EXPOSED! Diesel Tuning HORROR STORIES & How to avoid them - Blown turbos, & high EGTs - Expert tips!

Shauno heads to Ultimate Diesel Tuning to expose some pretty serious issues with unsafe diesel carpark tunes!
Car park or flash tunes can be fast, cheap and will make a difference to the way your 4WD drives, but here's why you shouldn't take the risk!
More power often means HIGH EGTs, more fuel and black soot, bad air-to-fuel ratios and a whole host of of potential big issues.
When you're getting your 4WD tuned, make sure you've got a professional making sure your intercooler piping, turbo, injectors and overall engine health is up to the task.
If you're chasing BIG power from your diesel 4WD, you'll need to consider reducing intake air temperatures by fitting a bigger intercooler, lowering exhaust gas temperatures with high flow exhaust systems, upgrading your injectors for more power and a whole lot more!
Chat to the experts at ultimatedieseltuning.com.au/ and see what the options are for your rig!

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.

[@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.

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.

Also besides emissions modern cars are tuned to within an inch of their lives so any increase in torque or rpm is playing with fire.

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.

[@Viperflame08]

I’m in SA and drive a 2000 3L patrol and keep getting told no one in SA dyno tunes them and that I have to send my computer outa state to be modded and have a tune uploaded onto it.... this always sounded similar to a car park tune to me and figured I’d just deal with limp mode and sitting behind slow drivers because I cannot over take them haha 😅

[@UltimateDieselTuning]

Yes that is the same as a car park tune Timmy. Find someone who will fit a Unichip to it & will custom dyno tune it from there.

[@alistairwhite2906]

Try MTQ, used them in Melboure on our old 3L Patrol in the past with great results. They should have a dyno over there too......

[@Viperflame08]

@@UltimateDieselTuning which is probably why they tell me my computer needs to be modded.... but every store that I have either called or spoke to online all said it needs to be sent outa state.... ECPT was the company most recommended to me.....

[@UltimateDieselTuning]

@@Viperflame08 you may have to travel interstate for this. We used to do them with Unichips - there is absolutely no need to send your factory ECU away at all. These days we only remap the common rail turbo diesel engine ECUs

[@Viperflame08]

@@UltimateDieselTuning thanks for the info. I’ll try an organise a trip to get it done when things calm down more.

With financial decision making like that Steven, I don't think you can trust yourself.

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.
