Diesel powered vehicles especially with forced induction we can achieve great gains in power and torque with no/minimal supporting modifications.

Some vehicles/engines will respond better to a tune with certain supporting modifications. Please contact us with any questions around this.

Typically the more support modifications on the vehicle the higher the gains in power and torque. If you’re unsure, we are able to make recommendations on suitable supporting modifications to get the best value for your money.

Fuel economy can be a difficult thing to quantify especially when you’ve just installed a remapped ECU and are keen to use the extra power and torque available to you.

If your driving style hasn’t changed from when you fitted the remapped ECU increases in fuel economy typically up to 10% can be achieved but is dependant on the car and driving style.

Generally speaking fuel economy won’t be that much better in the first couple of weeks, let’s call it the ‘honeymoon period’ when people like to drive harder than they normally would because of the extra power. After this period when driving styles relax and go back to how they were pre-tune fuel economy will usually appear better.

We aim to stay on the more conservative side of things especially when it comes to mail order tunes. Each car is slightly different and staying on the conservative side allows us to keep each car reliable without putting each and every car on the dyno.

With nearly 95% of customers purchasing mail order remapped ECUs due to not being local you can be sure that the process and tunes have been well tested and trusted over the years.

Over 7000 (as of 2022) mail order remapped ECUs have been completed since 2012 with complete customer satisfaction.

A mail order remapped ECU to suit your supporting modifications has been developed on the dyno and has been tested on numerous cars we’ve had on the dyno with the same/similar supporting mods to allow for some variation to show.

A remote testing group is selected and further variation testing to completed or non-local customers have the tune verified on the dyno by their local performance shop.

Once the tune is proven it is the sold onto customers that don’t necessarily need to have their car verified on the dyno.

We also offer dyno tuning for those customers that are local or wish to make the drive. We have customers drive to us from all over Australia.

Our mail order process is much quicker and easier than a dyno tune.

We are able to process orders efficiently to reduce associated costs so we pass these onto our customers.

Swapping over an ECU is a simple process and can usually be done in under 10 minutes by someone with basic hand tools and the knowledge on how to use them.

For specific fitting instructions please see the product page.

All send in orders are typically turned around in 1-2 business days.

Our loaner, exchange and outright orders are typically sent off within 2-3 business days from time of order or payment clearing for direct bank transfers.

We offer freight methods with Australia Post and TNT/FedEx which are selected during checkout. Once your order is with a courier we have no control over the delivery times.

Please contact us if you would like a current dispatch ETA.

If purchasing our send in option you will need to remove the ECU from your vehicle and send it in to us. We do our best to turn them around ASAP as we understand it can be difficult to have daily driven cars off the road.

If you’re unable to have your vehicle off the road look into our exchange, loaner or outright options (if available) or contact us to see what solutions we may have for you.

This all depends on how much power you want to make. A stock car can be remapped with great gains. Some vehicles we will recommend a manual boost controller as a minimum, especially on older vehicles, please see the product page for further information and recommendations.

If you would like more information on recommended mods please contact us with your details and what you want to achieve and we will be able to make a recommendation for you.

The amount of boost you can run will depend on many factors including the vehicle and engine you’re inquiring for.

Adding boost to a diesel without a tune wont do a whole heap other than lean out the vehicle and approach boost limits – potentially causing limp modes and boost cuts.

When we supply a tune/remap for you we will specify the required boost level (if using a manual boost controller – not applicable to most late model vehicles) the vehicle needs to run.

A remapped ECU will not change your gearing so your RPMs at certain vehicle speeds will not change.

Yes. We have a 2WD chassis dyno in house. We are also happy to work with another tuner local to you to provide you with one of our tunes.

You may also visit one of our dealers.

Most tuners have the ability to adjust/retune our tunes. There are a few vehicles that most tuners aren’t able to adjust which mainly comes down to knowledge and tooling.

These vehicles predominately revolve around the ZD30di Engine in the Navara and Patrol. We are one of few in Australia/The World that are able to tune these.

A remapped ECU is an ECU (Engine Control Unit) also referred to as a PCM (Powertrain Control Module) or ECM (Engine Control Module) that has had some of the values on it changed from what they were from factory.

An ECU contains many ‘maps’ or lookup tables that the ECU uses to know certain things for example how much fuel to inject given a certain throttle position and engine RPM. We modify these tables/maps much like the manufacturer would have during factory testing/tuning during vehicle development to make the car act and drive how we want it to.
