This unit interrupts the nitrous oxide system at the same time the Pingel Electronic Engine Kill Module interrupts the ignition, this allows clutchless, full throttle shifts while spraying nitrous at the touch of a button. The kill time is adjustable between 40 and 110 milliseconds so the setting on the Pingel Electronic Engine Kill Module can be matched. Ideal for use with automated shifting systems. The module is very small measuring just 2.375' tall x 1.625" thick.
