What's up fellas. So I figure I get some real world results of how my stock 43 coupe would do on the track. I went to Atco raceway, the temperature was about 75 degrees. I was able to get a total of 7 runs in. My method of driving was traction off, sports plus in M mode, brake and gas till about 2k and then releasing the brake and flooring the car. From the picture the second run (13.6 @ 104.17 mph) my method of driving was traction off, sports plus only and let the car do the shifting and flooring it once the line turned green. It was actually my worse time doing so. My best time was a 12.9 @ 107.19 (last run ), mind you I didn't get clean shifts on this run for first and second gear (hit the limiter slightly). I know with a bit more time in the seat I would hit a 12.7 or even a 12.6. Fully confident I would. Now I can go back to the track with the tune and downpipes once I place my orders to gather more data.
Not sure if you could get it down to 12.6 as a 1.8/1.9 60' seems about the best this car will do stock. So unless you were screwing up your shift points somehow, you definitely can't get better launch.
Thanks sean, but that's the thing. I did mess up on my shifts slightly on first and second gear on that 12.9 run . Fully confident I could attain a 12.7 (high hopes 12.6). First time taking her down the track so I'm not completely upset. And after seeing track times from eurocharge I think I will be going with them paired along with weistec downpipes.
Nice, thanks for sharing the information, I look forward to your future posts. Any plans to do some runs in full auto mode for comparison? Any dyno plans?
Hey Gidrow, I did do a auto mode with just flooring it in sports plus with traction off. Got a 13.6, maybe if i did the brake and gas theory I would have gotten a better time but now I'll never know. Do i plan on doing a dyno, no. Next time at the track it will either be Eurocharge tune with down pipes or just the tune. I know i can get a better time stock than the 12.9. If I only did not mess up on my first and second shifts.

I can't wait to see the results Shazv6. When are you planning to order the EC tune? I was going to order this week but, my dog needed emergency surgery and the bill was pretty hefty If your before and after track results are pretty good, I will order ASAP.
I hope the tune will still be on sale by the time I am ready to order in a few weeks.

I was playing around today with racelogic vbox, was checking which start method is the best. Came to the conclusion that 2 pedal start with gearbox at full auto is by far the best and most consistent launch possible at this vehicle. Gearbox mode s or s+ doesn't really matter when you floor it, even in comfort if you manually put it at 1st gear and then do 2 pedal launch you will get exact same 0-100kph as s/s+.

Hey DameMD i actually was going to order it today lol. But now my car decided to have its driver side air bag light show up :/. So she is going into the dealer Monday and i will place my order next Friday. As far as when i will go back to the quarter mile i am not sure.

I was just looking at your time slips and I am really confused.I have about 40 years experience drag racing and have never got such inconsistent results.Your speed varies about 4 mph and et about .8 sec.Speed depends on horsepower and the mph should be very close on all runs(+ or - 1mph).The C43 is all wheel drive and should not vary more than + or - .1 sec. in et.
I have a c450 and the few tests I ran were very consistent.I was in Sport+ with TC off, automatic shifting.My 60' times were 1.9 sec,1/8 times were 8.19,8.20.Speed at 1/8 was 87,86 mph.I can run these times all day long unless something breaks.This was done with a GT2 timer.I used the timer at Maple Grove dragstrip on my previous car and the largest error between my timer and the strips timer was .09 sec.

Hmm, did you try any runs without doing M mode? I think I've seen a bit faster stock runs (like you said the 1-2 shift you had slight issues with) but regardless, nice times!
We have downpipes too, get the whole package from us! Give us a shout if you have questions.
Oldman&thec- Keep in mind, i had issue shifting as i did keep the car in M mode. Only one run i did in Sports + traction off and floored the gas pedal with a 13.6 but i had a horrible 60'. Keep in mind i DID NOT do the brake and gas rev to 2k and then floor it. Maybe my times would have been better? Will i know for sure? Nope. Fastest i seen stock was a 12.7. Maybe there is quicker out there but i am fully confident with more seat time id hit a 12.7 or better.

I did but with a horrible 60' as you can see from my post above. And wait, you all have down pipes??? I thought it was only Weistec!! Please send me the link i already spoke to Jake about the tune. I will always be a customer of Eurocharge. Had you guys tune on my 2013 c-350 and loved it.

I didn't mean to cast doubt on your times but I still think they are unusual.I can tell you from experience that the best starting method for my C450 is: Sports+,rev to 2000 with the brake on,traction control off,release the brake and floor it.Do not try manually shifting,you can't do better than automatic in Sport+.
Looking at your 60' time on the 13.6 run you must have had a huge hesitation at the start.Unless they changed something in the traction control of the C43 this should't happen with TC off.
God, 2,000rpm's is just not enough to fully sidestep the lag. If we could BB to 2,500rpm I bet this car could cut 1.6 60' times.
I'm just guessing here as I'm not a auto tranny expert whatsoever, but I bet that would be much much harder on the TC with just an extra 500rpms. I'm guessing that the wear goes up exponentially on the TC when slipping it?
Can anyone tell me how bad it is to do it at our 2,000rpm limit? And how often is too often? I've only done it maybe 5-6 times myself as I don't see a need on the street. Especially not knowing the full extent of how damaging it is, myself.

I don't think you can brake to 2500 rpm.The stall speed looks like it is 2000 rpm.I BT to 2000 and start within 1 sec.This minimizes the heat build up in the trans.I don't get much hesitation with this method.I think 1.8 to 1.9 is about as good a 60' you can get with no mods.

Short edit, took some more runs, turns out s+ is actually giving advantage. At s it runs factory 4.6s-4.7s to 100kph, at s+ it goes 4.5-4.6s. Thats for 200m above sea, 2 pedal start, +10C temperature and ps4 tires

Either you just didn't read my entire post or you didn't pay attention to it. Either way.....
Thanks a lot for sharing and great results that is really interesting. I have the C43 AMG Sedan and went to the 1/4 and 1/8 mile a couple of times. The best I did on the 1/8 mile was an 8.2 and 1/4 mile was 13.0 flat. I always had my RPMs around 2k 2.5k at the launch.
Here are some of the videos if you guys might be interested

Sorry about that sean.At 77 years old maybe my reading comprehension is failing a bit.I thought you were saying it was possible to BT to 2500 rpm.I overlooked the word "if" we could BT to 2500 rpm.

Bro that's the thing. I tried to do 2500 rpm and the car couldn't stay still, kept on nudging to move forward. I had to lower it to 2000 rpms. I know if i kept going with a BB of 2000 i was going to hurt the transmission more. Would i recommend doing it sooo much, def not. Once in a while i don't think it will break it. But then again i am no expert.

Good stuff bro!! Its definitely tricky taking these cars down the track with all these features to help with traction and how fast these transmission shifts. One slip and your done lol

Yup, once you pass 2,000 the torque converter starts to grab hold and the battle of the engine vs brakes begins lol.
Sounds like we're in the same boat. We both know [obviously] that the more you slip the TC, the more wear you're doing. But have no idea past that. I was hoping an expert on the subject would chime in here. I'd really love to get info on our specific application but what can ya do... I guess it's off to the U of Google I go
Plan on ordering my eurocharge tune Friday or maybe even this Wednesday. Dont think ill do the downpipes as of yet :/. I will be going to the track again in the next month or two if all goes right . Ill def keep my thread opened for updates.

If your before and after track results are pretty good, I will order ASAP.
