great tip. Been a tech for over 15yrs and always good to see people pointing out the smart choices.

[@used2go]

Iv done plenty of diesel road tunes. I log using data from software like Techstream both before and after remapping. I do a general health check pre tune as well. I log Air fuel ratio with an Innovate sniffer. I also hook up a temp boost guage. To confirm what the map sensor is reading is accurate. Not all carpark tuners are equal. My files are prepared by professional writers and can be changed as many times as I need. My transmission files are also custom designed. I use a smoke maker to check for manifold and plumbing leaks. When I offer optional dyno hire for the extra dollars people opt for the road tune 9 times out of 10. I have also had to retune vehicles that ultimately had been to big dyno tuners and were suffering from overfueling and reliability issues.

[@yjkader]

You said it yourself. A ‘road’ tune implies it has been tested/dialed in, and is different to a ‘car park’ tune. They specifically gave the example of loading up an off the shelf tune without any testing, whatsoever and sending it. They’re referring to the ‘chip’ tunes sold by the likes of Elite Drive and PPD.

Hello, i have a a6 2.7 TDI from 2006 the 180HP 380 NM variant, took it to get a stage 1 tune, paid for dyno runs before and after the tune, the guy that did it said it made 227HP and 480NM, the tune was done at like 190.000KM, after like 8 months and at 208.000KM the vehicle failed going uphill and giving it a bit of gas to 2.000RPM so i can change gear and it failed, engine started shaking and stuttering and making something like a knocking sound, like an injector wasn't putting the diesel properly and it was just leaking it in the cylinder also it literally felt like it wanted to get out of the engine bay, wrote the the guy that tuned it said there is nothing wrong with the tune, didn't even want to look at the car, no black or white smoke out of the exhaust, no engine error codes after running VCDS, so i took to a friend he sent all 6 inyectors for testing and said 2 are not good but they can be repaired, i accepted to have the injectors repaired cost me 550 euros with testng and everything, car started working properly but it kept doing the knocking noice at inicial pick up, after it build a bit of rpg like above 1.800RPM that noice dissapear, feels like its not delivering either properly fuel or something like that, so i removed the tuned after arguing with the tuner, after 2 days of using the car noice dissapear, i was like okay lets do the tune again, paid the same guy to just put the sme tune on, 6 moths later same issue, this time i took injectors out myself, sent for testing, all turned out to be okay, car again does that wierd knocking when you initially step on the gas and goes away, can this issue really be from a bad tune and this dude is just asking too much from the injectors?? I have no idea what else it can be.

Big tip: change the rear drive shaft at about 100K, if you have one. I have a 5 litre, twin turbo, V10 Touareg, 355 awHP and 960 Nm of tractive effort after a proper dyno. I have Hi/Lo and a centre knuckle. Dynos monster the drive chain - just watch the snap to max RPM and sudden taper. Surprisingly, the Audi drive shafts are the largest for VW and Porsche. I replaced the front drive shaft by 120K. Dynos don't measure torque, they measure tractive effort at the wheels.. Torque is measured at the fly wheel/crank interface. I'm an overlander with a 1725 Kg camper trailer. All is on song.

[@UltimateDieselTuning]

Do you mean driveTRAIN? The taper at higher RPM is simply the standard turbo running out of puff, dynos do not put extra pressure on drivetrains. Our dyno can & does measure torque in Newton Meters, at the wheels.

[@UltimateDieselTuning]

Hey Troy. A custom dyno tune won't void warranty mate. In the case of an engine issue, then the manufacturer must prove, with sufficient evidence, that the tune caused the issue. They cannot just void the warranty. Tuners should have their own warranty too, like we do. Please give us a call on 1800034373 for further information on this.

[@djnmv]

Someone I know had issues with their engine after a tune, he then got stuck in the blame game between the manufacturer and the tuner and never got his repair bill covered by either of them. Neither would put anything in writing either. He said he wouldn’t do it again.

[@UltimateDieselTuning]

@@djnmv we can see how that would happen. Generally speaking you need to go above the service advisors & service manager & get a case study done. That is when you'll find it'll fall in the customer's favour. If, of course, it wasn't the tuners fault. We have been through this, only a handful of times, & have always come out on top. We step in for the customer & get it done. For example, an injector failure is one of the most common issues woth common rail turbo diesel engines & that will happen with an untuned engine too. Every manufacturer has replaced thousands upon tens of thousands of engines due to failed injector/s, which is a component failure.

Just needs to have a pre-tune inspection carried out (as do all cars) & then if all is right, if you have no soot in the engine, then it'll be fine to tune. We'll just be more conservative with the tune, due to the higher k's on your engine.

Boost tee and turn up the fuel 👌🏼

Is there any different between a diesel tune and a petrol (gas) tune that would be relevant?

[@imzackson]

there's about 278 their entire different animals

[@UltimateDieselTuning]

They are pretty much completely different Dylan

[@SamDrives]

So what about car park tune on a brand new 4x4? They prolly won't have any existing issues so I reckon it might be safe?

