Tuner Studio Setup
Make sure that you have downloaded the latest version of TunerStudio (TS) from here. Although the base version of the software is free, it is strongly recommended to buy a license for the additional features including auto-tuning and the ability to customize the default dashboard.
Begin the setup by plugging the ECU into the laptop and opening TS. Create a new project and click detect under firmware. Select the COM port corresponding to the FOME ECU in the device list. If the COM port cannot be found or the firmware cannot be automatically detected, click Other/Browse and load the .ini file for the ECU which can either be downloaded or found within the ZIP file on the USB device which appears when the ECU is plugged into the computer.
Auxiliary Connector
The middle 17 pin ECU connector, originally for the automatic gearbox on Auto models, or not present on Manual models, has been repurposed for auxiliary/expansion.
Each ECU comes with a connector already populated with leads for a wideband LSU sensor, and the cam sensor, terminals are included for extra sensors or switches you may want to add.
Temperature Sensors
Pins 11 & 12 can be used to add 2 wire temperature sensors, one wire should connect to the required pin, the other to pin 16 (GROUND), there is an internal 2.7K pull-up resistor.
In some builds, it might be beneficial to move the coolant sensor, rather than extending the factory wiring pin 7 can be used for the signal, this in internally connected to the factory coolant pin.
In TunerStudio the input channel will be “Analog Temp X”, where X is the number in the table below. For example, Expansion pin 11 would be “Analog Temp 3”.
Linear 0-5V Sensor (e.g Pressure Sensor)
There are 3 inputs for linear sensors which output a voltage, Pin 8, 9 & 10. Pins 16 & 17 provide a GROUND and protected 5V supply to power the sensor.
In TunerStudio the input channel will be “Analog Volt x”, where X is the number in the table below. For example, Expansion pin 8 would be “Analog Volt 8”.
