Diesel Dyno Tuning

Our fully equipped Dyno station offers a custom Dyno Tuning service that is tailored to your exact level of desired performance.

Dyno Tuning measures the output of your engine. It provides accurate information about your engine’s horsepower, torque, and air-fuel mixture. Using the dyno’s data acquisition and engine function graphing techniques, you get a snapshot of the real-world performance of your vehicle


Dyno tuning is an excellent way to improve your vehicles performance and provide a more efficient and smoother ride. This process can help address common problems like difficulty starting, lack of power or poor fuel economy.

Here in FNQ there is no shortage of travelling to be done, whether its a road trip with the family caravan and you need more towing power, or four wheeling driving and you need that extra boost, we can help! If you are looking for top-notch performance, consider a custom Dyno Tune from Cairns Diesel Service to get the most out of your vehicle.

Dyno tuning is a process used to optimize the performance of a vehicle’s engine. It involves using a dynamometer ( we call it can dyno) which measures various parameters like horsepower, torque, and air-fuel ratio. During the tuning process, the vehicle is strapped onto the dyno, and the engine is run at various speeds and loads. The data collected by the dyno helps the tuner make adjustments to the engine’s parameters, such as fuel delivery, ignition timing, and airflow. These adjustments are aimed at maximizing power, improving fuel efficiency, and ensuring the engine operates within safe limits. We make changes and tests until the desired performance is achieved.

There is a number of benefits including increased performance, torque, throttle response and fuel economy!

One of the main benefits to ECU remapping is moving the power and torque further down in the RPM range meaning you access more power and torque earlier and with less throttle. Typically, we see improvements of 10-15% in horsepower and torque. Depending on the vehicle this can be slightly lower or higher. 

Another benefit that is commonly seen from ECU remapping is the elimination of any flat spots in the power and torque curve. It is common for modern vehicles, particularly common rail diesels to have a flat spot off idle which is demonstrated in the dyno read out below, the bottom line is the power and torque curves of the pre-run when the vehicle was delivered to us and the top line is after ECU remap.

We can perform a Dyno Tune on 99% of Diesel Vehicles. There are exceptions though, so if you think your vehicle might not be applicable, get in touch and we will let you know

When we remap a vehicle, we aim to optimise power and torque output of the engine within the safety margins of the manufacturer. We will never come close to reaching the limits of a vehicles engine, we guarantee it. 

Each individual person uses their vehicle differently and has different needs and requirements, we always take these factors into account when remapping any vehicle to match a vehicles performance to the owners specific set of needs. 

You don’t really need to prepare for a Dyno Tune but please ensure your tyres aren’t on the way out. The Dyno measures information by simulating your car actually driving, so the back wheels will be in use on the rotating belts. 

Every vehicle is different and in order to give you an accurate quote we would need to have a chat regarding the make, model and your goal with the vehicles performance. 

Not only will you see an improvement in your car’s performance after getting an ECU remap, but you’ll also see an improvement in fuel economy. That means you’ll save money on fuel costs in the long run, which will more than make up for the initial investment you made in getting your ECU remapped.

So don’t let the cost of an ECU remap deter you – it’s an investment that will pay off in the long run!

So my husband has been nagging for ages to get the car “tuned”. I thought it was a waste of money. Anyway we finally decided to get it done, I was sceptical it would make any great difference. Oh boy was I wrong. Our car is now like a totally different car. It’s so much quieter, changes gears so much smoother, has a lot more power, especially when towing and the fuel economy has improved. I now have more confidence in our car especially as we are on the road full time and need a reliable car. Well worth the investment. Thanks to Daniel & the guys for their friendly, prompt & reliable service. Now you can say I told you so.

Thanks to the team at CDS, they tuned my 80 series with amazing results, very professional and a pleasure to deal with. Would highly recommend them to anyone looking for any repairs or dyno tuning.

Purchased a new LC79 duel cab and was dissatisfied with the performance of the vehicle. Fist stop was CDS to see Travis and the team to see what they could do. A slight tune up and was a completely different vehicle. More responsive and power. Great service and advise and would definitely recommend them.
