RWD CLS63 - worth tuning?
Hello everyone,
I have a 2014 CLS63AMG S Shooting Brake. In Australia, we get only the S version but in Rear Wheel Drive (the 4Matic is not made in right hand drive yet). I like to tune cars towards the end of the warranty period.
I'm wondering if it would be worthwhile tuning this car, given that it is not AWD. Would extra power and torque give meaningful increases in acceleration or just more wheelspin?
Cheers,
Steve

Those are just my thoughts. It's obviously not a cheap decision and you already have a sick car, so you can't lose either way!

Thanks OrientBlue3 for your reply.
I'm not going to drag it but I'm definitely a keen driver! My RS6 was tuned and would do 0-100km/h (0-62MPH) in 3.8sec repeatedly, so I'm used to a fair amount of performance. You're right, for rolling acceleration tuning should help a lot anyway.
I'm hoping a tune will also improve the accelerator pedal response? At the moment there seems to be a delay after you stab the pedal before you get an engine response, and then the response doesn't feel quite linear. It gives it a spongy disconnected feel which spoils an otherwise excellent car.
Where did you get your tune?
Have you ever measured the 0-62 time after tuning it?
Cheers,
Steve

It depends on your goal. Are you dragging it? If so, probably yes unless you are using wider (than stock) drag radials. I just had my 2012 RWD tuned and the throttle response is immensely better, the car sounds significantly better (more barks and gurgles than before tuning)
which tune??
and definitely a tune is good for rwd youll probably get higher trap speed than a AWD cls, and maybe even beat a tuned AWD cls in 1/4 with good drag tires...
from what ive seenbthe 4matic really robs power... rwd are quite a bit faster.

really tune changed the sound?

Now fast forward and we have nearly 100 extra whp (600 range) when tunning a 63 biturbo. I am not sure how that thing will have any traction in 1rst or 2nd.
I do not count the drag strip as your everyday event. Normal roads are what these cars are daily driven on.
So the question you should ask your self is how often do i do high speed roll on races? and where do i have to go to be able to do it, vs ever day usable traction and acceleration of a AWD
We all want the fastest, but we also want usable at the same time

Pumpkinate- I have the Eurocharged tune. They are great guys. Definitely give them a call if you are considering a tune. I have not had time to do any 0-60 runs yet as my car is at the dealer getting the rest of my mods installed. I did also go with the Weistec spark plugs which are a step colder than stock given the Texas heat, I thought it would be better to be safe than sorry as some cars have had misfires with tunes only.

Thanks,
I've decided I'm definitely going to tune this car. I tested it tonight with a "PerformanceBox" and the best I could get 0-100km/h (0-62MPH) was 4.4sec which is surprisingly slow. It seems to lose most of the time off the line (it seems to hesitate before picking up the revs). It could be that my car has some mechanical issue.

Now if it top speed and roll on races then yes go for it
it will be more violent down low with a tune, which is fun, but i wouldn't expect better 0-60 unless you are running some good rubber

i don't know how you think you 0-60 times will improve with more power...you will just trigger traction control

I tried a few more runs tonight and got my 0-100 down to 4.1 sec, not too bad for a wagon. There's a bit of a learning curve with this car. I found the fastest runs are in Sport, foot on the brake, rev to 2000rpm, then foot off the brake as you smoothly depress the accelerator more. Strangely, the Race Start function was way slower, doing around 5.1 sec!

No rain, but I had done quite a few blasts before trying the race start function, it might have upset something Also, the road surfaces in rural Australia are rather poor. One thing is clear though, at least on my car, the Race Start is slower than doing things yourself.
The car definitely struggles to get off the line, but its rolling acceleration is very good:
Those 30-50 and 50-70 times are exactly the same as my old RS6.
