Aux. In/Out Function: The Auxiliary Input/Output on the E6A 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.
Ignition Bypass Output - 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 Output - 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).
Nos Input Input - This input is used in conjunction with the
Nos Optional Output. [16.13]
TCC Input Input - This input is used in conjunction with the
TCC Optional Output. [16.4]
Turbo Timer Input - This input is used in conjunction with the
Turbo Timer Optional Output. [16.12]
Anti-Lag Switch Input - This input is used in conjunction with the
Anti-Lag Optional Output. [16.14]
Since the Auxiliary Input/Output line can only perform one duty, all of the above
functions are mutually exclusive. i.e. although two programmable outputs exist on the
E6A, only one of the Nos, TCC and Turbo Timer may be chosen. None may be used if
the line is needed for Ignition Bypass. Keep this function in mind when deciding on the
E6A configuration you wish to run.
System Mode: This field sets the operating mode for the software. The software can be used
in either Basic or Advanced Mode. Most installations will only require the Basic Mode.
To determine if you need to use the Advance Mode, see the Introduction.
