I/P Switches
The I/P Switch menu is used to enable and configure auxiliary input functions. Inj 6,7 & 8
can be used as switched inputs if not used for fuel. Also HIS 1, 2 & 3 can be used. The
analog inputs but can be used as input switches if a pull-up resistor is used, see wiring at
the end of this manual. Two different I/P channels can use same analog input pin, some
I/P channels can have different thresholds for turning on/off functions at a specific
voltage.
When selecting an input channel some functions will be available through other menus
like I/P Traction control, launch control, WOT and more. Some auxiliary functions may
also need to be configured under O/P Setup to be available like Anti-Lag and others
before the menu will be available.
Chose a function and press “Enter” and you will be directed to a list of selectable inputs,
variables or just enabling a function without any input pin (Continuous) .
Example below:-
Select I/P Launch press “Enter” then select continuous press “Enter”, the function
will now always be on. If using a speed sensor and configure Launch under menu
M5 Launch Control you will have a fully automated Launch control. Anti-lag select
channel 3, Boost SW1 select channel 7 Inverted (press key “i” before enter).
