Aquamist HFS-3 on Toyota Hilux 2.5L D4D truck (2KD-FTV)

[Richard L]

This may be a bit difficult task for the HFS3 if the engine has electronic diesel injectors.
However, it is possible to run the system with the boost. Th ehFS4 is a better choice to handle direct injector signals. Is this approach acceptable for you?

We don't have a wiring diagram for your car. What is the serial number of the controller? The later version of the HFS3 may work with the iDC signals.
