Re: Question for GP owners who re-mapped

If it's a dodgy turbo then it will eventually 'blow up' anyway, the remap will just make it 'blow up' faster as the map makes the turbo work harder, so it's more likely to blow up while your car is still in warranty.

Re: Question for GP owners who re-mapped

Theyre Garrett turbos aren't they? Renault have had trouble on their 1.9 DCi Engines because of these.

My parents Laguna had the first turbo replaced under warranty at 16,000 miles as it was leaking oil & i've since read about the turbos failing on Renaults where it can take the engine with it, so we just keep a close eye on the oil level & condition & try to let it idle for a few mins after a long journey to let things cool down gradually. It's now on 46,000 miles & had no more trouble yet so hopefully thatll prolong the life of the turbo abit. If it's the same turbos on the GP i guess the same treatment would help. Not convinced about these remaps tho.

I always let it cool... (and yes, its a variable vane turbo) simply by driving it gently for the last few miles home... hope it prolongs long life...don't really know if its ness, but I've had turbo cars for many years, right back in the old saabs, and they wern't watercooled, and had a habbit of blowing up if you didn't let them cool down properly......

as for garrats I thought they were the more reliable.... on the fabia vRS there are two types used, garatt and kkk, and its normally the kkk ones that blow on the vRS, not the garetts.....

i always have to drive pretty gentle by the time i get home as i live in me city centre with all the traffic you cant go nowhere in a hurry! So i dont need to let it idle or so for a minute before i turn the ignition off then?

Re: Question for GP owners who re-mapped

*bump*
Either :-

a) hardly anyone has had a re-map
b) hardly any GPS have suffered a turbo failure
c) those who have had a re-map and had a turbo failure rag the cars rotten and neglect servicing

Come on you re-mapped GPS owners let the rest of us know what to expect and / or fret about!

You know I'm more than happy with my AT remap, just over 6,000 miles remapped, averaging 46+ mpg with some spirited driving on shortish runs. Quieter, smoother, faster too...

Hang on, I better be careful how much I praise the Angel boys will only get called a lick ass, by your friendly neighbourhood moderator...I fear another infraction is imminent...

It's a bit of a strange one this Ffoxy and as you know this issue of reliability post remap has been going on for ever. I've covered 12,000 miles with my remap....I haven't had a single problem with the car apart from a non-related air conditioning glitch and a ridiculous Fiat dealer service department to contend with. The clutch is fine, I've had no extra tire wear, the fuel economy is great and most of all it's brilliant fun to drive if driven properly!

The bad news is that my turbo has recently started to whistle and whine more as I've stated in another thread. Some will say this is bad and some will say that non-mapped GP's whistle too so there's nothing to worry about. So, I'm not sure myself but I do worry about it. The only other big drawback of the map is the black soot that's left behind you when you really boot it. I hate that part which is why I try not to get to that point when having a blast.

For the fun factor and general efficiency of the car it's certainly worth doing...but for the long term I'm starting to have my doubts.
Thanks 1.8Stilo thanked for this post

Re: Question for GP owners who re-mapped

OK thanks to Sharkrider, Shropshirelad and Pezz175 for their input.

I do get a quietish kind of spooling up and down whistle from my turbo anyway, even driving normally, which turns into a pleasant pssssh at times of fun driving, I wonder if it was re-mapped before I got it, (it had 1,500 miles on the clock and half worn front Bridgestone tyres!)

So far no-one has actually admitted to a turbo failure in this thread, its really the servicing habits of the re-mappers I am interested in to try and piece together a "failure profile" if you like, of course taking note of daves statement about batch failure, but I cant find anything on the 'Net or other forums about that, the 1 exception being Renault.

The Garrett site I found imply its everything else rather than their turbos, but I guess they would say that wouldnt they....

Re: Question for GP owners who re-mapped

thanks pezz175 thats a great post... i am thinking about the remap! But personally will have to keep the car hold of the car for a fair few more years! I am thinking of a mild remap! To try and obtain a balance... if there is such a thing lol.

heres an explanation of the whistling noise you describe of the garrett website:

What is causing my turbo to sound like a sewing machine's whistle?
The "sewing machine whistle" is a distinct cyclic noise cause by unstable compressor operating conditions known as compressor surge. This aerodynamic instability is the most noticeable during a rapid lift of the throttle, following operation at full boost.


and then what compressor surge is:

What is compressor surge?
The surge region, located on the left-hand side of the compressor map (known as the surge line), is an area of flow instability typically caused by compressor inducer stall. The turbo should be sized so that the engine does not operate in the surge range. When turbochargers operate in surge for long periods of time, bearing failures may occur. When referencing a compressor map, the surge line is the line bordering the islands on their far left side.
Compressor surge is when the air pressure after the compressor is actually higher than what the compressor itself can physically maintain. This condition causes the airflow in the compressor wheel to back up, build pressure, and sometimes stall. In cases of extreme surge, the thrust bearings of the turbo can be destroyed, and will sometimes even lead to mechanical failure of the compressor wheel itself.
Common conditions that result in compressor surge on turbocharger gasoline engines are:
A compressor bypass valve is not integrated into the intake plumbing between the compressor outlet and throttle body
The outlet plumbing for the bypass valve is too small or restrictive
The turbo is too big for the application


check it out if you wana read:
http://www.turbobygarrett.com/turbob...nter/faqs.html

Although saying all that when i brought my GP 3 out of the 4 i test drove, none of them mapped all whistled! But only under load which is the same as my GP now! I think its more if the whistle is constant when driving and not under full load. Hope that helps

Re: Question for GP owners who re-mapped

I suppose the real question then to make it easier for those already re-mapped, bearing in mind 1.8Stilo and I are looking to keep our GP's for some time after a re-map is :-

Who has the highest mileage with no related engine issues after a re-map, and what is the mileage?

Wonder where Puntokris is etc... come on guys

Yes thats why I asked after him in particular, to get his take on how he drives and the service schedule he follows.

Wasn't your GPS an ex-demo from TJ Vickers? That would explain the excessively worn rubber!

@ Pezz - What years your car mate, I think the dodgy turbo's were fitted to 07 platers?
