where:
ParameterAverage
t+5ms
= the parameter average at time “t+5ms”
α = ILAM (for Ip1, %O2,

, AFR, Φ , FAR) or
I2NX (for Ip2, NOx) or
PLAM for pressure.
These user-programmable filters range from 0.001 (heavy averaging) to 1.000
(no averaging).
Parameter
t+5ms
= the parameter value at time “t + 5ms”
ParameterAverage
t
= the parameter average at time “t”
The default averaging filter values are given within square parentheses in Table 1. These
values and the length of the pressure line assembly should not be modified without first
consulting ECM.

SKEW
SKEW allows the parameters NOx, P, AFR,
Φ , FAR,

, and %O
2
each to be modified by a
programmable transform of the form:
ParameterSkewed = M x Par B [Equation 3]
where:
ParameterSkewed = NOx, P, AFR, Φ , FAR,

, or %O
2
value after being skewed.
Parameter = NOx, P, AFR, Φ , FAR,

, or %O
2
measurement before being skewed.
M = Skewing gain. The default values for M are 1.000.
B = Skewing offset. The default values for B are 0.000.
The skewed parameters are displayed and output (i.e. analog outputs, CAN).
CONF (Configure) Setup Option (LEdS, 1V4V, CAN, MOdE, FACT)
CONF setup appears at the end of the setup list for the lower channel. To enter CONF, press
the SYS key until “MOd” appears on the upper display, press the

key until “CONF”
appears on the bottom display, and then press the ENT key. CONF relates to display head
(as opposed to NOx module or sensor setup).
