Eurocharged ECU Tune: HIGHLY RECOMMENDED

[C43inNC]

Just had this done on C43. It's a different car now. Absolutely amazing! Can't recommend these guys enough!

[Goldeni245]

are they in North Carolina?

[C43inNC]

They are in Houston, they do online tunes however which are fantastic because you don't have to remove your ECU. www.eurocharged.com

[Goldeni245]

online tunes? 0.o how does that work? do you plug something into your obdii port and they do tune it from a remote location? It doesn't seem like their website explains it very well. Is that what you did?

I'm looking at the spec differences for a c230k...201 hp and 227 lbs foot of torque looks like a a pretty amazing jump!

[C43inNC]

Yes it's what I did. Very easy, and very powerful stuff.

[zmatt]

Do they offer tweaked maps or just canned tunes? I'd like it to take advantage of my mods.

[C43inNC]

Tell em what mods you got and they will customize it to that. The owner Jerry is a freaking wizard I swear. Plus you get FREE retunes the life of the car if you add more mods.

[thegame]

It seems that the only w202 that they would work on is the C43, would they work on other w202s?

[C43inNC]

Send them an email, they will get back to you real quick. I'm pretty sure they will do other W202's

[C43inNC]

Shawn Dirtywhiteboy Long Jerry I got some W202 friends on a forum who want their cars done, do you do C230 Kompressors and C280s?

Hop on it boys!

[Pagz]

Tell em what mods you got and they will customize it to that.

Someone clear this up for me, how do you replace maps on a modified car when you have no real world feedback as it is being done?...or do you?

If you were say to take it for a drive at multiple loadings/RPM and varying ambient conditions and datalog the whole lot than maybe...but is that being done?.

If they are providing maps based soley on what mods you have told them they will be far from ideal.

[Sulaco]

As a rule of thumb, I've never believed the hype for ECU tunes. I would be very pleasantly surprised if I could be proven wrong, though.

[zmatt]

we should organize a group buy. Count me in.

@Sulaco
It all depends on the motor. An ecu tune will get you more power because most cars form the factory are mapped conservatively to balance power, economy and emissions. You can get more power at the expense of the other two. A modified car will obviously benefit more and as a general rule forced induction cars at least in my experience will benefit a lot more with a tune and no mods than NA. That's because boosted factory cars have very conservative ignition and fuel maps to ensure reliable operation. With the stock output the C230K doesn't really need 93 octane, tuned right it could probably get by on 91 just fine. Because we use 93 though you can crank the ignition timing way up and gain a good 20hp or so with no mods.

Now I'm already making close to 20 over stock as it is and I am not running even close to a good map, you've seen my afr. Correct that shit and you will get a nice bump in power.

[Pagz]

I am not running even close to a good map

This is what you will get with a one size fits all tune,how do you correct that? =)

I would imagine the biggest benefit would be a sharper throttle responce.

If you guys do go ahead please post before and afters.

[zmatt]

lol thats what I get for having a stock ecu and being lazy. If they can tailor the maps thats awesome. I have friends who have done similar things on other cars before and the results highly depend on your access to a dyno and the skill/patience of the tuner. If you can get some dyno time and send them the data then they can make a good tune.

right now I need to get my 202 patched up. still fighting state farm over that bitch who hit me.

[anf6789]

Now if they could tune my C36 Ecu for the addition of a turbo instead of running an aem piggyback that would be cool....
Obviously remotely while the cars on the dyno ect... Not sure if the stock Ecu has enough room to play with...

[zmatt]

I doubt its a room thing. The ecu has plenty of space for a map. The issue is probably 2 fold. 1 the HFM ecu likely uses a rom which has to be swapped out, you can't write to it like flash memory and 2 since most euro cars use Bosch ME I doubt if anyone has written software that can actually work with it.

[Sulaco]

What zmatt said is why you never see the same kind of ECU tuning on a MB like you do with other manufacturers. MB uses ROMs for their ECU's. A ROM cannot be modified. It must be replaced.

I live in West TN where all premium pumps deliver 93 octane. If I could get my hands on an MB diag/star tool, I'd absolutely change the fuel trim setting to RON93 or RON95 (or whatever tells it I'm using 93 octane gas). Otherwise, I don't see an ECU tune really doing anything.

