AFM-1 precision wideband air
/ fuel meter and data-logger for air
/ fuel measurement and air / fuel
ratio analysis and diagnostics.
Here you will find well engineered and
manufactured electronic measurement and
control products for internal combustion
engines. Our products are best suited, but
not limited, to automotive and motorcycle
performance sport applications. Because of
it's general design and interface, most can
be used on any car or motorcycle engine.
We also publish on our web pages every detail
about our products, it's design, particular
technology and possible application.
A DIY air fuel or lambda meter kit
is also available for the Do It
Yourself individualist.
Detailed pricing information can be
found by visiting the secure
Micro-Craft eStore.

AFM-1 Wide-Band Air Fuel Meter with
real-time data logger :
| |

This hand held instrument uses a
Wide-Band O2 sensor (Bosch LSU-4),
which allows the user to take
precision Air-Fuel-Mixture
measurements through oxygen
concentration analysis in the
exhaust gas.
Additional connectivity is provided
for various inputs, like RPM, Throttle-Position-Sensor,
Manifold-Absolute-Pressure,
Mass-Air-Flow, and up to eight
K-Thermocouple temperature inputs.
Programmable O2 Sensor simulation
outputs allow you to control a stock
fuel injection, an external gauge or
indicator of your choice.
The instrument can be connected to a
MS-Windows computer to facilitate a variety
of functions like real-time data-graph and
data-logging. |
Graphical control software :
|
|
The
MS-Windows based graphical
application control software allows
for complete control of the
instrument, it's configuration,
multiple real-time graphs, the data
logging process and advanced
diagnostic.
All input values are displayed in
numerical form and as a dynamic
bar-graph.
Up to five real-time graphs can be
used for a dynamic analysis of your
engine condition.
Several configuration dialogs
provide a very comprehensive setup. |
Wide Band oxygen sensor :
| |
The Bosch LSU-4 Wide Band exhaust gas oxygen sensor
is used in several European cars,
specifically in some new Volkswagen models and provides
therefore a very affordable solution for precision
Wide Band Air Fuel analysis. |
