Other functions
MAP output analog signal
white 5: Engine temperature
White 7: Air temperature
White 10: TPS
White 11: MAP signal
Input selection
This feature uses an input as analog output
The MAP signal can be read in an external datalogger.
In the FTManager, this setup is at “Sensors and calibration” - “Inputs”
19.15 BoostController
The active control function of the wastegate valve pressure is used
for a more precise control of turbo pressure in street, circuit and,
mostly, drag race cars. The control can be performed by time after
2-step, by gear and engine RPM, by gear elapsed time, by a single
target or by engine RPM, besides specific targets for 2-step, 3-step
and burnout mode.
IMPORTANT:
-
The pressure controlled by BoostController is
the pressure at the top of the wastegate valve.
-
You can set the maximum MAP pressure and
maximum MAP pressure on 2-step.
-
When the BoostController is off the target is
zero, and each time the read pressure, for any reason,
exceeds 1.1psi the decrease solenoid is activated.

19.14 MAP signal output
By default, this function is set in the white wire #10. Due to hardware
design, the MAP signal output is used in of the inputs (white #5, #7,
#10 or #11 only).
