The TFZJ100X, also called FZJ100Link, is Link's G4X plug-in ECU for the 100 Series Land Cruiser with the 1FZ-FE inline six. It replaces the factory ECU in its original location on the original loom and takes over fuel, ignition, idle and auxiliary control, so the truck keeps a clean, factory-style install.
Fits
- Toyota Land Cruiser FZJ100 with the 1FZ-FE inline six, manual transmission
Before you order
- Manual transmission only. Link states automatic models will not work with this plug-in.
- Link lists only the FZJ100 with the 1FZ-FE. V8 (UZJ100) Land Cruisers are not covered.
- It works with both factory ECU types, 3-plug and 4-plug. Board jumpers are set to match, and on a 4-plug harness the plug with no matching connector stays disconnected.
- Link asks for a pinout compatibility check before installing, because similar models can share a connector with a different pinout.
- No onboard MAP sensor: the ECU reads the factory MAP sensor, or a sensor wired through the expansion connector.
- Electronic throttle is not available out of the box; Link says a modification is needed first. Contact us before ordering if you need it.
- It arrives with a base map that gets the engine started; that is a starting point, not a finished tune. Tuning is done in Link's free PCLink software on a Windows laptop, and the USB tuning cable is in the box.
Highlights
- Two knock inputs, with knock windowing.
- Runs the factory idle control hardware.
- Onboard barometric sensor for continuous altitude correction.
- QuickTune automated fuel tuning and individual cylinder correction.
- Switchable dual fuel and ignition maps.
- Two CAN buses for a dash or keypad.
- 512 MB of onboard data logging.
