2nd MAP Sensor

This field is only accessible when the Exhaust MAP Sensor is selected on the Spare
Input Function. It tells the software what sensor is being used (either 1 Bar, 2 Bar, or 3
Bar sensor) and how to calibrate the reading.


Aux. In Function

The Auxiliary Input on the E6K can be configured for one of several functions. Most
of these functions relate to the configuration of the system. The available functions
are:

Disabled

No effect on ECU operation.

NOS Input

This input is used in conjunction with 16.14 NOS Switch

TCC Input

This input is used in conjunction with 16.5 Torque
Converter Clutch Lockup (TCC)

Turbo Timer

This input is used in conjunction with 16.13 Turbo Timer
(TT).

Anti-Lag Switch

This input is used in conjunction with 16.15 Anti-Lag
Switch

Flat Shift Switch

This input does not operate in conjunction with any output.
It is used by the ECU to retard ignition timing to 15

°

ATDC, allowing the throttle to be held wide open whilst
changing gears. This reduces engine deceleration so gear
changes will be quicker, but it also prevents the engine
from over-revving when the clutch is disengaged. The
driver normally depresses the switch just as they are going
to disengage the clutch and then releases the switch just
after the clutch is re-engaged. The driver can therefore
keep the throttle wide open throughout the gear change.

Air Conditioning Request This allows the ECU to intercept the vehicle’s Air

conditioning request signal and grant or refuse the request
based on the current engine operating conditions. See
section 16.16 Air Conditioning


Aux. Out Function

The Auxiliary Output on the E6K can be configured for one of several functions. They
are all output to the Aux Out pin (pin A) on plug J7 in the wiring loom. The available
functions are:

Disabled

No effect on ECU operation.

Ignition Bypass

Bypass signal compatible with some General Motors
ignition systems. This function allows the ignition system
to provide the spark at 10° BTDC at cranking speeds
(below 500rpm). This aids starting.

Staging Signal

Logic output that indicates Staging conditions. If Staging is
selected, and the Staged injector are firing, this signal will
be high (5 volts), otherwise it will be low (~ 0 volts).

Tacho Output

Used for driving tachometers when running a multicoil
ignition set-up. This output combines all of the multicoil
signals into one output and this is used to provide an RPM
measurement.

Ignition Toggle

This output is used for rotary set-ups where both the
primary and secondary trailing ignition signals are
