Remapping advice needed - W211 5.0 V8

[Londonscottish]

Hi All,

Assuming my insurance company would be OK with it and when I can find the spare cash needed I'm tempted to go ahead with a remap.

I had a quick chat with DMS yesterday the broad pitch was that they like the V8 5.0 but believe that Merc have it in a very relaxed state of tune. A remap gives a much improved throttle response which in turn provides the car with a noticeable change of character. In terms of numbers;

- Power goes from around just over 300 bhp to just over 340 bhp
- Torque goes from just under 340 lb/ft to just under 360 lb/ft
- Marginally improved MPG

It's totally unnecessary in the big scheme of things but then a lot of fun things in life often are.......

Tell me why I shouldn't go ahead/suggest other options - eg has anyone used DMS or anyone else to successfully remap one of the these N/A V8's?

DMS are over priced and miss quote their figures, there is no way you will see 340 from just a remap.

You will probably see an increase of 21-24bhp and that's all you will get from a N/A engine remape.

Thanks BenzedUP

Any other thoughts from anyone else?

I'd agree with our good friend BenzedUP.

I also have to say that DMS were quite expensive when I enquired about mine.

Angel Tuning state 25BHP increase on an E500 and the cost would be more reasonable with them. Why dont you see about organising another group remap as a few people have been posting on the old threads saying they are interested in one. IIRC we had a couple of members with V8s in the last group remap.

They know you`ve got a rare car,so you must be loaded

Well I suppose DMS spend a lot on advertising and PR - full page ads in Evo every month, frequent press stories.

I find dms ok in price but I can get a discount from them......

But it is best to see what others can offer and then you decide

When I enquired for my 55, DMS quoted £795 inc vat (on rolling road if done on site) but at that price I ll probably go for Kleemann at £795 +vat and there is also one more company (evolve motorsport) very highly rated around the world and they are UK based so I ll be speaking to them as well.

There is of course for more money Renntech and MKB.

I have thought about this for my E500 also, so am watching this thread with interest. What interest me even more though, would be to have the exhaust note more like that of the 63.

I would defo do Renntech, Olly is now an agent, worth giving hm a call! Lopez has alot of Renntech goodies on his E55 and that thing is rapid. Also check out mbworld as the USA guys are nutters and do amazing things with their motors.

best of luck

Try West-Tuning they did my 55 and will be going there to remap my M3.

They are really good

Yeah I looked at the Renntech site when Ollie announced he'd got the franchise which sort of started me thinking - only issue is price - £1500-ish iirc.

OK ta

How about AMD Technik? think they have a site by Lakeside and another out west..

The figures do sound high for the car.

I remember when I was on the 'cough' BMW forum many 330d, 535d owners used DMS... and they seemed happy.


However and not being funny, but any of these remap companies with techs with a laptop would the outcome from all of them not be almost the same.

 

[Londonscottish]

Well my remap budget has just gone up in smoke - SWMBO got me to buy two vintage armoires for my new house over the weekend on ebay.

Cost? One remap each

This will have to wait.

PS took the car out a couple of times at the weekend and 306 bhp and 340 of lb/ft all present and correct.

Lazy throttle? Part of the character

 

[st4]

If you find the throttle lazy maybe a sprintbooster is what you need.

I personally wouldn't bother with a remap. Its forced induction cars that benefit the most from it.

The reason the 500 is in such a relaxed state of tune is for longevity, that engine will go on and on and on.

I didn't find it lazy until I spoke to DMS and they suggested a remap would sharpen it up. It's just a normal Merc throttle response at the moment - you have to really bury the pedal to access all the horses. Which is OK really as it just makes it relaxed. If I switch the garbox to Sports mode the whole thing comes more alive. But after a few minutes I always switch it back to Comfort anyway

Yeah and this is a one owner (before me) E500 with all the toys - must be one of the very best in the country. Probably be best to keep it stock and spend my hard-earned ££'s on regular maintenance to keep the history tickety boo.

You see, you should have bought a 55k in the first place