[gakz]

Sulaco you sound like all the other nay-sayers, just stop it. An ECU tune on any car is going to help, even most 100% stock cars. Plug and play 2.0T engine I have in my daily was tuned (not on a dyno) and it is a 30-40whp gain.

Eurocharged has experience in this arena and has proven to get horsepower out of benzes with tunes.

How do you know it was 30 to 40 whp increase?

[gakz]

You know what a dyno is? There are dyno tune setups for a reason. You ever race? I dont mean just stop light racing. I can see its better to just ignore you

[Sulaco]

If you'd read the thread and noticed my first post where I said I'd be very happy to be proven wrong, perhaps you wouldn't default to internet fight mode.

Relax mate. I'm just being very, very inquisitive. I'm not the type to drop $500 on a "software upgrade" that's supposed to get me such a big increase in hp/tq. Am I a "racer"? No. And you're not a Mercedes Benz specialist. I'm simply stating things that are verifiable facts about older MB cars that I have proven from my own personal experience.

If I was so quick to go out and blow a weeks pay over a sternly worded testimonial on a forum from a total stranger online, I would have already done it.

As I said, I would LOVE to drop $500 on another 20 hp with zero labor. All im after is some verifiable data that it's not one of the many, many cases of automotive snake oil online these days. If anyone can post before and after dyno results I would happily pour over them.

And if you're claiming such a jaw dropping increase from an ecu tune, post the dyno results to prove it. But if it's not a pre-2002 MB, its a moot point anyway.

[gakz]

May want to talk to Eurocharged then. Ive been working with them for quite a bit for my SLK... with the pre-2000 M111 engine. With the M111, i would consider myself well educated. Just continue being a nay-sayer.. I can tell why all the benz modders don't hardly post on forums

[Sulaco]

Wow. That would also suggest this could be of benefit on my m104 1994 e320. Since you work for/with them, do you recall having ever done any m104's?

[gakz]

*facepalm

I almost couldn't muster the energy to respond to you... since you can't read,
Ive been working with them for quite a bit for my SLK

I see why this site died for a while

[Sulaco]

I honestly don't know how to respond either. You meet one member who is suspicious about ecu tune and have it all figured out.

I guess I should apologize for killing the site.

I'm really not interested in fighting with you. I really want to be proven wrong about ecu tuning on mb, but am yet to see anything definitive. I did find one YouTube video of s guy who had an ecu tune in his c43/55 who did a before and after dyno run and lost hp.

[nd4spd13]

Don't know about "older" MBs necessarily, but on "another forum" there are people attesting to the wonders of ECU tuning everwhere you look. Editing cars timing maps isn't a new snake-oil remedy, it's been done for a long time. Personally, there are some tuners that will stick god-knows-what into the ECU of your car and claim 50+ horsepower. Then there are others such as Eurocharged, OE, Kleemann etc. that claim realistic figures, aren't budget solutions, and very often have dynos to back it all up.

As far as the cookie-cutter re-flashes go, it's true that they will never be as good as a tune that is performed while the car is on a dyno. But for free, they are pretty good, and imho the guys at EC know enough about what they're doing to figure out how the mods affect our engines pretty well. Especially for the C43, where our base engine is shared by many, many models.

And to the OP/goldini, there are two EC dealers in NC. One is Euro Classics LTD in Durham, and there's one I think out towards Greenville. There may be one in Charlotte too, I'm not sure. Euro Classics charges $90 labour on top of the price of the tune, the other one does not. I have worked with euroclassics a bit before and didn't much enjoy my time with them... I was planning to make the trip to greenville to get the tune.

[Sulaco]

I wonder what risks, if any, there are to ecu tuning an engine with high mileage? Would this even be a factor?

[C43inNC]

All I know is, you can feel a difference in my car. The gear shifts are better, the rev limiter is higher, and it's quicker. It makes the car run BETTER for sure. I'm spinning tires with ESP on, which I wasn't doing previous.

That's awesome, man. I'd really like to compare our cars. Your's also has more than 150k less miles than mine, so it would be faster than mine either way!

