Does shifting later (6600-6800) result in quicker 1/4 times? Isn't MB's max HP rating at 6100? I guess the dyno would prove on paper if there is more power above 6100.

 

I doubt it will make you any quicker unless you can get your engine to breath better up top.

 

Max power will be made around 6100, but you can hold that power out to 6500. By increasing the RPM, (and maintaining peak horsepower a little longer) you "should" be able to get down the track faster. Especially if you can trap 130 before hitting 4th gear 10.XX

 

Thanks for the info! But is this the Eurocharged in daly city? I'm assuming you just drove there yourself?
I love the sound of your car... wish I had an E.

 

Legit? Wiz Khalifa is a ___________.

Also the shift into 2nd and 3rd will be at a higher rpm so morel power from that too. It's power under the curve that will get you down the track the fastest not just the peak.

Real question now is would ported heads and cams help more now since the higher rpms is where they would probably shine. Seems like that's how the SLR does it.

 

I did it at home and sent it out to Jerry in Texas. Vlad at ASP is a Eurocharged distributor and is a very good friend of mine.

 

Wiz Khalifa is a BALLER. lol That Mobb Deep song was pretty siick!

 

correct....we have a few customers that told us they improved their traps and et's...

 

So when will my TCU be done?? Oh wait, I still need to pull it out and ship it.. jeez!!!



Seems like everyone LOVES this mod. My magic 8 ***** says: Yes

 

Go for it bro! You won't be disappointed.

 

OK..... now I am officially confused / embarrassed.

All this talk about manual shifting got me curious, and on a long trip today I decided to do some experimenting with the paddle-shift buttons and transmission modes.

Here is the traditional view of the dash when "M" mode is selected.



You can clearly see the current gear on the left side (3rd) of the odometer reading and the transmission mode on the right (M) of the odometer. (OK, the photos are actually NOT that clear...but you can still tell what they say! )

However:

You can still shift manually even when you are NOT in manual mode, as indicated by the photos below:

Comfort Mode:



Sport Mode:





In both cases, the shift buttons/paddles will still allow you to upshift and downshift and if you pull and hold the downshift button for 2 seconds it will select the closest gear to match the speed you are travelling. If you press and hold the upshift button for 2 seconds it will put you back in "D" (Drive) mode and go back to a full-automatic shifting again.

My embarrassment comes from the fact that I assumed that anytime I pressed the shift buttons and saw a numeric value on left side of the dash, I was in "Manual Mode".... but clearly that is not the case.

The question is: What kind of shift behavior is the transmission going to exhibit when you are shifting manually in either "C" or "S" modes? Is a manually-shifted Comfort mode going to be a lazy manual upshift like you normally get in Comfort mode when it's in full automatic mode???

I fear that much of my previous complaining about the "M" mode shifts may actually have been the fact that I was manually shifting in Comfort mode and the transmission was taking it's sweet time and giving me soft and slow gear changes.... just like it would do by itself when in that mode.

Hopefully, I'm not the only one who has been confused by this.... but I'm going to spend some time driving around in "real" Manual mode to get a better feel for what it's supposed to be like.

try doing this in a 2003 and let me know if you have any success

 

on my 03 the shift buttons are inactive in C and S. they only work in M

 

My 05 I can hit the downshift button or hit the stick to downshift while in C or S mode.

 

You cant shift when you want to in c or s mode. M mode ftw!

 

Same in my 05..

 

In my 03 S55, I could shift with the buttons and the shifter in C and S. Awesome.

 

A baller? No, this is a moron. If you believe that then you need to have your mind purged and retaught everything from K1-K16. What do they teach you at school?

Your comments embody what is wrong with society today.

John Mack, Jamie Demon, Lloyd Blankfein are ballers.

I really liked enjoyed Gran Torino with Client Eastwood.

 

K1-K16? Where do you live? It's K-12 here in the U.S. of A.

Those gentlemen are bankers... not ballers. I imagine watching them ball wouldn't be pretty.

 

What can I say Wiz Khalifa is the best in the business right now. You dont't even know. And I'm probably smarter than you because its K-12 not K-16 as DTM stated earlier. Don't be hatin dawg.

 

..and here I thought having your own opinion was permitted. I guess everybody has to share the same taste in music as you do or they'll automatically "blacklisted" by you. The guy likes what he likes, why does it matter?

 

As far as I understand, S and C mode will allow you to use he buttons, however, the tcu still interrupts.

In M mode, you control the up-shifts. The tcu will downshift for you but you have the ability to do it manually as well. The only difference I've noticed between S and M is that M will not allow early up-shifts or hard down-shifts as well as allow you to manually go into 5th gear. Also, M mode always stays in M where S or C will go back to true auto once you shift past 4th.

After reading this thread I finally understand what all the super car rave is with the shift speeds. Lambos, Ferrari, and Porsche all have these crazy shift speeds, milliseconds, and now I finally understand why this is important!

 

Let me try to clear up the differences between M, C, and S mode. This is on a 2004.

In M mode the shifter/buttons will allow you to upshift and downshift as you please, as long as you don't depress the kickdown button. You can be in 5th at 45 mph and nail it(without activating the kickdown button) and it'll go to 100% throttle in 5th gear. However, if you do hit the kickdown button in M mode, the tranny will still downshift to the lowest possible gear, and it will upshift at redline without hitting the shifter/buttons.

In C and S mode, the shifter/buttons simply allow you to select the highest gear that the tranny will engage. Stop the car, put it in S or C, select 3, and accelerate normally. The tranny will upshift just like normal but will not go past 3rd. It's just like putting the shifter of a traditional automatic in 1, 2, 3, or 4 instead of D.

In C mode the transmission will start off in 2nd gear from a dead stop. If you nail it and activate the kickdown button it will shift down to 1st and probably jerk a lot like it's fumbling around. If you don't activate the kickdown button it will stay in 2nd. Sometimes(especially when cold) it will feel like it's upshifting from 1st to 2nd, but that's just the convertor locking. These cars love to lock the convertor as soon as possible, and it's pretty rare to get on it and have it unlocked. About the only time that happens is if I hit the brakes hard and then accelerate immediately. The convertor doesn't slip much, but it feels like you picked up 100 rwtq, like a stalled automatic.

Edit: If you want to have some fun and impress people, put it in C mode or M2 and got WOT from a dead stop without activating the kickdown. It'll do a REALLY nice pull from 0-80 mph, especially with a larger pulley.

 

How do you go WOT without activating the kickdown?
