Horrendous lag time between shifting into gear and being able to move. Tune fix?
I have noticed that unless you VERY frequently do the TCU reset, these cars have a substantial lag between shifting into gear and actually being able to move. To a degree to which I feel borders unsafe. When I'm backing out of a parking spot and shift into gear it is 1-2 full seconds before the car will go forward. If you don't baby the gas, it lurches. I had to do a u turn today on a semi busy street that was narrow. This lag made the 3 point turn really sketchy when in any other vehicle I would have had ample time. It chirped the tires as I'd mashed on the gas forward due to oncoming traffic.
I know I'd read that some firmware updates improved this, but I'd prefer to not pay the dealership the couple hundred dollars they want to do so.
I'm curious if instead, I could install a tune from OE or Eurocharged and if it could/would permanently resolve this problem and allow me to address the issue while adding the benefit of the tune itself.
I will have a mygenius tuner in my ownership in the next week and could send it off to one of the tuning companies to load up. (unless I can purchase a tune remotely, load it onto the my genius flashloader, than install it onto the car). I know I could do that with my SCT on my old diesel truck, the tunes were just emailed to me.

there are a few software update units on ebay , that come with a flasher and the software itself (you can flash it and if you decide you can flash back to original) , i remember at some point i almost bought one.
idk how reliable those are , and if they fix that "issue" but they a lot cheaper than OE and Eurocharged

I miss the instant feedback of moving the shifter into position and feeling the transmission engage right away. This electronic shifter is like pushing a button and waiting for the elevator when you know it's on your floor. I expect that with an elevator but not a transmission. It was better on my Prius as you could move right away. Thankfully, I am not in many situations where this matters. But I have had a few 3 point turns or parking lot situations where I found it concerning.
However, I didn't realize an ECU reset made it engage faster. Pedal response - yes, but thought that was it.

2014 E63S; AMS 100 octane ecu tune; edok tcu tune; BB intakes; dyno tuned
Never had this type of lag ... 2016 e350, 2014 e550 x 2, 2014 e63s
may be a conductor plate issue
details on the car? Miles?

I've noticed this lag too and I've actually wondered how it would perform in a 3-point turn if I had to do it in a hurry. Luckily I've never been in a situation where I had to do anything quickly with the shifter. I'm interested to know if an ECU upgrade fixes that issue, but it doesn't seem like it would.

I can accept the brief shifting into gear delay, however the pedal response is where it become really concerning. Considering the ecu/tcu reset procedure largely/mostly removes this, I am curious how a tune could affect it. The long pedal delay and resulting surge of power once the car actually decides that you want it to move is far from refined of progressive. It's unlike any vehicle I've ever had.

I've heard really good things about the overall responsiveness changes from a tune. If a tune costs 400-500, increases hp and tq by 20-30, it's a bonus.. if I could resolve the pedal response delay issue, sans a trip to the dealer for a firmware update, I really think I could be onto something that would be worthwhile. It looks like I am getting a meisterschaft exhaust this week and a my genius flashloader is getting tossed in....

Sprint Booster does jack for this, and I'd caution against installing one (one left me stranded, and reading up on it, I wasn't the only one).
I took mine (2010 E550) to the dealer for this a couple of months ago. They said nothing is out of spec, but performed all the updates available for the transmission (for a couple hundred bucks) and nothing has changed. Looks like we just need to live with it. It drives me crazy, and I also think it's a safety hazard. I can shift, floor the pedal, and count the seconds out loud before I start moving. My loaner (2016 E350) didn't exhibit the same problem.

I'm sorry to hear this wasn't a good fix for you. It doesn't sound like this is a viable fix. I guess I'll try the tune route.

When installed correctly, which is really easy (as I recall from a different thread, a previous poster had "problem" with SB due to broken pins (obviously during installation) hence "warning"), I stand by the fact that SB does exactly what its suppose to, at least for me, which is to (almost) eliminate or significantly reduce the Drive By Wire throttle lag in non-AMG MBs. Had it in six different MBs with zero issues: 2003 SL500, 2010 E350 and E550(coupe), 2012 E350, 2014 ML550 and 2014 CLS550 (the last two mentioned are impossible to drive smoothly without the SB). Interesting that both my 2014 (former) E350 and (current) E550 (both sedans) did not need it - never had throttle lag in either of the 2014 E (had E350 for only 6 months so maybe it would have developed it in time, but E550 now for over two and a half years, and still zero throttle lag).

I should also add, the lag is less if I'm in "less of a hurry" if that makes sense. With very subtle application of throttle, the car will slowly reverse, or begin to accelerate like a 90 year old should... the long lag than sudden jerking/application of too much throttle that all comes on at once is more evident. This gets me lots of dirty looks pulling out of a parking spot in a crowded lot, long pause as I shift... long post waiting for throttle, than slowly beginning to move.... Ugh.

The problem with the SB wasn’t “obviously” due to installation, but a manufacturing defect. As you mentioned, it’s dead simple to install, and caused no issues for the first many months it was installed. It also didn’t do anything to eliminate the throttle lag issue. If the SB works for some users, that’s great news (http://www.iflscience.com/health-and...-are-placebos/). This paper does a pretty good job explaining what the SB does (and does not) do: http://www.crosslake.net/~dbipes/spr...intBooster.pdf The white paper states: “Sprint Booster does not improve throttle response or acceleration.”
As others have posted, we can floor the accelerator, and count seconds out loud for something to happen. The SB just makes it so folks don’t have to press the pedal as far or as fast on their own, something I’ve never struggled with doing.

I know exactly what SB does (and does not do). For me it eliminated or greatly reduced throttle lag not in just one, but in six different MBs (as mentioned before, my '14 CLS550 has a long throttle delay, as was '13 CLS550 I considered before I bought '14 three years ago). And no, it did not make car quicker (its not supposed to), but it did make throttle "engagement" immediate (or very close to it) so that pedal's response felt immediate to me and many others. (Five years ago I was very skeptical myself...until I tried it).
IMHO, a SB is a must on most if not all MBs until and including 2014 MY (except in my experience in both '14 E350 and E550 - they must have done something to "fix" the issue for 2014 MY specifically on w212 Es, so for E class its 2013 MY and earlier).
Disclaimer: I usually change cars often, so the longest I had SB in were the 2014 MY CLS550 and ML550 (over 18 months) and since I sold ML, I have SB only in CLS now, so I do not know its longevity, but do know that physical SB P/N SBME0012S (the one for E and most other "modern" era MBs) has changed form the ones I used in 2010 and 2012 cars (even though P/N is the same).
This is the "older" version I had in 2010 and 2012 Es: https://mbworld.org/forums/attachmen...12s-fjls1x.jpg
This is the "newer" version I had in '14 ML and still do in '14 CLS:
