Description
The FZJ100 Link (TFZJ100X) is a G4X-platform plug-in engine management system designed as a direct factory replacement for the ECU in Toyota Land Cruiser FZJ100 models equipped with the 1FZ-FE non-VVTi 6-cylinder engine. It delivers complete control of fuel, ignition, boost, idle, and auxiliary systems while using the original wiring loom and ECU location for a clean, OEM-style installation — no wiring alterations required.
- Supports both 3-plug and 4-plug OEM wiring harness configurations
- Up to 6D fuel and ignition mapping with individual cylinder correction
- Sequential fuel delivery with staged injection support
- 5D boost control with three switchable boost tables
- Motorsport features: antilag, launch control, and flat shift
- Closed-loop cam control (up to four cams, independently controlled)
- 512MB onboard data logging memory
- Real-time selectable dual fuel, ignition, and boost maps
- Knock control with windowing
- Compatible with manual transmission only
E-Throttle capability requires a hardware modification. An XS Expansion Loom is available separately to add additional inputs and outputs. The ECU is tuned via Link’s PC Link software over USB or CAN.
