THUNDERJET™ KIT FOR KEIHIN CV CARBS
The K&N Air / Fuel Monitor is a precision instrument designed to help performance enthusiasts calibrate an optimum air/fuel mixture ratio. This device will work on carbureted, injected, supercharged or turbocharged engines using unleaded gasoline, alcohol, propane or nitrous oxide. It will not work with nitromethane or diesel fuels. Using the instrument to monitor the engine’s air/fuel mixture ratio, a tuner can adjust for power, economy and/or improved drivability. |
To
“read” the air/fuel mixture, the system uses an oxygen sensor to sample the
exhaust gas. The sensor “sniffs” the exhaust and measures the amount of
oxygen present in the spent gases. When used as part of a computer controlled
feed-back system, the oxygen sensor tells the computer (via a small electric
signal) when the air/fuel ratio is rich, lean or just right. The computer reacts
to the signal by re-calibrating the fuel delivery system thousands of times per
second. This feedback control loop, or “closed loop” system maintains a near
perfect air/fuel ratio throughout the entire operating rpm range. Your K&N
Air/Fuel Monitor uses this same electric signal to illuminate a group of 10 LED
lights that correspond with an air/fuel ratio scale. Reading the scale will tell
if your fuel calibration is rich, lean or just right. Using the Monitor as a
tool, a tuner can adjust for peak performance, economy and/or drivability under
any load condition or throttle setting.

The
monitor reads oxygen left in the exhaust regardless of what fuel is used, so the
number of lights and the corresponding scale remains the same. Monitors have
red, yellow and green lights that require 100 millivolts per light for a total
of 1.0 volt.
A K&N Air/Fuel Monitor has many uses. For example, it can be used as a
guideline for preparing a vehicle for emissions testing or as a piece of
dynamometer test equipment. Or calculate the amount of carbon monoxide (CO) and
hydrocarbon (HC) emissions as related to the air/fuel ratio. Leaning the
air/fuel mixture reduces CO and HC emissions. The Air/Fuel Monitor can also be a
helpful tool when setting the idle mixture screws on an engine equipped with a
large camshaft and automatic transmission. Chock the wheels, start the engine
and put the transmission in drive. Adjust the idle mixture screws until the 8th
light on the Monitor glows steady. The engine should then idle in drive without
stalling.
Installing an oxygen sensor in each exhaust pipe is an excellent way to confirm
a fuel distribution problem. If you would like to monitor both banks, install a
second oxygen sensor in the other pipe. Then switch between the sensors with a
switch (purchased locally).
**** NOTICE ****
The
oxygen sensor in your K&N Air/Fuel Monitor assembly is not compatible with
leaded fuels or any fuel additive containing lead. Leaded fuel will contaminate
the oxygen sensor causing it to deliver a false reading. The Monitor can,
however, be used to momentarily test an engine burning leaded fuel. Simply
install the sensor - re-calibrate the fuel delivery system to deliver the
desired air/fuel ratio - then remove the sensor to avoid prolonged exposure.
This short term exposure will extend the useful life of the sensor when testing
an engine burning leaded fuel, but eventually it will become contaminated. Once
contaminated, the sensor must be replaced to restore the accuracy of your
instrument. Additionally, since there is no efficient way to test the sensor,
there is no way to determine the level of contamination. Therefore, we recommend
periodically comparing a used sensor to a new one.
Other products that will contaminate or clog the sensor are:
• Gas/oil mixture • Injector or carburetor cleaners contain lead additives
• Octane boosters containing lead • Other “secret potions”.
