Our approach

How we do the work

01

Health check

We confirm the vehicle is mechanically sound before tuning begins.

02

Dyno tune

We run the vehicle on our Mainline dyno and adjust the calibration.

03

Verify

We re-measure to confirm the result is safe and repeatable.

FAQ

Questions, answered

What is remapping?

When a manufacturer develops a new car, truck, bus or machinery they have to take into consideration all of the conditions it may be subjected to in all of the regions/countries in which they intend to sell this model, This means that instead of optimising the Engine Control Unit's (ECU) program or 'map' solely for the best performance or the most fuel efficiency, manufacturers must compromise the map to account for these potential differing operating conditions. When we remap a vehicle, we change the parameters inside the factory ECU to best suit how you use the vehicle. The maps that we adjust may include fuel pressure, boost pressure (on turbocharged applications), ignition advance and throttle pedal control among others.

What are the benefits of remapping?

Remapping can improve the engine's power and torque figures, sharpen the throttle response, widen the power band, and most importantly, reduce fuel consumption.

How can remapping affect fuel consumption?

A tune suited to your vehicle and its use may improve torque delivery and reduce the need to downshift in some driving conditions. However, fuel savings are not guaranteed. Driving style, towing load, tyres, modifications and operating conditions all affect fuel consumption.

How does remapping reduce fuel consumption?

Extra torque at the bottom of the rev range means you will require less throttle input to maintain highway speeds, allowing you to drive in a higher gear at a lower speed so the engine isn't straining as much. This also helps significantly when the vehicle is fully laden, towing or driving on gradients.

Is remapping safe?

Yes, it is a completely safe process as it gives the engine the performance it would have had in the first place before the compromises were applied to the original programming, We do not remove any safeguards and all of our tuning is done on our Mainline dyno to ensure that the remapping is kept inside safe limits.

Can you reverse a remap?

Yes, the software itself is 100% reversible.

Is remapping better than a plug-in tuning box?

Yes! Although many options exist for purchasing plug-in (non programmeable) tuning boxes, custom remapping, tailored to your vehicle, is undeniably the better option. A tuning box sends false sensor values throughout the complete rev range, which tells the ECU that not enough fuel is entering the engine. The ECU then overfuels to gain performance, which increases fuel consumption. The performance gains that can be made with a plug in tuning box come at the cost of high emissions, higher engine temperatures and general engine abuse. Over fuelling can also result in bore washing which will dramatically reduce the life of any engine.

How much does remapping cost?

Remapping is carried out on our Mainline dyno and starts at $1350, depending on the vehicle and your desired outcome. Mechanical pump tuning is also completed on the dyno and this starts at $750.

What vehicles can you dyno tune?

We tune a range of diesels and 4WDs. Tell us your make, model and any modifications and we'll confirm what's involved for your vehicle.

How does the dyno process work?

Several steps are involved in the dyno process. Technicians start by running your vehicle on the dyno to establish its current performance metrics and to give them a baseline for measuring improvements, Once the baseline data is collected, technicians can make precise adjustments to various engine parameters. Technicians alter things like fuel delivery and turbo boost pressure to maximise gains in real time. After the tuning, the engine is run on the dyno again to confirm the improvements and ensure that the engine is operating safely and at its peak performance.

How long does a dyno tune take?

It depends on the vehicle and the scope. We'll give you an idea of time once we know what you're bringing in and what you want from the tune.

Will I receive a dyno report?

Yes, each customer receives a printout of their dyno run, which shows their baseline run against the final tune so that they can compare the before and after for power, torque, boost and air fuel ratio.

Can you tune a vehicle for towing?

Yes — towing is a common reason people bring vehicles in. We tailor the calibration to how you use the vehicle, measured on the dyno.

Does tuning affect my warranty?

Warranty implications vary. We'll discuss this with you honestly before any work — we won't make claims we can't stand behind.
