FuelTech FT500 To FT550 Adapter Harness
This quick guide covers the basics about going from an FT500 install to the
FT550 using this adapter. Read this guide carefully to make the most out of
your new FT550.
Converting Maps
The map files from the FT500 are fully compatible with the FT550, so just open the map file on you computer or read it from the FT500, and write it over to one of the available memory slots on the FT550.
First start with your FT550:
When starting the engine for the first time it’s important to check some
basics:
- TPS: go to TPS calibration screen under “sensors and calibration” and make sure the TPS is calibrated and working perfectly.
- Fuel Pump: Check if the fuel pump comes on when the ignition is ON or when the engine cranks.
- Signal RPM: when cranking the engine, check if the ECU receives RPM signal.
- Sensors: check if temperature and pressure sensors show correct values (engine temperature, oil and fuel pressure and so on).
Ignition: After the engine starts and runs, use a timing light to check the ignition calibration, refer to the FT550 manual for instructions on that.
Stepper Motor
In some cases, where the engine uses a stepper motor and after using the adapter it doesn’t open or closes, a pair of yellow wires must be switched on the adapter, Yellow 1(pin 22) switched with Yellow 2(pin 23) And Yellow 3(pin 24) switched with Yellow 4(pin 25).
- Push the lock (9) inside the connector(10)
- Pull the wires out of the connector
- Switch the position of the wires by inserting Yellow number 1 where Yellow number 2 was and vice-versa
- Push the lock(9) on the other side of the connector to lock the terminals in the correct position
Extra features
Shift lever strain gauge connector
A separate connector is provided to be connected directly to a shift lever
strain gauge, so as to use the internal power shift feature without the use of
an external controller.
The pinout in this connector is as follows:
- White 13 – Pin 18 – Connector B
- White 14 – Pin 19 – Connector B
- Green/Black – Pin 26 – Connector B
CAN B connector
This connector allows other equipment such as a RacePak dash to be connected
to the CAN network.
The pinout in this connector is as follows:
- Yellow/Blue CAN LOW – Pin 3 – Connector B
- Red/White CAN HI – Pin 4 – Connector B
Pinout for vacant wires on the adapter
The following table shows the vacant, extra wires that are not used on the adapter but are available on the FT550 connector.
