Under some rare circumstances it is possible that the heater calibration data in the LC-1 can
become partially destroyed. This can manifest in the above-mentioned errors. Follow the steps in
chapter 4 ‘First time use’ to reset the heater calibration data.
7.7 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 LC-1 and operate the sensor in free air. 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.
Sensor timing errors are also common when the sensor overheats. Relocate the sensor further
downstream in the exhaust, install a heat sink or Heat-Sink Bung extender (HBX-1).
Sometimes it’s possible to encounter Error 08 when the exhaust gas suddenly gets too rich.
Normally the LC-1 will display a ‘too rich’ indication if the exhaust gas is too rich. If the mixture
gets rich very suddenly, the LC-1 cannot distinguish between a too rich condition and a sensor
timing error.
7.8 Analog Output tricks/hints
Sometimes there is a ground offset between the device that receives the analog output voltage
and the LC-1. This can be especially true if the System ground is not connected to the same
ground as the measurement device using the analog out. Both devices reference different
grounds and therefore see different voltages. So to compensate for the ground offsets the analog
output voltage points have to be shifted by the ground offsets. To measure what the real ground
offset is, you can program the analog outputs temporarily to output a flat line voltage by entering
the same voltage in both fields for the two analog out programming points. This way the analog
output voltage will be fixed, independent of current AFR and can therefore be measured and
compensated for easily.
To log analog outputs from the LC-1 into an LM-1, simply connect analog output #2 (brown wire)
to an available input on the LMA-2 (RPM converter Aux. In Cable) or LMA-3 (5-sensor “AuxBox”).
Set LogWorks inputs match the LC-1 outputs. As discussed in section 7.6 above, factory settings
for the second output is programmed where 0V=.5λ (AFR of 7.35 for gasoline) and 5.0V=1.523λ
(AFR of 22.39 for gasoline).
Note:
The analog outputs are NOT designed to power other devices or sensors.
So using the flat-line setting at 5V and expecting to power a sensor from it
will not work and can damage the LC-1.
