13 Sensors and actuators
FT500 has some pre-defined sensors s possible to setup any kind of analog sensor
on its inputs or even to connect it and read a sensor in parallel with the OEM ECU. This configuration is done on the
custom mode through software FT Manager and USB cable on a PC.
13.1 Intake air temperature sensor
With this sensor, the ECU can monitor the intake air temperature and
perform real time compensations.
Models:
Fiat: Delphi / NTK (3,3k
GM (American): ACDelco: 213-190 / GM n°25036751
One of its pins is connected to the battery negative. The other to the
white #7 wire (standard can be changed).
13.2 Engine temperature sensor
This sensor is very important for a good running engine, as varying engine temperatures dramatically affect an
On water cooled engines, place this sensor near the engine head, reading
the water temperature. On air cooled engines, install this sensor reading the
engine oil temperature.
Models:
Fiat: Delphi / NTK (3,3k
GM (American): ACDelco: 213-928 / GM: 12146312 (or 15326386)
One of its pins is connected to the battery negative. The other to the white
#5 wire (standard can be changed).
13.3 Fuel and oil pressure sensor PS-10B
This sensor allows monitoring of fuel or oil pressure in real-time through the dashboard screen and internal
datalogger. With the Check Control function, it is possible to program pressure warnings. When installing this sensor, the
PS-10B characteristics:
Output signal: 1 to 5V
Electrical connections: Pin 1:
Pin 2: signal output
Pin 3: switched 12V
Connection
Pressure range: 0 a 145psi
Input voltage: 12V
Stainless steel body and IP67
Accuracy (including nonlinearity, hysteresis, and repeatability): +/- 0.5% at maximum readings range.
Electric Connector: 3-way AMP Superseal (FuelTech Code 1014)
As FT500 is fully configurable, practically any automotive pressure sensor can be used if the voltage x pressure
table is known, you can setup through FTManager software.
13.4 Throttle position sensor (TPS)
This sensor is a potentiometer installed on the throttle to inform the ECU about its position. If needed, it is
possible to run the engine without this sensor, but, it is very important for a fine tuning. When possible, use the OEM TPS.
This ECU is calibrable to any kind 0-5V TPS sensor.