[@UltimateDieselTuning]

Definitely not! A car park tune is NOT suited to your actual engine & your driving conditions.

[@trendysoil6373]

Sounds like a pretty good way to create issues. Dyno tunes don’t void warranties but a ‘car park’ tune would likely void warranty and as mean as this sounds..so it should.

What are your thought on turning a n70 because they seem to crack pistons?

[@mohammedmuzakkir9803]

Maybe need bigger injectors

[@johncallus4184]

Mate i own a 08 n70 315k on it running perfect had a tune, as long as injectors are in good condition in spec you can get a read out at any diesel mechanic and egr is clean get a egt and boost gauge hooked up

No dramas. We have tuned thousands of N70 Hiluxes & 1KD Prados!

I took my 80 series with a 1hz to auto care in Mtgambier to get a dyno an tune .. 5 months later they tell me my injectors fuel pump valves etc are fucked so I had to replace them 5 grand later an they put it on the dyno an blow my engine !!!!! NEVER GO TO AUTO CARE IN MTGAMBIER

damn that sucks. have to be careful with the 1HZ very good engine but they don't handle lots of fuel well easy to blow them up even if a bad tune doesn't blow it up it can shorten engine by a lot.

yes Berrima diesel

[@beejaytee]

Always thought lean = heat. Is it different for diesels?

[@UltimateDieselTuning]

Yep it's pretty much the opposite

[@rlaxton666]

I have a 2012 Prado 150 3.0 Diesel with 115000km that is using way more fuel than it used to, when new, I used to see 9l/100km, now I am lucky to see 13l/100km. It probably did not help that the vehicle basically went nowhere in 2020 (I think that it was the same tank of fuel through the entire year). I am thinking a full soot clean, possibly injector clean and tune might be worthwhile. What do you reckon?

[@UltimateDieselTuning]

Yes absolutely mate. One of our on-car chemical soot cleans will do it wonders, plus a custom dyno tune by us to suit your engine/car & what you use your vehicle for! Expect awesome gains in power & torque, plus an improvement in fuel economy.

[@brendondick1198]

Hi i have a 2018 d'max, wanting to get a dynamic tune down the track so I was wondering if there is anything that 2018 d'max are prone to having issues having before I look at getting it tuned?

[@UltimateDieselTuning]

Just ensure that the intake is free of soot mate then she'll be right to be tuned!

[@GABTICO94]

Do you need to do oil changes more frequently after this? It the the auto gear box at risk from having more power? Or will the clutch pad last less?

[@UltimateDieselTuning]

No you don't. And no, no risk to an auto trans. Some manuals will need a clutch upgrade prior to tuning - like the 70 Series Cruisers, Hiluxes & Colorados.

[@GABTICO94]

[@UltimateDieselTuning]

Yes they are great engines

[@RGF56]

Lost me at 4.15 when you said you leaned it out and reduced the EGT's . Leaning usually raises the EGT I thought . At least it does in piston engine aircraft when you lean the mixture to peak EGT then run it rich of peak .

[@UltimateDieselTuning]

Diesel tuning is basically the opposite to petrol mate.

[@hillsidemotorsport7736]

Opposite for diesel engines. Richer equals cooler.

[@anthonysmith9057]

So if there’s the ‘free’ horsepower just sitting there why did the manufacturer not tune it this way? They aren’t going to make a car less powerful just to support the aftermarket industry. So what other aspects of the motor are compromised when you retune like this? Are your tunes tested to ensure they still meet emissions regulations? Or is that the next generations problem?

[@ianthebarefootwoodworker516]

They do it to meet emissions, variances in batch processing engines, longevity for the warranty period and other manufacturers requirements.

[@EnkeiTenjin]

Manufacturers tune their engines usually so they can warrant them. They want to be replacing as little components as possible, in turn spending less money in aftersales support. Also, due to the massive variance in fuel quality, a baseline tune must be able to run the engine in safe parameters regardless of what batch of fuel is put in the vehicle. Again, want to spend less on fixing a customer's car do to uncontrollable circumstances, which is totally understandable. Another big thing is emissions. They must achieve below a certain threshold of pollution, and typically 'detuning' an engine means lesser output of power, and lesser output of co2 emission. Factory tunes are always worse than what an experienced aftermarket tuner can provide in terms of driveability, fuel economy, and reliability.

[@danejohnston4887]

Hey I’ve got a 2018 76 series an was thinking about getting a tune! I tow a van and have heard that it’s worth getting a heavy duty clutch with a tune on a 76. Is that true? and is it also worth getting a bigger exhaust also? Was under the impression the bigger exhaust wouldn’t do much power wise being a DPF model car? Cheers 👍🏼

[@UltimateDieselTuning]

Yes, abolutely you need a clutch upgrade with a 70 Series Cruiser. The factory clutches are too weak to handle the huge gains in torque that will be achieved with a custom dyno tune! Exhaust = yes on a pre-DPF model & not really beneficial on a DPF-back model.
