Nitrous oxide seems scary to some, but safe operation is assured IF best practices are followed. As the saying goes, "Power is nothing without control" and that's why a sophisticated controller, like the PSN-1 gauge, makes or breaks a system.
The PSN-1 is a high-tech approach to ensuring safety with nitrous oxide. If a lean condition occurs, the nitrous solenoid will be immediately shut! As such, the kit includes a 1500 PSI (103.42 BAR) pressure sensor, LSU 4.9 wideband oxygen O2 sensor, 8 ft sensor cable, relay w/harness, O2 sensor weld-on bung, black/silver bezel, black/white faceplate, serial program cable, & installation manual.

Installation of the PSN-1 is relatively simple. Complete documentation is supplied, and the support pages, application notes and tuner resources can also speed you on your way to effective tuning.
