Hello everyone,

Yesterday when I was going out of work I had a nice run against 2011 c63. He is running LT headers and drop filters, tuned by PP performance. Mine:2013 all stock accept a tune from eurocharged. We started from 80KM to


260 KM which is equal to 50 MPH to 160 MPH.

I was really surprised as I was expecting him to blow me away from third horn, it turned out that I was pulling on him lol "thanks eurocharged for the great tune".

This race was in an empty road not even single car was there at that time " this is for people who are going to turn this thread to an advising session" we all adults and we know when to race and when to not.

Enjoy the show

Lmaooooo

nice run

Yeah, man. The EC tune is awesome, especially in manual mode. It surprises me sometimes, too.

EC rulezzz .

Honestly thats almost a bit embarassing spending that $ to lose to a single tune. Well done EC! But doesn't make sense.

I have the V5 tune why does it seem like it pulls harder in S mode?

Nice.

But something is very wrong with the red c63. A very bad tune perhaps.

alamoudis2

honestly speaking I don't feel there is a difference between M and S+ accept the chance to shift late or early is there in the M
I use M for drifting S+ for racing

alamoudis2

totally agree, he is going for a retune soon and we will race again to see if it makes any difference

I guess you were on second gear. What are the chances that this guy was at third gear and possibly on C mode?
Just some random thoughts.

Thanks for posting the video. Not what I was expecting. How surprised was the other guy?

alamoudis2

surprised and disappointed. he asked for rematch three times right after the race and every time my car pull harder lol

I have V5 also. For me, I feel like it's pulling harder in M mode bc I can control when to shift. My transmission is sluggish bc I'm almost always sitting in traffic so it adapted that way.

I think in the USA there are two tuners who can get the most out of the M156 and they seem that be Eurocharged and OE Tuning.

Similarly in the U.K, we have Eurocharged and MSL. There are several companies who can tune the M156 but they never seem to be able to extract the true potential and if you're lucky, you will get you 500hp at crank but more often less and you eventually see these cars changing for EC or MSL.

For what it's worth, I ran my headers car with a custom EC tune against a stock car with EC tune and I didn't have trouble pulling on it. It's not like it was standing still or anything but when the car can actually breathe high up in the Revs, you really notice the extra performance.

Should go something like this...

First, OP has a P30 engine with tune, so maybe gets a little more power after the Eurocharged tune than a non-P30 C63 would, lessening the gap between his car and the header and tune equipped red car.

Secondly, per the owners manual, the progression of C to S to S+ to M settings provides progressively quicker shifts by the tranny. In M mode, the shifts are "at least" (paraphrasing MB's own word here) no worse than 1/2 the time of the C mode.

The difference from C mode to M mode is therefore up to 100 msec (i.e. 1/10 second) per shift. If you race from 50mph to 150mph, that's a handful of shifts, and therefore a handful of 10ths.

At 50 mph, you are covering 50/60 x 88 = 73 feet per second. At 150mph, you are covering 88 x 150/60 = 220 feet per second, or 22 feet per 10th second. So, in this race, each individual shift could cost the red car 7.3 to 22 feet in relative position! 7.3 feet is half a car length, and 22 is 1-1/2 car lengths for a C63.

How many shifts occurred? Probably 5.

The OP"s margin of victory falls easily within this scenario.

Food for thought.

This is what (a) taking high school physics and (b) reading the owners manual get you to thinking about.

p.s. The "Mexican" scenery is, as always in such videos, interesting.

jay rick

The prefacelift doesnt hv the S+ mode. It has the S mode though.
is interesting that one video was the facelift pulling and the other was the preface pulling.
My guess driver and what gear was pulling makes a difference.

This was not Mexico, it was in Saudi Arabia