But I've always wanted to talk directly with another C43 owner to compare notes, especially the launch thing. When you say "spinning tires with the ESP on" what exactly do you mean? Do you mean from a dead stop and FLOORING IT makes it try to spin? Or are you doing a brake-primed launch (where you hold the brake pedal, push in about 1/5 throttle on the gas, and floor the gas and release the brake at the same time)?

[C43inNC]

Dead stop flooring it, haven't really tried throttling it with break on.

[anf6789]

launch the bitch ;)

[Sulaco]

Hell yeah, man.

Typically ends up being a launch just like the one of this w210 E55: http://www.youtube.com/watch?v=RUQSp2qAIL4

Something sexy about that...

Just because this was just posted, thought I'd put it up here for people to check out. Obviously, this is an f/I car, which is going to be different from our NAs, but it still shows just what can be changed inside the ecu.

Just curious but what tires are you running? Also I may have asked you this at some point in the past, but where in nc are you?

[C43inNC]

Yeah you can add the guys on FB and they will tell you. They are constantly doing things on the E63.

Yep that's where I saw it.

[Pagz]

Aiming back towards the start of the thread,Its not apples with apples. I hope your not comparing NA tuning with forced?.

The reality is,any tuner with the required knowledge and equipment can up Hp by removing some of the saftey net incorperated in a stock tune,its nothing special,its piss easy if you can simply vary the PWM on the solinoids feeding the turbo's and add more fuel like on your E63. I dont think there is anyone here that wouldnt agree with this.

What people want to know is if they spend money on an ECU flash for the C43 what is the actual result?

If the result is "it felt better" people are going to question it.

If you provide drag times,dyno's or some other reference people are more likey to agree with you. its really that simple.

Excuse me,im having a rough day.

I was comparing NA with forced, but mentioned in my previous post that they're way different and I acknowledge that. As you said, either way it's essentially the same thing, minus the boost solenoid editing. Timing, rev limiter, top speed limiter, tuning for different fuels and different mods, all the same on our engines as the 63 engines, 55 engines, or any others.
It is true that Eurocharged at least has no actual dyno sheets or drag slips showing the gains they claim on the C43. There was a member on another forum that was going to do a pre and post dyno run with a ec tune + other mods, but it hasn't happened yet. I have been seriously thinking about getting this tune, and I will try and work out a pre and post dyno if I do. From what the op is saying though, it sounds at least somewhat successful.

Also mentioning something in an earlier thread, I also read somewhere that someone who replaced their 4.3l with the 5.4l indeed made more power with the stock, C43 ECU than they did once they switched it with mapping made for the 5.4l.

[RemoLexi]

I have to back up Pagz here, unless they held my ME and retuned it this is simply a G-force hoax I may as well tap a resistor to my IAT sensor.

Hence a REAL tune is on a dyno with your car actually being tuned otherwise why would I trust some hack with my ME that AMG tuned. You can claim to know all you want but you obviously take me for a fool if you want to trick me out of $500 for a blotchy 'tune'.

This thread is almost as good as the guy wanting to import and install a Chinese/Korean replica M104

[anf6789]

a forced induction tune is always going to produce results. up the boost up the fuel...power... much harder on an NA car. you can change the timing for higher octane fuel, but theres only so far you can get before it being unsafe. youll grab a couple HP of course, but nothing worth $500 on an NA car at least. Sure 335i's and GTI's gain really good results with tunes, because they are turboed. But if C43NC thinks it made a difference, thats all that matters its his car his money, he likes it there you go. A dyno sheet would be the best though

[RemoLexi]

Another question, does that's ME flash erase the encryption now required to be inspected during smog in CA per BAR smog regulations as of Jan 13' ?

Not all ME' encrypitions on German cars can be recoded back in place, forcing replacing the ME.

[anf6789]

Remo, could Eurocharged technically get into the 97 C36? my friends just got a dyno and will be working with eurocharged. just a thought instead of running a piggyback

[C43inNC]

You can see dyno sheets and whatnot for all the other cars Eurocharged has tuned. Why the hell would it be any different? And yes the car is remarkably different, if you don't want to believe it, that's cool. All I know is anyone who has ridden in my car pre/post tune sees the difference. Oh and by the way, one of my good friends owns a dyno shop and I'll be paying him a visit soon.

