General Remaped Multijet Blown Up

[abarth_178]

I think the highest tune of the 8v Multijet is 130 bhp within the Fiat group. Alfas use the 8v but anything tuned above 130 gets a 16v unit with different turbo/clutch.

yeah thats what I thought...

Can you give us an update on your situation rptbu....

just to give an opposite view to maybe set some peoples minds to rest, you can map your car and get reliability... mine was mapped at 4,000 miles, and I'm up to 60,000 miles now, and everything is fine. everything still works "as new", turbo, clutch, gearbox ect..... my car has been serviced every 18k as fiat suggest, using the proper oil..... its driven "normally" from cold, and I never thrash it before turning off....

I've known many people with standard cars who have had turbo failures before 60k (before 20k in some cases!) and this would suggest it may be more likley to be a "natural" turbo failure than anything to do with a map....

but then I haven't even needed to change my front brake pads yet, so maybe I drive gently

If the OP is genuine, I feel for you, maybe a second hand engine from a scrapyard would reduce your bill? let us know what you do .

180bhp - turbo blown twice......

I'm a little bit worried here. My 1.9 mjet recently dumped all its cooling due to a split in the hose.

Shortly after I realised that my turbo was whining. It had blown.

I had it replaced (warrantied) and have driven about 50 miles, when the new turbo started to whine.

Is this down to the fact that the car has been remapped. Will it keep happening, or is it just me being unlucky with two ****e turbo's? Or is it something else?

I'm starting to think this engine can't handle 180bhp.... I'm also starting to worry about the questions I'll be asked when I go back to the dealer????

You'll get loads of replies and questions on this....

How many miles ago was the re-map done? Oil changes done on time or before? Did you rag it or drive it with empathy?

Send your ECU to Red Dot by Post and they will re-apply your old map I think.

Your Post will open up a world of pain again....

Re: Red Dot remap - 180bhp - turbo blown twice......

just unlucky with the 2nd one, the first one will be down to the coolant all being gone. how do you run the car, do you do the let car run a bit before driving and after driving thing that you should do on a turbo car?

 

[Hellcat]

Re: Red Dot remap - 180bhp - turbo blown twice......

If the 2nd has gone within 50 miles that suggests a faulty replacement part.

Re: Red Dot remap - 180bhp - turbo blown twice......

If my turbo goes i want to have a "Fiat Fourm party", with a cake and hats and candles and everything, like a birthday bash. hopefully all will attend and we can dance into the small hours.

I've gone over 140mph (not sure exact speed as the needle was off the clock) in Germany (obviously). Not sure if that affects anything but it was fun.

I've not changed the oil yet. I never let it run idle after driving long distances although I do have to come into town and drive at 30mph for 5 miles or so before getting home.

where are you guys getting that quote? i dont see the original post?

Post 110 by T Beany.... its from one of chunkthefish's earlier Posts when his problem was developing its coolant leak.....

"Not sure if that affects anything but it was fun"

i would say it does.

Not sure where my post dissappeared to... but here's what I wrote.

Anyway thanks for your replies.

It seems as though I've been a bit unlucky.

However, I had the remap when car had 200 miles on clock.

Drove to around 4000 miles and then coolant dumped.

Turbo blew straight after this.

Then a new one was fitted and I've done 50 miles and it's gone again. I didn't even get a chance to floor it in this time - just normal day to day driving in town conditions.

I don't thrash it cold. I always let it warm up before flooring it. I keep revs over 2500+ before flattening the throttle.

140+ is fine surely?
Anyway - aren't engines designed to operate at maximum revs. My friends a 1st engineer on huge power yachts (jammy git) and told me this was the case when I was asking about engines once. Perhaps he was talking about ship engines not 1.9 multijets....

No is the straight answer, not floored all the time, not allowed to warm down after a run, not to have oil chamges neglected and ragged / thrashed about.

Do that to most standard cars and the result might be the same, but you had a coolant loss failure and probably a dodgy turbo replacement or even a botched repair.

Treat your car well, use its extended performance wisely and it will reward you, but most of all dont neglect it, check and maintain coolant and lubricant levels / quality and keep on top of servicing. Its not hard....

Think of the re-map as pushing the design and performance limits closer to the edge of their design spec but not beyond. In a perfect world 2 turbos would be preferable to one at the power outputs after a re-map so be considerate.

 

[chunkthefish]

I see your point but I'm not some nutter who thrashes there car at every opportunity.

I went to top speed in it once (ok twice) but 140+ isn't something I'd be able to do again, unless I went back to the autobahn.

I never push the revs over 4200, and I'm quite careful to not floor it when the revs are low.

I didn't think Oil Changes were necessary until 18,000 miles or 12 months, which ever comes first.

When am I supposed to change the oil?

Thanks for your help.

No need to go to 4,200 rpm, no power or torque there to speak of.

When you uprate the engine performance you shorten the service parameters to accomodate that, 18000 miles is seen by FIAT as OK on the original cars spec, you changed the spec so you need to shorten the service intervals, even if its just a filter and oil change, a good look over the hoses and coolant levels, and a check of the brakes, a short service if you like.

Yes remap's increase boost which then increase's heat which then increases the pressure in the coolant system so you need to keep an eye on that coolant even more now!...
