❓ FAQs:

Q: What is the methodology behind installing it as a piggy back vs as a standalone ECU on a 1FZ?
A: Installing the ECU as a piggyback retains the factory ECU for function of things such as sub tank, dash cluster, and other vehicle functions and instrumentation, we find this is suitable for most builds. Installing the ECU as a standalone allows for a fully custom install where the ECU has control over everything engine related, and transmission related

Q:  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.

Q: 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
