Link G4X JZX100X Plug-In ECU, Toyota Chaser, Mark II and Cresta JZX100 1JZ-GTE VVT-i

The JZX100X is Link's G4X plug-in ECU for the JZX100 Chaser, Mark II and Cresta with the 1JZ-GTE VVT-i. The Link board fits inside the factory ECU case under the centre of the dash and plugs into the original loom, and it ships with a startup map to get the engine running before tuning in PCLink.

Fits

• Toyota Chaser X100 (JZX100), 1JZ-GTE VVT-i
• Toyota Mark II X100 (JZX100), 1JZ-GTE VVT-i
• Toyota Cresta X100 (JZX100), 1JZ-GTE VVT-i

Before you order

• Designed for manual-transmission cars. If your car is an automatic, contact us before ordering to talk through automatic transmission control.
• Compare the connector on your factory ECU with the header shown in the product photos before ordering.
• Link lists the VVT-i 1JZ-GTE JZX100 only; the non-VVT-i JZX90 takes the JZX90X (235-4000).
• Installation: the Link board mounts on the factory base plate inside the original ECU case. The case's centre bar may need cutting out and the slot around the header widening for cables.
• Electronic throttle runs from the board's dedicated E-Throttle expansion connector, which needs a loom (sold separately).
• On this unit CAN 2 feeds coolant temperature to the factory gauge and the A/C, and Link's install manual shows CAN 1 is not brought out to a connector. Dashes can still use the RS232 serial stream; ask us before planning a CAN device.
• 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

• Onboard MAP sensor: 4.0 bar absolute on older bottom boards, 7.0 bar absolute on newer ones, which carry a 7 bar sticker. A board jumper also lets a MAP and IAT sensor be wired through the factory MAF plug.
• VVT-i inlet cam control.
• Two knock inputs.
• Spare ignition outputs on the expansion connector for a direct-spark upgrade.
• With the factory air bypass valve removed, its wiring can run a boost control solenoid.
• G4X feature set: flex fuel, open- and closed-loop boost control, dual closed-loop lambda, engine protection limiters, CAN keypad support and a built-in trigger scope.
• Launch control, anti-lag, traction control, nitrous control, gear shift and paddle shift control, cruise control and a race timer with power management, plus 512 MB of onboard data logging.
