“Programmed boost when TPS is over” is the minimum TPS value to
activate the boost solenoid. When the progressive output is selected,
boost output is progressive to boost table, starting at 10% to the
“Programmed boost when TPS is over” value.
•
The recommended frequency for most PWM 3-way valve is 20Hz.
The output signal depends on the solenoid instalation. Check
Chapter 13.8 for further information.
• Select if you want to use the Boost+ button.
The boost duty cycle for 2-step is the boost level when the 2-step is
on, desconsidering any other boost table.

At last, there will be the boost duty cycle table by rpm, speed or time.
The boost by time starts after the 2-step release.
19.12 Boost activated output
This function is used to activate an auxiliary output according to MAP
readings.

There are 3 different activation modes: “always active”, “active only
on 2-step” or “Not active only on 2-step”. This means that even if
the vaccum/boost conditions are met, the activation mode condition
must be respected.
As safety features, minimum TPS and RPM values can be set, so the
output will not activate if one or more conditions are not met.
19.13 Tachometer output
By default, the tach output is configured in the grey #8 wire, but can
be set in the yellow wires also.

If one of this outputs are not available, the blue #1 to #8 and grey #1
