DynoTune Nitrous Air/Fuel ratio Nitrous switches Perform!!!
Can You Afford Not To Run One?
The DynoTune Nitrous Air/Fuel ratio switch is the only A/F switch available. This tiny stand alone device(you need nothing else to make it work other than your o2 sensor) is a Microprocessor controlled Air/Fuel ratio switch that will shut off the nitrous system if it goes lean or rich during a Nitrous run and best of all, It works with your existing OEM oxygen sensor!
When a Rich or Lean condition occurs the Switch will shut down the nitrous system and flash the Red status indicator for a short period(20 seconds) to tell the Driver what has happened. The switch will reset and be ready for another run automatically. The LED Status indicator can be mounted virtually anywhere.
A fuel pressure switch is nice but it just does not work well enough, a bad fuel solenoid or clogged fuel jet, and its all over. That pressure switch did nothing to help you.
There are only a few wires to hook up and is very simple. Typical installation takes less than 40 minutes! The switch is compact and will mount almost anywhere. This kit comes with everything you need to install (A/F Microprocessor controlled Switch, Remote LED Indicator, Instructions connectors etc.)
The Switch monitors your engines Air/Fuel ratio (only when nitrous is activated) based on readings from your Oxygen sensor (o2) output in millivolts.
When Nitrous is shut down for a very rich condition it will flash like this.
Note:A/F gauge not included!
When a "LEAN" condition occurs during a Nitrous assisted run it will be on solid Red.
Note:A/F gauge not included
Vehicles with Carburetors, Fuel injection, Blowers, Turbo's, Nitrous, this switch is a must!
The following chart is reference to show when the switch shuts down the Nitrous. You do not even need to use an A/F gauge!
O2 sensor output in mv FULL THROTTLE AIR/FUEL RATIO
.00 17.0:1
.10 17.0:1
.20 16.0:1
.30 15.5:1
.40 15.0:1
.50 14.7.0:1
.60 Dangerously Lean 14.6:1
.70 Nitrous shuts off below .70 14.5:1
.85 Lean Max Power 14.2:1
.87 Max Power normally aspirated 13.5:1
.90 Max Power (Rich) (NOS,blower,Turbo) 13.2:1
.97 Very Rich NOS shuts off over.99 12.5:1
Compare the following features:
Microprocessor contolled
.01 Volt Resolution
Light Weight
12 Volt Operation
Fast response
Super Low Current Draw
Micro Package Mounts Anywhere
The switch comes complete with every thing you need for installation. It also includes the remote status indicator with 5 feet of wire so you can mount it anywhere!
The Air/Fuel switch works with single relay nitrous systems (most systems like NOS and NX, TNT)

I dont really know what the range of measurement is on that.
When I had it on the bike..it was an instantaneous reading (after it heated itself up anyway).
I took it over to kevins shop and compared the sensor in the bike with the sensor in their sniffer....they were identical.
Installing that FJO wideband setup on the bike was one of the best mods ive ever done...I need to get it back and put it back on to figure out whats goin on with the bike now.
The whole setup was about 800 bucks...which is why its owned by a group of people to share..and not just one person ____________
Do not taunt happy fun ball!

I have a MOTEC PLM that I use for on road tuning....works very good for load conditions. My dyno has a sniffer too....oh wait its got a load control brake too
