SoCalC43

Hello MB World,

I'm a new member and just took delivery of a 2017 C43 Sedan. I've done a bunch of research on this site for reviews and tuning options so I'm glad to finally be a member and I'm looking forward to getting to know some of you guys!

Car and Driver just posted results from their instrument testing and I'm impressed! The car is much quicker than I expected, here's the link:

http://www.caranddriver.com/reviews/...an-test-review

0-60 in 4.1 and 1/4 mile in 12.7 @ 110

A lot of people say the C450 is the same as the C43 but that is definitely not true as I've never seen a stock C450 do better than 4.5 0-60 from any reliable source. The new 9 speed transmission and the other changes must make a huge difference. I knew the C43 would be quicker than the C450 but I was surprised that it beat it by so much. For reference, here is a link for the C450 test results:

Please let me know your thoughts...

Here is a bit better of a result for the c450. Gearing makes up for a few tenths, this is true.

If there is anything we can do just let us know!

If only it had a DSG with launch control.

SoCalC43

If only it had a DSG with launch control.

Launch control would be really nice. Do you notice in manual mode it seems like 1st gear fuel cutoff is way before redline? I just got my car a couple weeks ago so I'm still trying to find the best launching technique.

Hold brake, hold throttle. let go of brake. shift at ~6250 rmps.

done.

The quicker acceleration results are all due to the 9-speed. The trap speeds are more or less the same within margin of error 108-109 vs 109-110.

Really isn't that much difference between the cars besides the optional performance exhaust and the much better transmission.

​​​​​​The car definitely needs launch control though.

I chose AMR Performance for my C43 tune, because they have the highest proven gains with the 43 and the 450. One of their client's went a 12.2 with their stage 1 tune. Once I saw that, I called them up and bought the upgrade lol. If I had to recommend a tuner to any C43 owner or any car owner in general it would be AMR. Stage 1 alone is the most unreal difference from stock!

Not trying to discredit you nor AMR but a little FYI Eurocharge tune for our cars hit a 11.8 @ 116mph or 117mph lol. Placing my order for the tune tomorrow.

There does seem to be something fishy with AMR - but still putting down gains, regardless.

Did they post a time slip? I would love to see that. 11s is moving for this platform for sure. I would also be curious to see what their mods were. I guarantee it is more than stage 1 which was the only modification that AMR customer car had (also consider the fact that it was his first time at the track). Last I checked Eurocharged went 12.3 before putting nitrous on the car.

Thats a great time but that was after putting nitrous on the car. Not to mention absolutely no videos of this being done.


This comment definitely has me laughing

A company puts down gains, proves it with videos at the track as well as numerous customers putting down the same track times including one guy on instagram going 11.9 but something seems fishy?

AMG_FVR

This is correct! The difference is unreal.

The time one posted in another thread by Eurocharged.

ShazV6

Guys please view the link below. No nitrous used. Tune only! Best in the market if you ask me since they have time slips to show from customers.

Granted not all customers have the ability to go to the track with other companies tunes... but yea you get the idea.

Blacked out E63

None of those slips show an 11.8 as well as they show different dates, times, etc.... not to mention no video of these passes whatsoever. I would rather see a company post a video with a slip then just a random slip with no other proof

Also if you read on in that link you posted, I would agree with this guy who commented on that same post, as he is 100% right, see below comment:

believing crafted dyno charts is giving a tuning company way too much credit.

I'm not advocating for eurocharged either.

The only comparison I give a company validity for is hitting the 1/4 stock. Tuning - hitting it again the same day (if not similar conditioned day) and showing the numbers.

Dynos show how a specific car increased it's power. You cannot compare it to another dyno or other cars unless they used the exact same dyno.

Anyways, AMR should be putting down better numbers with their claimed figures, IMO. It's still an impressive gain - I just think their claimed improvements might be a bit idealized.

SoCalC43

Is anyone using 91 octane with their tune? I live in CA and can only get 91. I'm curious if it's worth it to do the ECU stage 1 tune with only 91 octane.

Gungaslow

So is AMR or eurocharged the way to go for a 17 c43????

AMG_FVR

For price, support and power delivery is Eurocharged!

Arthrodesis

Save your time and money. Go with eurocharged

Gungaslow

I was gonna go eurocharged until I realized AMR is better and is proven and tested longer..AMR is also faster.. in cool weather AMR tune is in 11s.. all the 12.2-12.3 runs have been in 90+ deg weather...

getmercd

Exactly! That was the same thought process I had before selecting my tune. I am sure Eurocharged has a quality product, but the AMR tune is just more in depth. I can't wait to see what they do this year with our platform and hopefully they get back to the track before it stays 90+ out lol

ShazV6

Bro his slip does show a 11.8 lol. Did you look at page 3 or 4 i believe it was? His car # and date and track falls all under the same day. You think that can happen if he goes on another day?? If so not so smart on your end bud. And the guy below is completely wrong. I took my c43 coupe to the track myself with 8 different slips. I had a time of 13.6 @ 104mph and my last run of a 12.9 @ 107 mph. So please don't tell me that cannot happen with that guys 11.8 run. His track temps weren't the best as well. I have all my slips. If you need them i can show. Please view the link below

And for the power ill stick with Eurocharge, once again nothing against AMR customers and their tune or OE. I guess personal preference. But if we are talking factual track numbers, Eurocharge has got it.

Gungaslow

Local guy here at track in newhamshire hit 11.88 on his c43 with just AMR tune and it was about 63 deg.. I saw it with my own eyes.. that's why I'm gonna go with AMR!!
