3. Purpose

The STAG-AFR controller for wideband oxygen sensors has been designed to determine the air-to-fuel
ratio (AFR) for an internal combustion engine based on the measurement of oxygen in the exhaust gas.
Measurements are made with a wideband oxygen sensor that may be used in engines fed with a wide
range of fuels such as unleaded gasoline, diesel, LPG, natural gas, methanol and ethanol.
The wideband oxygen sensor provided in the kit
and two-stroke engines.
In both cases, the probe lifetime is dramatically reduced.
ATTENTION!
STAG AFR is an alternative to expensive exhaust gas analyzers. Due to high-speed measurements of
lambda parameter (AFR - air-fuel ratio), it is possible to control air-fuel mixture not only in steady but also
in transient engine operating states
The kit can be used, for example, for adjusting both carburettor and fuel injection systems, calibrating
LPG/autogas systems of any fuel system diagnostic generation available on the market, diagnostics of fuel
systems, diagnostics of factory installed oxygen sensors and control of air-fuel mixture during chip-tuning
system calibration. Knowing a current air-fuel ratio for the mixture supplied to the engine, the user is able
