6.6 Sensor Timing Errors
These errors are typically encountered when the sensor does not have outside air
available as reference gas. If you encounter this error, restart the LM-2 and operate the
sensor in free air (remove from exhaust.) If you still encounter this error, the sensor may
be bad and needs to be replaced.
Replacement sensors are available from your nearest VW dealer under the VW part-
number 021-906-262-B or direct from Innovate Motorsports (part number 3737.)
Sensor timing errors are also common when the sensor overheats. Relocate the sensor
further downstream in the exhaust and/or install a Heat-Sink Bung extender (HBX-1).
This problem is easier to diagnose as you will only see the error code come up at wide
open throttle.
Sometimes it’s possible to encounter Error 08 when the exhaust gas suddenly gets too
rich.
6.7 Connecting the LM-2 to simulate a narrow band oxygen sensor
It is possible to install the wide-band sensor in place of the OEM oxygen sensor. In this
case the meter's analog output signal will replace the OEM oxygen sensor's signal to
the fuel injection computer. Note: Please review your analog output settings, the
configuration for a narrowband is 1.1 V for an AFR of 14 and .1 V for an AFR of 15.
EFI equipped cars typically incorporate a narrow band oxygen sensor. These sensors
are typically 1, 2, 3 or 4 wire sensors. Some vehicles are equipped with oxygen sensors
that do not produce an output voltage but change their resistance depending on exhaust
gas content. These sensors cannot be simulated. They are used in less than 1% of all
vehicles. Refer to your vehicles specifications if you think that your vehicle may be in
this category. The same is true for vehicles already factory equipped with a wide-band
oxygen sensor. These cannot be simulated either.
Some EFI-computers will create a fault when the heater power wires of the oxygen
sensor are disconnected. In this case mount the old oxygen sensor in a safe place (but
not necessarily in the exhaust) and connect the heater wires to it to keep the EFI-
computer happy.
Be careful where you mount the stock sensor, as heated sensors will get hot.
