RPM
Maximum engine speed:
setup the engine maximum RPM. All fuel
and timing maps will be created with its last point on this RPM. This
parameter is also used to calculate fuel injector’s percentage of use.
Maximum boost:
maximum boost for fuel and ignition maps. For
naturally aspirated engines, set this option as 0.0 psi. For turbocharged
engines, use 10psi above the maximum boost the engine will effectively
be using. In case of an overboost, the ECU will apply the last injection
timing set on the map. This option doens’t control boost pressure, is
just a limit for fuel and ignition maps.

MAP
MAP:
this mode is indicated for turbo or naturally aspirated engines.
That’s the mode that better represents engine load, because engine
vacuum varies under different loads, even with the trottle on the same
position.
TPS:
this option is mostly used on naturally aspirated engines with
aggressive camshafts, when this causes the vacuum on idle and under
low load conditions to be unstable. When this option is selected, MAP
compensation is available for fuel and timing maps.
TPS idle fuel injection table:
This is the mode the fuel injection
on idle speed will be controlled. When enabled, a table that relates
injection time versus engine RPM is activated whenever TPS is equal
to 0%. Enable this feature an engines with high profile camshafts and
unstable vacuum on idle.
For street cars with stable vacuum on idle, it is recommended to keep
this feature disabled. In this case, injection time for idle will be set up
directly on the vacuum ranges on the main fuel MAP.
