A/F Ratio Shut Down Switch
Ref: DT021
DynoTune A/F Nitrous switch with remote mountable staus indicator LED! Fully adjutsable for air/fuel ratio. Works with your OEM o2 sensor or a WideBand controller. Sold as a kit or use with your own wideband controller.
The DynoTune Air/Fuel Lean shut-down switch is the original and only A/F switch available. This tiny stand alone device(you need nothing else to make it work other than your factory o2 sensor or wideband controller) is a Microprocessor controlled Air/Fuel ratio Lean shut-down switch that will shut off the nitrous system if it goes lean during a Nitrous run and best of all, It works with your existing OEM oxygen sensor! (0-1v oxygen sensors)(or 0-5v wideband controllers)
When a Lean condition occurs the Switch will shut down the nitrous system or boost controller and the Optional Red status indicator will illuminate for a short period(20 seconds) to tell the Driver what has happened. The display will flash "LLL" to let the drive know a lean condition has occured. The switch will reset and be ready for another run automatically. The driver can then recall and view the min and max Air/Fuel ratio during the run, right on the display.
A fuel pressure safety switch is nice but it just does not work well enough, a bad fuel solenoid or clogged fuel jet, and its all over.
There are only a few wires to hook up and it's very simple. Typical installation takes less than 30 minutes! The switch is compact and will mount almost anywhere. For the ulitmate in accuracy, get the Innovate wideband controller and use this system to monitor your A/F ratio.
The Unit even has an Air/Fuel ratio Display built in so you can monitor the A/F ratio all the time thus eliminating the need for an additional gauge.
Vehicles with Carburetors, Fuel injection, Blowers, Turbo’s, Nitrous, this switch is a must!
It's the purchasers job to ensure thier factory oxygen sensor is a 0-1V style, standard o2 sensor. This will not work with factory wideband sensors found in some new cars. An addtional 0-1V oxygen sensor can be purchased from dynotune.
