Q&A About Tuning Common Rail Diesels
What exactly is a custom dyno tune? & how long does it take? At Ultimate Diesel Tuning we are able to customise the data in your factory ECU, controlling all of the engine’s parameters such as boost, fuel injection, torque limiters and much more. This allows complete customisation of the vehicle’s standard/factory ECU (Engine Control
What Is The Process For Tuning A Turbo Diesel Engine?
Each vehicle is individually custom dyno-tuned via our tuners/engineers, on one of our in-house dynos. This calibration is customised with a lot of factors considered, including the age/condition of the engine; what the vehicle is used for (ie. city driving, highway driving, 4x4ing, towing etc.); & how the client wants his/her car tuned (what the
Is Custom Dyno Tuning Better Than Installing A “Chip” Into The ECU?
With mostly well-known rail pressure/untunable “chips” (that are unfortunately very common in the diesel market), generally what happens is that the chip is plugged into your fuel rail pressure sensor circuit, which interferes with the fuel pressure signal to give a false reading to the ECU, to fool it into thinking that the engine has
Will A Custom Dyno Tune Affect My New Car Warranty?
Under the Consumer Law, a dealership or manufacture cannot simply “void” the warranty of a vehicle. They can REFUSE warranty – HOWEVER, this can only be done if, via evidence, they can PROVE that the custom dyno tune/modifications were the cause of the problem. For your peace of mind, we also provide our own UDT
Does Good Quality Fuel Avoid Engine Soot Build Up?
I’ve heard that if you use good quality fuel, then your engine won’t develop soot build-up. Is this true? That is incorrect! ALL engines that have an EGR valve WILL develop a build-up of soot (carbon). Although continuous use of diesel additives/conditioners or using very high-quality diesel fuel can lessen the effect of soot build-up,
Get Your Fuel Economy & Performance Back!
Has your diesel engine done over 50,000ks? It is heavy on fuel? Does it feel sluggish & is it blowing excessive black smoke? Do you want to get your economy, performance & driveability back to how it was when it was new? Did you know that an Ultimate Diesel Tuning on-car chemical soot clean will
Clutches & Custom Dyno Tuning!
Is a clutch upgrade required if a custom dyno tune is carried out? Short answer: NO, not for most vehicles, but for some it’s a strong YES! A clutch is a consumable item that isn’t going to last forever. Much like brake pads do, it will wear down over time & require replacing or upgrading.
Reduce the Shock
Upgraded suspension Vehicle manufacturers are bringing out their independent front suspension (IFS) four-wheel drives with so little ground clearance. A little more would be great. As a standard vehicle will bottom out in the ruts even on an easy track to popular family beach and camping spots. This is something than can easily be solved
Cleaner Cooler Air
Advantages of Snorkel A snorkel, often referred to as a raised air intake, when fitted to your four-wheel drive moves the engines air intake from your airbox under the bonnet, to roof height. This has many advantages as described below: Less chance of water entering the engine when crossing rivers. Access to cooler cleaner air.
How Essential Is An Oil Catch Can?
Do I need an oil catch can? Oil catch cans are highly recommended for all direct injection engines. This is due to the small amount of blow-by that is present in a factory engine. This excess crank case pressure has been bled past the piston and the piston rings and into the crank case during
Stay Cool This Summer!
Intercooler upgrades An intercooler is an intake charge cooling device that is used on most turbo charged diesel engines. An intercooler cools the air compressed by the turbo, reducing its temperature and thereby increasing the density of the air supplied to the engine. There are two main types of intercoolers that are available. They are

- Daniel Colman
Highly recommended the guys at UDT Geebung rob and the team worked wonders on our 2011 ford territory way better torque transfer which made gear shifts a lot smoother they basically removed the turbo lag so over taking is a breeze now and the fuel economy blew my mind I did a test on the way there reset the trip computer and avg fuel economy was 8.9 L/100km after the team worked there magic on the drive home the same route which was a 1.5hrs drive the car only slipped away at 6.6L/100km could be believe it I was hoping to see a little saving like low 8s or high 7s but mid 6s is amazing can’t wait to hook the camper up see how the towing difference is thanks guys couldn’t have asked for a better result.
Nick JordanGold Coast shop- I had the ‘chemical soot clean’ done to my LC200 due to having 200,000 km. I only had the budget to do this process or a tune. I opted for the clean for engine longevity that they claim, and due to claiming better fuel economy and power.
Unfortunately no change in power or fuel economy whatsoever.
Good friendly customer service though. But a lot of $$ for unseen results. I think if UDT claim better fuel economy and power from their soot clean method I think they should back it up by showing you the specs before and after which they don’t. - Gerry Murphy
My 2017 Ranger has 70,000 kms on the clock and wasn’t running as smooth as it had been.
The guys from UDT gave the engine and manifold a good clean, fitted a catch can and did a UDT tune.
They were clear and concise about what they were doing, it’s benefits and the cost.
While it was there, they fitted bigger wheels, tyres and guard flares. They even had a small dent removed that I didn’t know was there!
The car now runs so much smoother, it has zero hesitation on acceleration and flies up hills. It’s just overall much better.
Thanks Rob and the UDT boys.Wayne CottonI had my 08 Jeep jku wrangler tuned and pre fuel filter and catch can installed by the Arundel workshop.
They went above and beyond to get every request I asked of them into my Jeep and at the quoted price and after the tune my heavy Jeep with 250k km feels like a completely new car I was astonished!!
AAA+ WORK GUYS WELL DONE - Adam Crew
2010 Ford Ranger tuned, desoot and intercooler done a month ago. Have done about 2000km since and so far so good. the car is an absolute pleasure to drive now. the only negative is that the intercooler kit you supplied has cheap and nasty hose clamps. you could do better with something decent like t clamps. I have had my intercooler hose come off 2 times already so I will now be replacing all the hose clamps. given the cost of the kit it's irritating to now have to change part of it. Only a small issue but goes straight to reliability.
Lance WellsVery happy with the customer service from Ultimate Diesel. My vehicle was in for a custom tuning and there were a few issues with my Turbo. The technician went out of his way and spent a few extra hours on it to try and give it the best possible outcome. Have rebooked in another service to recheck everything again at their request which was above and beyond.

The initial research to have my 200 Series tuned with chip and exhaust was pretty extensive, I didnt want to just throw money away and I wanted it done correctly.
I eventually decided to go with Ultimate Diesel Tuning and so glad I did. The team there were great to deal with and they discussed with me what to expect in relation to improvements to the vehicle.
I was initially a bit skeptical but after driving it for the first time after the work I was shocked. It feels like a completely different car. The power is instant there is no lag and is significantly more dominant than before the tune.
I havent had a long enough trip to be precise on fuel consumption but it is definitely reduced compared to previous.
The team walked me through during process and kept me up to date. I had an oil leak which I couldnt find which was annoying they found it and fixed this for me while they were doing the tune.
I would recommend Ultimate to anyone who is looking for a good reliable tune any day, I also intend on returning for all works I cannot do myself.
Very Happy
