telling which one is the correct option (without an oscilloscope), select the option Falling Edge. If the engine starts with
misfires, change this parameter to Rising Edge.

maps are unavailable and only the fuel control is enabled. Gray outputs are free to
be set up as injectors or auxiliary outputs.
Default: this mode makes available the options that are commonly used for the majority of engines, with standard firing
order tables and configurations.
Custom: this mode enables all the options related to the ignition control, as
customizable firing orders and angles, etc. When using this mode, ignition
configuration can only be done through a PC with FT Manager Software.
Ignition mode: select if the ignition will be controlled in sequential (cam
sync sensor needed) or wasted spark modes or if a distributor will be used for that
control.

Rising edge (MSD duty 50%): select this option when using
MSD, Crane, Mallory or other capacitive discharge ignitions (CDI).
This mode has a fixed 20% duty cycle signal.

IMPORTANT: some ignition modules (like M&W ignition) have configurable trigger edges. Be sure to check this on the

External cut: this mode is only available when using a distributor and a
MSD ignition module. Enabling this option means the ignition cuts will be
performed by the MSD using the Legacy input they have.
To use MSD Legacy cut a FT500 white wire has to be connected to the
MSD Legacy right pin. By standard, White#10 is setup as ignition cut.
Ignition delay time:

between receiving a signal to spark and effectively spark at the plugs.
Time is given in microseconds (uS).
For MSD and SparkPRO, ignition delay time is 45uS. For other modules,
