DynoTune Air/Fuel ratio Lean Shut-Down switches Perform!!!

Can You Afford Not To Run One?

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).

 With its built in Wide Open Electronic TPS Switch it makes installation a snap.

 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 with its built in A/F Display.

Using the units built in Air/Fuel ratio Display will allow real time monitoring so the need for an additional gauge is eliminated.

 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.

Works with Innovate, FJO, PLX, AEM and all other programable widbeand systems.

An addtional 0-1V oxygen sensor can be purchased from dynotune.
