Re-Map or Tuning Box!

[johns E350]

I would question 290 bhp , it's more like 270ish.

I have discuss remapping my car with several tuners one did not get back to me mentioning no names (Acid) all say they can take my 350 CDI from 231BHP to over 300BHP and the prices vary from £299 to £460 I am definitely going to have it remapped but just don't seem to get round to it.

I an recommend AMDEssex and yes it's just over the QE2 bridge but all their remaps are bespoke all done on a rolling road you get before and after prints and have great after care ( friend has a rs6 went to 750BHP and nr 750 ib or so torque ) after letting it settle in he thought is was a little hesitant took it back in and was sorted at no extra cost. Many I know have had there ST Mondeo's done and can't say a bad word about them !

I had a reply from a tuning company saying my engine (231bhp) has the same 265bhp block ,but that's not true so when they did say they could get my car to nr the 300bhp I declind I would say 265-280 bhp max !!!! After all the gearbox is rated at 750Nm and getting to the higher bhp would give you very close or over the limit that mercedes recommend for the std 7g gearbox

Im not so sure about that, Depends if its tuned for more BHP in sacrifice of Torque, or the other way round.

Just because you have a large increase in bhp it doesnt always follow you have alot more torque.

 

[KeithJG]

So.... reading through here the 290 quoted by Celtic maycome out at 270bhp but in any case the max. torque quoted will still be within the safe capability of the 7g box if 750Nm is the limit.......


I am in the same mind as @johns E350.......i can pay £295 at Celtic and they come and do the map or i can go to Chiptuners at Ipswich for £200 + fuel from Dover!........just don`t know what to decide ........think i may try AMD Essex?

Gav....what would you do?....give us an idea!........ChipTuners seem more realistic "Expect gains of 50-60+bhp with around 80-100 nm torque with better MPG 2-8+"...also i may get a free cuppa from you if i visit!!

 

[johns E350]

That is also my dilemma I live in Northampton so Ipswich is a long round trip. Celtic tuners will come to me but my worry with that is the ECU has to be removed from the car I am not sure what they do to it but can it be done outside my house do they plug the ECU into a laptop and rewrite the software any ideas.
Thanks

all i can do is go on my experiance, Chip Tuner's down loaded the vehicles original map and saved it, then prepared there map and when finished uploaded it to my Car again through the obd port.

I havent had the car on the rollen road but it pulls harder and smoother thoughout the rpm and the car doesnt run out of puff at 4,500 like it did before. It kept with a friends 252 bhp manual 850 t5 which are quite alot lighter so the power has deffinatly increased, mpg also improved.

Celtic Tuning i was impressed with the speed of there reply, and there Money back guarentee plus the coments from other people on here who have had there's done.

AMD ive heard good things about to and are alot closer to you Keith. AMD and Celtic are probably more professional as Abid is like me a small one/two man band setup, but his price reflects this. His map did exactly what i wanted and im certainly pleased with it and his service.

Your car has almost done 100k. Are you sure it will handle a remap? How are the inlet port motor? And the lower crankshaft bearing? Both very very weak areas on V 6 diesel

My V70 T5 Volvo was on 160,000 when re-mapped so i would of thought a Mercedes would of been on par engine wise especially these 3 litre straight 6 and V6 diesels which i read about before purchase!

The chap i bought the motor off his son was a very good mechanic who owned his own garage and he replaced some motor down the back of the engine which apparently takes 14hrs book time??.....so i think it must of been these items which were replaced......

Please tell me more ...what are these inlet port motors and what do they do?

Is the weak lower crankshaft bearing on this 2987cc engine as it holds the world record endurance run?

I am willing to learn as the motor is fast enough comparing acceleration on the move as in this Autocar Review?........just thought a bit more may not hurt !





After a lot of fine-tuning, the second-generation Mercedes C-class has matured into a deeply impressive car. But some of its engines are beginning to show their age, so Merc has developed this new four-valve-per-cylinder 3.0-litre V6 turbodiesel. Owing to its compact dimensions, it is the first six-cylinder diesel to find its way into the C-class, where it replaces the old 2.7-litre in-line five-cylinder unit.

The engine uses an aluminium block and cylinder head to keep weight down. Boost is provided by a variable-vane turbocharger that works in combination with the latest piezo injector technology for more efficient blending of fuel and air.

