Mercedes ECU re-mappers

[hawk20]

A good tuner will make claims they can deliver on, and charge appropriately.

A less good (?) tuner will claim the earth, charge bottletops, and deliver little.

Of course there are some who will claim the earch, charge the earth and deliver little!!

Well put. So who are the good guys? I assume Brabus are in amongst them as they appear to do a lot with Mercedes. I read somewhere in a thread that they are 'approved' by MB and have less/no effect on guarantee--is that so?

If you buy a Brabus enhancement through a UK main dealer then the warranty will remain in tact but will be limited to 60,000 miles (rather than unlimited).

If you buy from a Brabus agent, IIRC and broadly speaking, they will honour any repairs not covered by the warranty but found to be as a direct result of their modification(s). Not sure of the term - I would imagine for the period of the manufacturers guarantee on new cars, and 12 months thereafter. You'd need to check though.

There aren't many MB specialist tuners in the UK - www.brabus.de, www.carlsson.de and www.kleemann.dk both have a UK agent and are traditional tuners (ie not just chip tuning). A member here was dissapointed with the results from Carlsson though IIRC.

As a generic tuner www.dmsautomotive.com have a very good reputation as a generic chip-tuner. There are hoards of other generic tuners out there though, who often use an off-the-shelf map from the likes of Superchips, RICA and maybe even DMS, and some will tweak some parameters on a rolling road, but fundamentally based upon a core generic map.

I would personally prefer to use an established MB tuner - like Kleemann, Carlsson or Brabus - but all use piggy back tuning boxes, which I'm less keen on than modifying the chip. However all three are market leaders and must have faith in the concept.

Finally there are others worthy of mentioning like www.bbr-gti.com who traditionally tuned VWs have a reputation for new MINI but will do 'proper' traditional tuning too.

It is pretty quick.

Maybe its me then.

Suppose im used to my Supra which has over 500 Bhp.

The A200 Turbo is a super car, i have had a A200 Turbo before the C-class.

www.obdtuning.de claims: may b they have a dealer in the UK ??

I would take that claim with a very large pinch of salt. Seen so many threads here and in US where owners say they get nothing like the claimed improvement in performance.

Baffles me where you all think it is worthwhile in the UK.

Not many turbo diesels in the USA, they will be comparing normally aspirated engines, not much power gains to be had with them.
Only turbos can supply enough air to get significant gains with remapping.

Can anyone recommend a good Mercedes Remapper.

Wanted to get the Wifes A200 Turbo remapped

I had mine done by Angel Tuning quoted a 20 per cent increase after dyno my car was up by 9 per cent BHP. Was it worth the £250 - for the increase - not really.

Hot hatches - which are almost certainly built to stand the same amount of abuse as an A200 (probably more given the way it's likely to be driven) - can comfortably produce another 40-50bhp out of the factory. They're just as mild mannered to drive too albeit things like throttle maps may be more aggressive.

Plus if you're prepared to run the risk of earlier failure of the turbo and other gubbins, you can crank up the boost, and boost means prizes. I mean more BHP.

On a turbo diesel it is easy to gain power buy fooling the sensors to increase turbo boost and then injection. But this may quickly get compensated by the ECU when the compressed air temperature raises and the ECU starts protecting the engine. You would need to start changing parts, bigger gooler, bigger turbo etc. On another forum a C220CDI owner had almost 300 hp from his engine. This one had a completely modified ECU, not just some sensor tuning. Reduced engine longevity and a pile of malfunction codes may be a result from poor "chip tuning".

If I remember correctly -- Brabus DON'T recommend using their tuning kit on a car which has done over 18.000 miles............wonder why ??

The fact that MB reduce the warranty from unlimited to 60,000 miles also makes me wonder why???

What do they both know - thru experience - that other tuners don't??

My recollection too.

I suspect the other tuners do know. However Brabus being a big organisation can easily be held to account should an engine fail, and the owner expect some kind of recompense should they not impose a clear restriction that makes the increased risk of failure clear to customers.

Small outfits are untouchable by comparison - they could fold up overnight should the need arise to avoid any legal proceedings - as they have no legacy, infrastructure, commercial commitments, etc. They could then start up again under a different name, and away you go again.

Not suggestion all small tuners are irresponsible - although I bet some are - just able to play by slightly different rules.

I may be wrong, but, is it not the case that the car has to have done less than 18,000 miles to qualify for the 60,000 mile warranty? If over 18,000, I think they still fit but will invalidate the MB guarantee. So they will still guarantee 60,000 miles from new with the Brabus kit fitted.

Brabus prefer to mod young cars, you will find a lot of pack's they offer require extra inspection's, the replacement of certain item's or stipulate restrictions as the car's get older (in miles not years)

A member here was dissapointed with the results from Carlsson though IIRC

That was on my C220cdi. The Carlsson only kicks in after certain safety conditions have been met. ie engine is up to temp etc. Apparently mine was one of the 5% of cars that just wouldn't work with any Carlsson box, I tried 4 of them. I was told one of the safety readings was probably slightly out of its margins so the box would never actually boot up.

Funny how opinions change from forum to forum. On the TTOC everyone was all for remaps however it seems the opposite on here. Its probably due to the lack of choice of remappers!

 

[Bobby Dazzler]

Lots to gain on a turbo petrol though - good value mod.

Yep, The only way for decent power increase is higher boost. Easy on a turbo. I fitted a Knight Sports ECU on my RX7 with boost increased to 14 psi ( the maximum before uprating the seals ) With the exhaust it gave about another 70bhp!!

I understand some may have concerns over reliabillity issues. But, in reality full power is not used that much and then useually for short periods. Add to the fact that the engine has a generouse safety margine, I wouldn't have any worries about getting some more boost out of mine.
being a Kompressor though, the only way is the pulley mod combined with a remap - 45 ish BHP(?).

 

[bigmacplease]

I would have thought a supercharged engine would have got similar results to a turbocharged? Shame that I was planning on getting a remap for my C230!

Im guessing the pulley mod isn;t as cheap and easy as a remap?

 

[kjay]

Yuv already got 195bhp, yer jammy git.

On a supercharged engine the boost produced is governed by the size of the pulley's driving it, and so can't be changed through software alone like on a turbocharged car.

Changing the pulley's isn't difficult in the grand scheme of things, but they are incredibly expensive. You will certainly see a difference afterwards though.

 

[bigmacplease]

kjay nothing wrong with getting a few more I did have 265 before! I found another mapper that says 230bhp with a remap but from what your saying that must be a different 230kompressor to mine?

Thanx for the info bobby dazzler its nice to know a little more about superchargers

Sorry, a bit confusing. The figure was a rough indication for the 200K. You could well achieve better results from your 230K.
