If the airflow, boost and fuel pressure sensors are all manipulated perfectly in concert to stuff more air and fuel through the engine without the ECU noticing, and high octane fuel is used to resist knock it may be possible to fool detection, but it would have to be a perfect job to stay within the expected values presented to the ECU. However, what about the wastegate and fuel pressure duties, do they take over these outputs? What about longitudinal g sensor or wheel speed sensors which in concert with gear and throttle position or falsely low calculated torque? What about GPS data? Too many inputs and outputs to clamp, some of which will be CAN bus. Even with my limited imagination, if they want to detect they will be doing so. This shouldn't stop you tuning, but don't bank on them paying out a five figure warranty claim.

I am posting as the OP asked my opinion by PM.

The you have a comprehension issue.

Many? Nope, but that aside Ted doesn't have a 6.2 and this thread is about remapping

Carnut

Let's not forget, AMG's have hand built engines.

Littleted

And that was my view. But if anybody is watching the Aclass forums only just now, its been noted AMG actually tested the units and passed them as ok and within the thresholds of the engine. hard to believe eh, but its not AMG whos doing the Waranty but MB.

Lets see where that thread goes...

Here a snippet

Ill double check with Rebellion but as far as i know the tuning boxes were sent to AMG during development by Rebellion / Eurocharged to check they were safe and undetectable. The result was a clean bill of health.

Carnut

AMG are assisting a tuner to go undetectable so they can trick MB?

f1_fan

iTrader: (9)

Fixed that for you

Oh and stop using apostrophes where they are not needed.

Carnut

The point is that AMG may well make the best engines in the world but failures can still happen.

mrtheedge2u2

Majority of messages on this thread are about if a MAP can be detected or not and if that may invalidate the warranty. You then come along going on about how reliable the engine was. No one as far as I can read said the engines were not reliable.

I cannot wait to hear from you about where my comprehension issue is in this matter.

And as not to be completely off topic.....Ted, as always, your car, your money. No one is saying do not do it. They are just giving advice. Investigate properly, minimise any risks and enjoy the outcome of the car

And then two people come along commenting how RENNtech are basically lying...and how they wouldn't mess with it... my response was to them! Hopefully that clears it up for you

XDevil666

Ah man comeon, your asking a sales guy a question - they will of course say Yes!

how about giving AMG a call and asking them the same Question ?

as per one of there forum posts:

" Our unit is not traceable, we use ex AMG and Brabus engineers in the design "

they are selling there product on false claims, how can they be 100% certain that the programming used then is the programming used tomorrow on the ECU's?

you know that service that is due on your car? what if they update that ECU which records that "hidden" data which these EX AMG guys didn't know about

its like modding anything from phones, computers, games consoles, cars etc.

at the day 1 of release of any kind of mod, the people actively working behind that software buy one, learn from it and implement something to catch/block it.

if the ECU is encrypted and they cant get access to it, they cant see what hidden behind that lock and key

again your money, your car, your warranty - and hopefully its not a lease or something you need to give back at the end of the terms.

the guy is claiming as of feb 2014 to have sold 35+ units so if I was AMG they would be actively looking at detecting that mod to save on there possible warranty costs.

ignore that F1_Fan, that is the guy who trolls these boards about the 2.5 failure rate for years and then creates a thread saying he is looking to buy one and had a test drive in one, and it was too small to fit his signs in

f1_fan

iTrader: (9)

Do you specialise in making stuff up or is it just for my benefit?

Trolling the boards is not pointing out facts, it's telling people to buy a car that has a known issue and pretending the issue does not exist like you do all the time.

Or how about when you accused a couple of posters (me being one of them) of arson.

..... edited as what's the point?

Littleted

guys im with you honestly,

I did a post in laymens terms on the site asking kinda what John said.
If the 0-60 time suddenly becomes 3.8 does the car log it, in a way like Gs to flywheel, or turbo pressure etc..... unsure.. Im sure the values MB stick for 360 may creep forwards.

I don't know Mappings or how they work, but what you all know as well as me is Revo and others out there including DTUK do this PiggyBox and it works and people use it and get serviced.

