rather as an aid during tuning. To use a 5 volt sensor, a jumper shunt needs to be installed on
the E6A circuit board. This shunt may be later removed when the UEGO probe is replaced by
the standard 1 Volt sensor once tuning is complete. Please contact your Haltech

representative for details on using this feature. The type of oxygen sensor used is
15.3 Using Different Oxygen Sensors
Almost any oxygen sensor can be used with the E6A. The sensor available from Haltech
TM
is
an NGK heated four wire oxygen sensor. This is the preferred sensor to use due to its
temperature stability and the switch-like characteristic of its transfer function. Other sensors
such as three-wire and single-wire units may also be used, but be wary of slow reaction times
and poor repeatability with cheaper sensors. Wide-band oxygen sensors may also be used, and
can be particularly useful as a tuning tool, both via the engine data page or in datalogging.
[When viewing O2 sensor voltage readings from a datalog, remember to allow for sensor
response time.]
