• Toyota Landcruiser FZJ105 Automotive and Manual
• Toyota Landcruiser FZJ79 Manual

Included in this package is,

• Boost Control Solenoid 3 Port 33Hz Thread: 1/8 NPT

Why use this package?

• The most straight forward solution to tuning your turbocharged 1FZ is to utilize a Haltech Elite ECU as a piggyback, keeping the factory ECU integrated into the car.
• This allows factory functions to stay operational while the piggyback ECU controls fuel, timing & boost – On automatic Landcruiser’s, that also means leaving the factory ECU in control of the transmission shift points as it should from factory.
• We have created this package with an Elite 750 ECU and the required sensors for tuning.
• Many of the 1FZ-FE Landcruiser’s turbocharged and tuned in-house at HD Automotive use this exact setup.

How is it fitted?

• The Elite 750 comes with a plug and pin kit allowing it to be wired into factory ECU.
• The ECU comes with a Haltech diagram and will have to be wired by either an auto-electrician or yourself.

Can I add more sensors and displays?

Yes, additional sensors and displays can be wired in the ECU such as,

• Oil/Fuel Pressure
• Oil/Fuel Temperature
• CAN Gauges/Displays

Important notes,

What is the methodology behind using a piggy back ECU on a 1FZ?

• Retains the factory ECU for function of things such as sub tank, dash cluster, and other vehicle functions and instrumentation,
• Price – we find this package is suitable for 90% of builds around the 350-400HP mark.

Can you help me wire this in over the phone? 

• We cannot provide extended support when it comes to wiring these in yourself as a DIY installer.
• There are simply far, far too many variations of ECU, different builds around the world, different wiring, etc. for us to support every single installation.
• So, when it comes to providing a 1FZ specific diagram, it is not reliably possible for us to do this. The Haltech diagram is provided offering full explanation of pins and pin outs of the ECU.
• A level of experience or willingness to learn is expected on you, the user, to undertake prior or during fitment.
• We love helping as much as we can, but this is a generic kit provided with an ‘all you need’ approach to the parts supply. We are not auto electricians.
