Venom's Computerized Nitrous Systems maintain the proper air/fuel ratio at any bottle pressure and will terminate the flow of nitrous to the engine should the air fuel ratio become too lean. Nitrous delivery is available by pushing a button while at wide open throttle. A dash mounted L.E.D. informs the system status and/or displays fault codes. Kits monitor the factory O2 sensor to adjust the mixture of fuel and nitrous. The system controls the factory fuel injectors for fuel enrichment to provide the optimum air/fuel ratio when the nitrous is injected. Designed to be used on multi-port EFI systems with or without a return fuel line. Easy installation with no cutting of stock wiring harness required. Kits include a 10-lb bottle (not filled) and all necessary components to install on a fuel injected vehicle.