The result is 221bhp at 3800rpm, but it is the torque that really moulds the driving experience. Mated to the standard six-speed manual gearbox, the new engine dishes up 306lb ft of torque between 1400 and 3800rpm. From the off it is refined and flexible, the engine barely perceptible under 3000rpm.

But it is even more impressive when attached to the optional seven-speed automatic gearbox, when the torque increases by 70lb ft to 376lb ft between 1600 and 2800rpm. The effect is dramatic, thrusting the C320 CDI firmly into the performance-car ranks. This is an awesomely quick car. Mercedes claims 0-62mph in 8.1sec for the manual and 6.9sec for the automatic, the added torque combining with more closely staked gear ratios to offset the weight of the bigger gearbox.

To fully appreciate the new engine’s achievements, however, it’s best to look at the 50mph to 75mph in-gear time of 6.2sec – the same time as the 362bhp 5.4-litre V8 C55 AMG.

With thumping torque, strong economy (40.4mpg combined) and the C-class’s excellent handling and cosseting ride, this is a breakthrough engine wrapped up in a hugely impressive junior exec.

Just been reading about failure of the M55 shut off motors on these engines.

I checked with the seller and it was this item that was changed and it does fit in with the mileage they can fail at.

I shall checked tomorrow if there is anymore oil wetness or the later turbo gasket to intake pipe been fitted!.....as some say this damages the coil in the motor.....at least i know it has a new one fitted....

 

[crockers]

All I can say is I had my inlet port motor go 3 times. A rare occurrence but I do know of others who had theirs go twice. Crankshaft bearing cost £7.50 for the bearing but entailed the whole engine out. 14 hours no...it took a week at main dealers.

But your maybe a peach, mine turned into a lemon. Thank god I had warranty Direct

 

[KeithJG]

I just guess all the car manufacturers are at it ......making inferior parts for there motors to get more money out of us owners to keep the franchises running!

My last Volvo the bombproof V70 T5 classic shape motor.....i was scared to get rid of it as it was so reliable but in the end i swore i would never buy a newer Ford enhanced Volvo as they were breaking all over the place especially the S60 just to make more money for the loss making Volvo when Ford bought it...

So i decided if all the makers are in it together at least i can do it in more style by owning a Mercedes...Lol

All motors have there problems not least my other motor a diesel Zafira

So i shall just enjoy the C320 as long as i am able......

Personally i think with regular oil and filter changes your's will be fine keith, i always change my oil and filter at 3k regardless.

Yes, that does sound a good way to keep the engine in good order despite the service mileage of 9000 quoted....

The seller also told me he always replaced that turbo air intake seal at every service so i will do the same at the next oil change...

I think this motor may see me out @ 66 so i may just give it a big birthday Lol...it is already in better shape than myself !...

 

[crockers]

I changed my gearbox oil every 40-45k.

Just had a price from Celtic Tuning and this is what they said considering Dover is the opposite end of the map from Cornwall!

"The cost of the remap is £295 all inclusive for which we travel to your location whether it is home or work place. This comes with a 14 day money back guarantee which gives you plenty of time to ensure it is exactly what you are after."

Also what i can expect...224bhp std modified to 290bhp + 66

376lb/ft std. to 463lb/ft + 87

Sounds like an unrealistic gain for a standard stage 1 remap, I'm guessing that you don't get a running road with mobile services, so there's no way of proving the gain & what's even more worrying is that the file is being worked on without testing how the car is taking it... which makes me think that its not far of a tuning box perspective, just increasing the restriction figures & giving false readings to the ECU.

I'd go for a rolling road remap from a reputable, well known & respected tuning company OR go for a pre-written engine specific map (again from a reputable tuner), I presume that the R&D investment is heavy to develop a good pre-written map.

 

[easycheesy]

I would always go for a remap over a tuning box, tuning boxes can never truly control all aspects that a remap can.

Whilst i totally agree on what you have said, how come a Brabus Box works ok?

 

[luckyamg]

Remap for me.

A remap will be done specifically for your car (even the same models can vary) where's the tuning boxes are generic. A good mapper will get the most out of the car for both performance and economy and are worth their weight in gold.
