Nissan GU Patrol ZD30di Remap Outright



This is for our outright service.

The GU Patrols have an immobiliser that keeps your ECU bound to your immobiliser module.

Please discuss with us first before purchasing this product to see if this option will work for you.

There are a few options available to work around the immobiliser for example:

  • Have the Immobiliser recoded by a Nissan dealership or locksmith
  • We can disable the immobiliser however in some model it can throw a check engine light. This option can make it hard to get a RWC and potentially void insurance if they are not updated that it has been disabled.

For other potential solutions/work-arounds please contact us.

The Process (How the outright option works):

  1. Contact us first to discuss your options with the immobiliser.
  2. Inform us of the model, transmission type etc of your car. Even better if you can get the model number from your ECU.
  3. You purchase this product from our store. Listing performance modifications during checkout.
  4. We prepare an ECU for you. If we don’t have an ECU in stock to suit your specific vehicle it may take 3-4 days for us to have one in stock.
  5. ECU is sent to you via an Australia Post Express service. If you require a different freight service within Australia or Overseas please contact us.
  6. Once received you install your remapped ECU following our instructions.

Please note that ECUs are not brand new. The price of a brand new ECU itself is more than twice the value of this item without remapping.

Prerequisites (Things required to supply you with a remapped ECU):

  1. Increase Boost: If you are running factory boost control (no needle and dawes valve – or equivalent) there is no need to do anything here. If you are running aftermarket boost control you will need to ensure this is set to run 20 PSI.

Custom Dyno Tuning

We are able to dyno tune your vehicle if you’re local to Albury to get the most out of it which will generally be more than the gains from a mail order tune as our mail order tunes are designed to be conservative/safe for the process. On the dyno we are able to health check your car and tailor a tune to suit.

Furthering our Mail Order Tunes

If you have performance mods that you want to make the most of we can tailor a tune for you. We will continue to develop more levels of mail order tunes as time, demand and local customers permit (we require vehicles with the same supporting mods to tune with) so if you have a certain requirement please feel free to contact us.

Stage 1 Mail Order Tune

We have currently developed one mail order tune to suit 20 PSI of boost and a standard or 3″ exhaust. This tune will suit vehicles with other mods such as an aftermarket intercooler and a high-flowed turbo but it  be may not be using those mods to their full potential.

Some benefits of our Mail Order Stage 1 ECU Remap:

  • More power and torque which results in:
    • Not needing to change down gears as often to maintain speed up hills etc
    • Easier/quicker overtaking. “Don’t need as much of a run up”
    • Less turbo lag on takeoff
    • Easier/nicer towing
    • Less stress pulling out onto busy high speed roads
  • A more linear and responsive accelerator pedal
    • Less ‘throttle lag’ so the accelerator pedal doesn’t feel as ‘doughy’
    • Less dead spots so its smoother to drive
  • Cruising EGTs are generally lower
  • Fuel economy increases. Most customers report on average an extra 100kms per tank
  • A disabled EGR system (no blocking plate required)

Power and Torque Increases:

The dyno graph to the right shows the general gains we see in power and torque from our mail order Stage 1 conservative Remap. The is recommended for people towing a lot and want something reliable/safe without getting the car on the dyno.



Before: Peak Torque of 293.7Nm at 2448rpm

After: Peak Torque of 426Nm at 1926rpm

Peak increase of 45% or 132Nm at peak torque. Peak torque has also dropped nearly 500rpm down from 2448 to 1926 rpm.



Before: Peak power of 71kW at 3742rpm

After: Peak power of 81W at 2574rpm

Peak increase of 15% or 10kW across the majority of the rev range Peak power has dropped from 3742 to 2574 rpm.

Examples of Modifications that will effect the tune:

  • Bigger exhaust
  • Intercooler
  • Non-Stock turbo
  • Bigger injectors
  • Water-Meth injection
  • Intake side (including airbox) on the higher power tunes
  • LPG injection
