So the '07-'09 W211 E63's have standard SpeedShift transmission programming. No throttle blips on downshifts.

And yet the '09 CLS63 *has* SpeedShift PLUS, with throttle blipping on downshifts, like the C63.

My question: because the CLS63 and E63 are essentially the same vehicle with the same engine, transmission and power train...THEORETICALLY could I purchase and install an '09 CLS63 ECU unit and install it in an '09 E63 without any reprogramming required to get the SpeedShift PLUS programming into the E? Taking a wild guess here, wouldn't the programming be the same for both vehicles, minus the trans programming?

Wouldn't the unit drop right in? Or do the ECUs have a proprietary/car-specific coding that would prevent this? Maybe I'm way off...or maybe this would work?

Someone edu-ma-cate me here.

Wow, over 500 views and not 1 reply yet?

Is this b/c no one knows whether it would work?

Anyone? Bueller? Bueller?

ECU's are VIN coded, but they VIN code them at the dealer (they're generic, but won't work until you assign them)...Though I have no idea, I always wondered why you couldn't get that TCU code in the E....

VCA_AMG

Right on. Sounds like there could be a way, then. Time to talk to the service adviser or manager.

I've read on the AMG private lounge that it's not possible even though the very similar CL63 and C63 have it because AMG would have to write new software for the E63 and re-certify it. AMG did not see it as being cost-effective. A couple SAs confirmed this too.

I posted a thread about this a year ago.

This is the point of installing a CLS63 programmed ECU w/Speedshift Plus already loaded into the E63. The engine, engine management, sensors, and transmission are the same between the CLS63 and E63 so far as I know. What would be the difference?

You don't understand, they're Vin - coded meaning ECU will ONLY will work on the car w/MATCHING VIN # Your MB dealer can't/wont do this PERIOD. They wont even sell you an ECU from another model w/OUT matching Vin #'s

Seems you may be confusing CL63 with CLS63... BIG difference there...

Let's just call McLaren F1 and see if they can retrofit some seamless shifting boxes

VCA_AMG

Ok if they're VIN coded then that solves the issue...can't do it. That's the part I was unsure of.

BTW not confusing the CL with the CLS at all. The '09 CLS 4-door has the Speedshift Plus rev-matching downshift/throttle blip programming. Considering the CLS and E-Class are essentially the same car w/the same engine & transmission, it seemed like it could be possible to swap out ECUs.

Too bad MBZ won't do this. Doesn't seem like any re-programming necessary.

LB63

AMG Private Lounge said that they have to re-certify the E class if they incorporate SpeedShift Plus since it affects emissions or something like that.

Knowing the new E63 would have the MCT they figured spending the money to change the programming on the last model year of the 211 AMG was not worth it.

I suppose you can be the guinea pig and get the computers from the CLS with the VIN and try it on your E

This is exactly why I also think a 09 CLS 3 Spoke Steering wheel will fit on the W211 E63 as well.

What is the real benefit of doing this? How does the '09 CLS63 perform vs the E63, is something really noticeable? Just curious...

LB63

I just sounds superb to hear the throttle blip on downshift I don't think it makes the car faster down the 1/4 mile. It may help on a road course but I'm not sure about that.

VCA_AMG

What he said

I also think a 3-spoke CLS wheel would fit, and interestingly enough that's another pet project of mine!

Just blip it manually with your right foot. You know, like with your heel in a MT tranny.

DAGREEKNYC

whats this blip ? and whats the difference with the speedshift tranny ?

juicee63

the vin coding screws everything up.

Im sure it is possible but you would need to be able to hack the code to get the car to start and not reject the foreign ECU

VCA_AMG

This is what I figured but wasn't sure when I originally posted. Thanks!!

Blip= Engine will match rev as it down shifts. Most SMG's (Like M3) do this as well. It is like making a really good heal/toe driver out of an average joe.. like me


So in laymans terms: Whan you hit the down shift button, or when it does it on its own, you will hear the engine rev about 500 RPM over where it was when the downshift was initiated. Thats about as good as I can explain.. keeps the car from actually slowing on downshift abrubtly
