the main feedline from the bottle goes into a single solenoid under your hood, and from there, another line that goes into your intake. That's it! No dual solenoids, nitrous pressure regulator, fuel pressure tee, and the various vacuum lines and wires that go with it. You'll like it.

 

Thanks. You know, I've seen a few GS 430's around here, too...
