Dry nitrous oxide systems provide fuel enrichment by increasing the fuel pressure to the fuel injectors as the nitrous system activates.

ZEX™ has designed the ultimate Smart Nitrous Oxide System. The ZEX™ Dry Nitrous System, using ZEX™'s patented fuel control technology, reads the nitrous bottle pressure and adjusts the fuel enrichment accordingly. If it is a cool day out and the nitrous bottle pressure is around 700 psi range, the nitrous system will add less enrichment than if it is a warm day and the nitrous bottle is at 950 psi. This unique feature ensures that you always have the optimum ratio of nitrous oxide and fuel, never too rich, never too lean. This ensures maximum power and safety at all bottle pressures. Once armed, the kit is activated at wide-open throttle by a programmable electronic sensor that learns the voltage curve of your TPS sensor. This design ensures your nitrous oxide is engaged at the perfect throttle point every time. The design of ZEX™ Dry Nitrous System makes it the simplest, safest, and easiest to install nitrous oxide kit on the market.
