2014 E550 4.7 4Matic biturbo ECU UPGRADE/ FLASH
Has anyone done an ECU upgrade only and what were the results? What was the procedure? Are you happy about it? I feel like there a lot of lag when trying to pass even when in Sport mode.

Two years gone by and no tune? There are several tuners now who can offer handheld OBD tunes that will modify your ECU. They weren’t around two years ago. Renntech, Eurocharged, etc offer tunes that boost the HP above 530-40 HP. The only reason I have decided not to tune is the Transmission limits the torque available in 1,2, and 3 gears. The car from 30-130 becomes a monster, but not much gain from a dig. You could tune the tcu to change the torque available, but then you are playing beyond what MB designed as safe.
these cars are stupid fast as it is and mine is running like a beast already with the normal 430HP. There has to be something wrong with your car and you should start by figuring out the problem before spending $2500+ on a tune.

Wow, first answer in two years. No I have not did any modifications to the car,I have only driven maybe like 10,000 miles. I’ve always wanted a faster car but now I am considering of whether to do an ecu/tcu upgrade or just upgrade the car to newer model that has the new technology and design. I’m am definitely a MB fan and I know they are reliable if treated right. As I am getting older and larger I am thinking of swapping it to a S class 2017 and up. But now I’m intrigued, what kind of hand held tuners are available, I always thought I should remove the ECU or TCU and send it to Weistec, rentech or eurocharged.
please enlighten me.

Lag? Hah! what are you coming from, a Ferrari or something? The E550 already has more power than can be used in reality, so I never thought the risk of a tune was worth it just to say you have XXX HP to your buddies.

Worth tuning it, for passing plebs in the highway. 2014, and up have the AMG upgrades over the 2012-2013. If you take off the middle engine cover, and see a mini coolant reservoir, you have the turbo coolant upgrade, You probably have the same trans as the AMG's which lack a torque converter can easily find out with Lastvin.com
One thing to do though. Upgrade your brakes with Brembo rotors and pads. Your stock ones may be ok, but my Zimmermans were junk. 2012-2014 have the same Brembo calipers, but the rotors and pads are a different part number.
Also even if you don't tune change your Camshaft magnets, and sensors.

I’ll check the reservoir behind the engine cover.
I did notice on the brakes that have the Brembo logo. Car stops like it hits a wall. I was always amazed by the stopping power on the car. As far as camshaft sensors and magnets don’t know to much about them.

No Ferrari here but I had a Porsche a few years back. The E550 is faster by any means. The lag is in the transmission on kick down when changing to lower gears, does not engage instantly.

Turbo coolant upgrade. Check
So, @S. Madman, what are we looking for to confirm the AMG transmission? My VIN Datacard is attached.
Thx!

The reason you don't get the instant downshift is because your trans has the old people tune on it. If you get the TCU tune the downshifts are race quick. The only people in the states (publicly) that are known to do it is a contact from Eurocharged.
I am not advertising them, because they did not wanted my money when I was throwing it at them. But that is another subject. I may get it done soon, but before that I am upgrading the trans clutches, and drain pan with Weistec's stuff.

2 things:
1) reset shift adaptations, then drive like hell.
2) when you're cruising on the highway and want to pass, hold the down shift Paddle for a few seconds and it will automatically select the best gear to accelerate.
Also use sport mode of course, I find it pretty aggressive, I just use normal "eco" around town 90%
