Nitrous Oxide Systems is announcing the availability of their patented Drive-by-Wire Wide Open Throttle Switch, P/N 15972NOS. The patented NOS throttle switch simplifies nitrous installation on any drive by wire application by eliminating the need for a throttle activated micro switch. A simple dial adjustment on the NOS wide open throttle switch changes the input making it compatible with most drive by wire applications. Two more adjustable dials will allow the RPM’s to be set to activate and deactivate the nitrous system eliminating the need for a separate RPM window switch. The NOS drive by wire wide open throttle switch is compatible with all ignition systems including DIS. The compact design of the wide open throttle switch takes up little space for a easy install. A step by step installation and adjustment manual is included. For more information contact Nitrous Oxide Systems, 1801 Russellville Rd. Bowling Green, KY 42101, Telephone 270-781-9741.