I myself had a brand new insignia and bought a DTUK box it blew injectors in 10 mins, car went like a rocket for 9 mins LOL.

I took it off and Vauxhall fixed it. I returned unit to Andrew at DTUKL saying it doesn't work. OK its a Vauxhall so diff league, but these boxes exist and lots of A45 users are having cars serviced fixed without detection.

So either a dealer doesn't go deep enough to detect YET!!! or they are undetectable..

Either way its done now. I,ll report back if and when it gets serviced and the outcomes

All I need to do now is befriend the service manager at MB and job done LOL

XDevil666

Yes I made it all up

I never pretended the issue doesn't exist, just not 1 person on this forum with an engine issue on the 2.5 can answer all these quotes as no:

>Engine rev limits being constantly exceeded due to over speeding
>Vehicles being un-officially modified outside the design brief of the engine (unit is designed for around 300 BHP or 330 BHP in the case of the STI 330S, not more)
>Track use (racing, time trials, rallying etc)
>Incorrect maintenance procedures, causing engines to be run with insufficient or contaminated lubricating oils
>Use of incorrect fuel grade (RON97)
>Unofficial "grey" Imports of undetermined specification, ie. not supplied by Subaru (UK)


arson? I don't even recall what your talking about - but lmao, I think you have issues, we have gone from talking about warranty to you flipping it all the way down to me talking about arson? Clutching at straws much?

Stop trying to dodge around the subject

Its about reliability of the AMG engine should he choose to remap it.
You're the one banging on about AMG being in a different class to others - don't worry blah blah blah.

While AMG are in a better state than most engines, the brand still has suffered engine failures.

f1_fan

iTrader: (9)

Of course you don't

Oh yes and you seem to fail to mention the question I asked was about a 2.5 WRX whereas the failures generally seem to be 2.5 STIs... which is why I asked the question as well you know, but of course that doesn't suit your agenda.

Talking of straw clutching your little list of reasons the 2.5 has failed makes me laugh. All things people do all the time with the 2L STIs and have significantly less issues!

Dress it up however you like it, but Subaru dropped the ball with the 2.5 STI in particular.... and you still like to tell us all how great they are. More fool you.

OK enough on this as it;s way off topic. Start another thread in General if you like and give us all another blinkered preaching, it's been a few days since your last one.

mrtheedge2u2

Does something that voids warranty e.g. remapping void the warranty as a whole i.e. if the car started rusting in 5 months and they found out you had a map would they not sort it out for you?

As someone touched on today, what is undetectable today may be detectable tomorrow.

Littleted

no it doesn't, the guy who was questioned by MB still had the turbo done and they still cover him, but I bet if he has an engine issue that could be a direct result of the box, then they wont do it....

the turbo was a recall

Littleted

FYI the connectors that need swapping are as follows

manifold Air Pressure
Throttle Connector
Camshaft Position sensor
Boost Sensor.

XDevil666

so there you go, you finally have said it, your issue with the 2.5 is you cant mod it to the same reliability as the 2.0l

but how about I throw a ball here and say - you can!! just modding it safely requires forging the pistons as an initial safe point!

and please don't state : yes but pistons would cost £Xxxx, when your advising someone to mod a 40k car with a £2000+ box which fools the car in to increasing power lmao

XDevil666

Yes its a shame, but the guy is obviously still under warranty and with record sales 1 in whatever thousand sold is a good percentage bracket and if this engine is the same as the hawk, fix will be like a walk in the park for them

pretty cleaver thinking really of Subaru as the costs will now be so minimal for that engine as its been in the wild for a long time

on a side note **** apple! - bought the 5S last week and had to get it replaced today due to a hardware fault which couldn't be resolved via software

Littleted

your point is what ? we know the turbo was faulty batch ? hence the measurements. all sorted now... not masked like Subaru

laughable from an owner who's lack of research before buying his own car led to him owning one of the least reliable engines produced in modern times.

I know its a lot of money to Brabus but will they not offer some form of warranty or are they just pricey due to the name?

Littleted

it keeps your Warranty Steve.. if done from factory, it diminishes should it be done after and has to be done under 6000KM
