I think the question was not understood correctly.
With the SRT wing installed, the old flippy spoiler is GONE !
The wing mounts to the same place as the old flippy.

Yes, this ^.

The SRT mounting plate replaces the NA style wing and all that.

Update on my build:

Thought it was weird that I had a small puddle of coolant under the car whenever I go to drive it and see nothing in the bay. Figured it was the tank and that it needed more JB. Come to find out my lower radiator hose wasn't all that tight. Rather than mess around with a flathead (which was tight) I used a socket on my screwdriver ratchet thing and guess what!? No more coolant under the car.

Drove the car and immediately popped the hood to see if the tank was good and found one small pin-hole left. Let it cool, wipped it, JB'd and I'll check tonight but I'm pretty sure it's good at this point.

Not all that funny, I laughed but kind of pissed me off - I was playing in DAS to see if something wasn't set right for my "oil HI" always kicking on but no idiot light... Come to find out my ignition mapping was set at 87 RON!!!! That's like 83 Octane!!! I changed it to 91 with correction, and sure as $h** the car was smoother, gas mileage increased, decel was faster and smoother, slight kick in the pants difference, and traction light actually flickered in 3rd at 70... -facepalm

Also irritating the crap out of me ---- I trimmed the front clip of the V8 airbox around the upper radiator hose so that it actually sits in place correctly.. After driving everytime I pop the hood, it shifts and doesn't sit right. I have to force it all over to the left, then clip it in. Now for a while I've noticed a small white smear on the airbox drivers side. The torque is actually making the airbox impact the hood!

So now I have to tie down the motor mounts.

Gotta love builds like this though. This easy stuff is fun, gives me something to do when I'm bored. Plus everyday I'm learning what else I need to do to customer cars when someone finally decide's to have me build them one.

Steve, thanks again for the fan. I haven't put it in yet due to figuring out how I'm going to wire it, but it looks big enough. I kicked up the voltage of my pusher and set it to kick on earlier as well, I'll show you how in DAS when we get there on yours.

Josh ....That is so cool!!! Man, I can't wait to dig in to DAS & do some magic.

It all makes sense now...Thanks

It's crazy! I have almost a year of playing around in it and still find stuff every now and then.

Eventually one of my goals is to replace all of the chrysler encrypted modules with Mercedes unit's to try and access them in DAS. Replace SKREEM with DAS, swap the body control module, ABS/ESP module, etc...

Ours have Mercedes part numbers but there is something going on that's different. I'll find it and make it all Mercedes.

I think from this time forward I will refer to you as “SIR DASH” (and master leak fixer on the side)

Lmao! I try

Have you looked into the 55K TCU yet? I have a theory for your SRT TCU being remapped for the torque limiter but I need to dissect both. I'll probably try to buy one of each.

I have not.... I know you had mentioned that earlier but got shoved to the back file.... I guess visions of starting/running took front and center. Dang, I'm still stuck on the 722.6 NAG is all the same but I do believe you and will dig around over @ MBworld...

Also:
Do you think a Eurocharged TCU tune would correct any differences? ~Just thinkin out loud~

Yeah the 722.6 is the model number if you will. The last 2 digits of the 6 are the serial I guess is the way you could look at it.

722.618 - NA 320's
722.641 - 32 amg's
722.643 - 55K's
722.649 - 600s, 65/65BS and the Maybach 57S/62S

Probably. I'm pretty sure raising the torque limiter is something they do.

There is also a torque limiter in the ME as well....actually there are multiple torque limiter maps in the ME.

True, but since we're running with a 55K ME, that's not an issue.

I was worried that his car will do what Bob's (lantana's) did. Limit the torque on the way out of the trans. The ME bob used was for the engine so the limit's were ok there, but the TCU was restricting quite a lot IIRC. I think Bob said 290 ft-lbs which would have been input to the trans, so crank ft-lbs.

Thanks for the heads up though. Out of curiousity do you know the limit's set in the ME for the SRT, or NA's are?

I can check when I get home. I have changed mine a few times, up and back down. 900Nm seems to be the sweet spot for my car/tune currently. Anything higher and the EGS goes in limp mode. I suggest making all the maps the same as well when adjusting (3 in the ME for torque), it makes for less confusion between the ME and EGS when switching between different throttle maps.

How is that you changed them?

That's interesting that the trans goes limp mode with the torque limiter set "too" high. Maybe they just assume you can't get more than 663 ft-lbs out of the motor? lol

Popped my bubble...
So the specs listed here must be for the 722.645 55K and not 722.641 32K....DANG!

Copy and Paste>>>


click this link> 5-speed automatic transmission
E55 AMG (2003–2006)
The E55 AMG is powered by the M113 ML55 engine, a 5.4 L http://en.wikipedia.org/wiki/V8_engine with a http://en.wikipedia.org/wiki/Twin-screw_type_supercharger type http://en.wikipedia.org/wiki/Supercharger manufactured by IHI. The E55's engine was tuned to 476 PS (350 kW; 469 hp) and 700 N·m (520 lb·ft), the low end of the http://en.wikipedia.org/wiki/Mercedes_AMG#55 due to its longer exhaust system, compared to the Shorter Exhaust system http://en.wikipedia.org/wiki/Mercedes-Benz_SL-Class's engine at the high end which made 517 PS (380 kW; 510 hp) and 720 N·m (530 lb·ft).http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-9http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-10 Despite this, Car and Driver reported in their testing that the E55 AMG was faster than the SL55 AMG.http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-11 The E55 AMG was the fastest four door car in Mercedes-Benz's lineup at the time, being quicker than the C32 AMG and S55 AMG, and it posts faster acceleration than the 2003 http://en.wikipedia.org/wiki/Brabus_E_V12 biturbo (verified by the Guinness Book of Records as the fastest saloon car in the world at the time) as well.http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-12
The supercharged 5.4 L http://en.wikipedia.org/wiki/V8_engine was mated to the Speedshift http://en.wikipedia.org/wiki/5G-Tronic, which has a torque capacity of 796 lb·ft (1,079 N·m), as the newer http://en.wikipedia.org/wiki/7G-Tronic introduced in 2003 is limited to 542 lb·ft (735 N·m), not enough to handle the torque from the supercharged V8.http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-insideline1-13http://en.wikipedia.org/wiki/Mercedes-Benz_W211#cite_note-14

722.643, yep.

I am not 100% but you should be able to just throw in the different components. Ask importlab what he did. He's way up there in power. If his trans hold's, yours will.