I don't get it... you're downplaying a company's tuning ability to dyno tune a customer's otherwise stock car, save the tune, and distribute it to other customers? Kleeman, MKB, Renntech are some of the biggest MB tuning companies, and you're saying that their tunes are a hoax? If Jerry at EC, Jeremy at OE and others are all hacks, then I don't know who is pushing all the limits of the 55k and 63 powerplants at the moment... and yes, a tune is one of the first things they do.
Maybe $500 is too much to pay for an extra 25hp on a 15 year old car, that I can see, but they offer sales quite often, and there is no abundance of power-adders for our car anyway, especially with such high (relatively) gains for that price.

Well said, hence why I would only buy during a sale, and why I'd get a reflash if I get a 5.4l to bump the numbers even more.

I believe you entirely, we are all just interested in how much of a difference there is.
Euro charged lists a tune for the 209 CLK55, the gains are 15hp and 22lb-ft. at a guess I would assume the 43's are a bit less?.
http://www.eurocharged.com/products/mercedes-tuning/clk-class/clk55/clk55-performance-engine-software-detail
It would be interesting to see where these gains are throughout the rpm range,can anyone see a dyno graph on it?(the page is not displaying properly for me)
Do they specify you run higher octane fuel after the tune? if so which grade?.

Edit: didn't see the specs for the 43 there, which they claim as 23hp and 24lb-ft.

Geez im tired and need to go to bed ,work days are long atm.

[C43inNC]

Gentlemen, I present to you exhibit A of my proof. Stock C43 0-60 is 5.8ish. Crappy launch, second try, I managed a 5.4 with no other mods but my Eurocharged Tune. Enjoy!

Any dynos to date?

[Sulaco]

All this talk of performance and pulls, and now videos makes me want to post a new thread where people post their w202 speedo as they do a launch.

Here's mine: http://www.youtube.com/watch?v=Ff0b8exjHaY

First pull, as you can see, couldn't get traction so I let out. 2nd pull starts at around :29 and according to YouTube annotations, it's 5.64--but I don't know how accurate that can be. I really wish there were a more accurate, reliable way to measure these things without a drag strip.

New thread incoming!

I hadn't paid attention to this thread in a while but noticed something peculiar being mentioned: how does a tuning company advertise gains from an ECU tune if they performed no tests to verify or back up their claims?

[anf6789]

im sure eurocharged used the dyno to develop the tune...

[Sulaco]

im sure eurocharged used the dyno to develop the tune...
yeah, that's what I'm saying. you'd think that they'd just post the dyno sheet and prevent the typical internet snake-oil claims. I admit I'm still skeptical, but I'm happy to hear that C43inNC is happy with the results. I'm a devoted w202 lover and I PRAY someone can post verifiable numbers that I can drop $500 and get another 25 hp without turning a single screw.

But my ultimate goal is to do a 5.4l swap and add a Kleemann SC + exhaust...

That's 450+ at the crank, I believe. If I can get my hands on a proper intake and kleemann cams, perhaps 470+

And I read an interesting post from a Kleemann representative himself about the M113 supercharger kit. He said that, for some reason, adding that same supercharger kit to a standard 4.3 engine (like in a CLK430, E430, S430, etc) gets you more total HP than if you add it to the AMG version in the C43.

That means you could yank your AMG 4.3 and store it. Buy one of many thousands of standard 4.3l MB engines lying in junk yards and slap on the kleemann SC and have 400hp. It's a direct drop-in.

[C43inNC]

...I shaved off .4 seconds on my 0-60 dude on my 2nd try and I've never done something like this before. I'm telling you, do it, and you won't regret it.

[C43inNC]

You guys want me to ask if they got a dyno sheet?

[thegame]

Sulaco I get in the high 5 sec or 6 according to your video. what you can do is take the video and using window movie maker, check it frame by frame. it will be alot more accurate then the youtube video.

If true I think I know why. The AMG 4.3 has a more aggressive cam with higher lift and more overlap. Not by a large margin but it's there. The regular 4.3 has less over lap and in forced induction cases that is preferred. It could very well be that the normal cam is better suited to supercharging. Of course S/C cams are even better.
