For inductive ignition systems it is recommended to use 90% maximum
level and 200 RPM progression range. For capacitive system, like
MSD, it is recommended to use 100% maximum level and 1 RPM
progression range.

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.
When experiencing problems with the cut through MSD like no cut
at all or RPM limit always 500 RPM above what was setup, use the
other MSD pin.

compensation. For MSD
and Spark
, use 45us.
PRO
That’s the delay time the ignition module has 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
check with its manufacturer.

setup parameters
Default:
This mode makes available the options that are commonly
used for the majority of engines, with standard injection angles and
configurations.
Custom:
This mode enables all the options related to the fuel control, as
customizable injection angles, etc. When using this mode, fuel injection
configuration can only be done through a PC with FTManager Software.
It is also possible to customize all the fuel tables and RPM positions,
adding RPM, TPS or MAP points according to the engine needs
Fuel Banks:
select primary and secondary (if used) banks control
mode.
Multipoint:
All the injector’s outputs will fire at the same time, as
batch fire.

Semi-sequential:
in this mode, injectors are fired once per engine
revolution, at 0° and 360°, in pairs, according to the twin cylinders.
In a 4 cylinder engine, cylinders 1 and 4 will be fired at the same
time, then cylinders 2 and 3 at the same time.

Sequential:
in this mode, each injector output fires only a single time
per engine cycle (720° on a 4 stroke). This mode is only available
when a cam sync sensor is properly set up.
