C63 ECU Re Map

[mika]

Benjy how are you
Well i guess i know following that remap!
How is it with kick down - beyond insane or does it not affect this much
Sounds good value especially if the feel is better

Hi Mate,

I'm good fella, really looking forward to seeing you and the boys on the 29th.

Yeah really surprised the difference this makes by having this increase even though its only 23 bhp up on the PPP set, its over 50 bhp on the standard car. But I think the torque through to 4000 rpm is the biggest jump I noticed straight away, just insane, to the point of being scary. The nice thing is the smoothness through higher gears and right the way through the rev range. To get that from a naturally aspirated engine is very clever stuff.

I think the value for money on this stage 1 re tune is definately worth every penny. As I said mate for almost the same set up and performance on a DR520, that costs you £10k on the standard car and only 20 of those babies were made, for the same you can have this for £650

I agree. The only way it can be done is if Mercedes are deliberately restricting the original output, possibly by not allowing the throttle to open fully.
surely no car manufacturer would do that because we all know that have their consumers best interest at heart, not manipulating things for profit.

A petrol engine requires a set mixture strength, and atmo only has a set maximum volume of air, put the two together and you have a pretty set maximum power output.
To somehow extract 10% more is a lot.

The on road performance figures will be interesting, as would a before and after MAF output reading.

Hi Dieselman,

Totally agree with what you are saying and tbh I wasn't expecting such a high result myself but these guys have done it.....

Yes my mate Nige has a proper tool to get very accurate figures which we will use for the new results I'll post this weekend. FYI todays before the remap on standard PPP the car got 0 -60 in 4.4 secs and 100 kmh - 200 kmh Nige could get to 9.7 secs. Once we have the new figures this weekend I'll post them.

 

[Nudenut]

Enjoyed today H, so pleased we got somewhere close to the DR520 and your target gains and pleased the car Dyno'd accurate stock power (B7 RS4 owners would kill for that!). The car definitely now car pulls harder, more noticeable from the off, a product of the torque increase which is great!

The increase in exhaust note is superb, car detuned to meet emissions/noise maybe? You say no physical change to DR520.... MMMmmmmm!

Enjoy and keep it and you in one piece!!

 

[Dieselman]

car detuned to meet emissions/noise maybe?

I can't see that. To feed the Cat the engine needs to run close to stoichiometric, so how can that be altered.

An interesting result, I await the timing results.

 

[Benjy]

Thanks Nige and again thanks for coming with me today and introducing me to the boys at MRC.

Yes the increase in the noise from the car is a little intoxicating....LOL. I wouldn't have thought that the re map would have increased the exhaust note, but blimey that did sound damn good on the dyno on the last run. The amount of pops and bangs!

Nail and head some what... pretty sure Mihnea's first port of call was ECU's allowable throttle after a call to Germany. Bit more tweaking here and there, timing and mixture I assume and she's flowing more air I understand (didn't get the figures I'm afraid).

Profit, surely not, C/DR / E but I'm not up to speed on any physical differences just know MRC are confident the map is safe.

I very much doubt the mixture will be altered and suspect the timing is controlled by the knock sensor.

I was thinking about this after our discussions the other day and the exhaust note pretty well confirms it. I suspect MB are restricting the throttle to reduce power on lesser models.

If I had thought about this, it would have been interesting to obtain a MAF output reading before and after and even a visual of how open the throttle was.

I still can't believe a car manufacturer would operate like that and charge the customer more for opening the throttle fully instead of restricting it...can you..??

Nope

Benjy - glad you're happy with it

That power figure is almost identical (just 1bhp in it), to what I got from the Brabus remap. Amazingly close actually...here's my pre and post Brabus graph again:

I was obviously blessed with a very strong standard car but the closeness of the results does prove that all these different remaps (regardless of who does them) all do the same basic thing...open up the throttle a bit (on standard C63's) and mess about with timing / mixture. I'm glad I got my refund on the Brabus if you got the same result (as that cost me significantly more than £650!!). I probably would have swallowed £650, even for the nominal difference but not the £4k+ they charged!

Also, your standard nm was also almost identical to mine (and a good 5% short of MB's claims too). The end result in nm is good though...a much better result than the power increase and as you can see, a huge improvement on the Brabus tune!

Dieselman - yes, 10% would be incredible for an N/A car but it is do-able on a standard C63 as they deliberately hold the throttle back (purely for marketing purposes...the C63 CANNOT be as powerful or fast as the bigger, more expensive AMG's ). It's just not do-able on a PPP one but the 5% increase Benjy seems perfectly achievable for a lot of N/A car's from what other people have experienced (just not in my experience ).

Damn you...damn YOU Benjy...this has got me thinking about a remap for the Maserati - do I reckon it can achieve the 40bhp (8%) increase that is promised?? No, no...of course not Note to self....stop being silly!

Heyyyyy.... how you doing buddy, so these figures I have are almost identical to your first C63 Andy? My god is that what Brabus charged you...no wonder you weren't happy. Yes I am happy with the results and notice a big difference in the way the car now pulls from a standing start, lovely noise as well (not saying it was bad before).

As for the Masser....come on mate you no it makes sense and if it gets you near that 40 bhp you are after you no this will put a smile on your face.

Glad you have had the MRC experience, I thought you would be pleased.

 

[Alps]

ignore me, just read the rest of the thread! lol

 

[Benjy]

Glad you have had the MRC experience, I thought you would be pleased.

Yes they are a good bunch of guys up there and very knowledgable about their sport They are all off to the ring in a couple of weeks in which I dont think there is going to be one car under 400 bhp there. LOL should be interesting.

I said that you were bigging them up on here and Mihnea said to say hi. What Audi is you have Graham, is it an S4?

Yes S4, getting on now but the 2.7 v6 bi-turbo is a gem. Originally mapped by Mihnea, on the road too long before they had the dyno. I think all the staff at MRC have had a go at fettling one part or another of my car

I haven't been active (apart from behind the scenes) on this forum in a long time, but when I saw your post I had to reply. I was pleased to see an MB/AMG owner using them and had to pass on my faith in them. Especially given a slight inbalance of views otherwise. I've known that Mihnea maps many vehicles not just VAG and if I had ever strayed back to BMW or Mercedes etc I would have been contacting MRC for tuning. However I also observed that MRC don't seem to (or perhaps haven't until fairly recently) promote themselves outside VAG circles in the UK. I don't know why, so I have never mentioned them on forums outside of VAG circles either before now. I do note they have non-VAG cars listed on their website now though. That said they never really advertised on the VAG scene either, as word of mouth and recommendation seemed to see them do well enough.

Sounds a wonderful car mate in which tbh before getting the C63 I was after an RS6 at mine and Nige's local dealer but being that it was one of the LE editions they wouldn't drop on the price and I wasn't going to pay £80k for one. So I have total respect for all things Audi and especially after Nige lent me his for the weekend when I was out of a car until my baby arrived.

I am pleased with the results on mine and being how fussy I am with my car on the cleanleness front and anyone who knows me knows this, these guys would have to be a bit special for anyone to be allowed to tinker and touch my baby. I agree with you its always good to be told from others that have used companies or specialists in the past to be able to make your mind up on these decisions and being that Nige and the results on his monster prove, these guys are a good choice.

that car looks sooo nice in black !
