Rebellion throttle response system

Some one on this forum has installed the Rebellion Throttle Respons sysytem o their AMG 45.
Throttle Response System for the A/CLA/GLA 45 AMG - Rebellion Automotive

Can you tell me how easy or difficult the install was, and how seamlessly it affects acceleration and response?
I'm eager to try it, unless my dealer can update my tranny software to fix the hesitation.

Hello bikerbob

I put a Rebellion stage 1 tune in my 45 and it fixed the throttle response, its a lot more cost but its a lot more power >
the tune is pretty easy to fit if you don't have fat fingers :|

 

To bad that company didn't seem to post any power charts to see the before and after, that's something that'd help us and them sell the product.

People want to see those details.

 

This has become a repeatable issue for me at this point. Dealer requested video which they have sent to MB.

Here's what happened last night; GLA had been parked in my garage for about 12 hours. Cold engine, cold transmission. Started, shifted into reverse, gave it gas and nothing. Shifted back into park, waited a few seconds, shifted back into reverse and had same issue. Dealer suspected maybe the parking pawl wasn't disengaging, but as you can see from the video I'm actually moving backwards ever so slightly.

Because the shift is usually violent (you'll hear my tires chirp here), I was feathering the throttle slightly until it engaged. You'll know when it finally shifts

This is getting really frustrating and I hope MB gets back to me with a solution soon.

Does it void warranty?

It's cheap enough to be tempting for a try but I am not sure if there are big risks with it.

Like almost too good to be true?

 

mate they will look for anything to void the warranty but if i caused an accident because of NO throttle response i would be going to see some (NO WIN NO PAY)lawyers
The main reason i got the tune was for the NO throttle response

 

What I've been reading seems to imply that they are not specifically looking for tunes. In other words people go in and get mundane warranty work with no ill effects because they are not checking for tunes as part of the process. I have yet to find an instance of someone getting major work done such as a blown transmission with a tune and seeing if they skated through or not either here or on the CLA forums. It is very possible they have ways to check this that are not used in the normal day to day. I've ran into a couple instances of cars that used mechanical means to measure rail pressure (a simple pop off valve that let go at a preset pressure) and one that measured boost (a secondary boost meter) both of which were built into the engine to detect tunes. Does the Merc have similar? I don't know, haven't seen proofs to indicate either yes or no. It is important though to remember that the proof isn't out there till the first guy goes down in flames and reports such on the internet. Or not.

To be sure, remember to take the thing off before you go in, several people have reported having their car flagged by MB after going in with a tuning box and what that means is usually a voiding of the warranty on the entire powertrain. If you want to play the mod game the conventional wisdom is simple. You should be capable of and prepared to be your own warranty station.

 

GLA is at the dealer again this morning. The lead tech, shop foreman, and Service Manager all saw the new video and said "yup, that's messed up".

They are sending the video to MB and gave me a fully loaded GLK while they work this out.

 

Transmission shifted into limp mode twice in the last 10 days. Both times traveling over 70 mph in the rain and floored the throttle. I had to pull over turn the car off and back on then everything ran fine except I have a check engine light. I checked the oil, coolant gas cap. All of those are fine. I have an appointment next week has anybody had a similar issue? I have about 12,000 miles on the car

 

UPDATE: Spoke with the dealership this morning. The said since my last visit a few weeks ago, there was a new service bulletin from MB and they are pulling my transmission to "replace some parts". The service advisor couldn't tell me what, but I plan on finding out (as well as getting the info on that bulletin) when I pick up my GLA on Wednesday.

 

Another update (for those who are interested):

My GLA got a new clutch yesterday. The labor to replace it was.... extensive.

That is wild - don't try this at home

 

And I just got off the phone with the tech. There wasn't actually a bulletin, but MB has had multiple cases with rough engagement. The solution is to replace the dual clutch.

 

Wow, at that level of disassembly, I would highly question whether the dealership techs will get everything re-assembled exactly as factory built. Especially if they're getting paid flat rate for an engine/transmission R&R. Would take an experienced, skilled and conscientious tech to do it right. Hope your dealership employs that type of tech.

 

I've had a personal relationship with this dealer for 12 years. The thought of them assigning a project like this to some bonehead tech never even crossed my mind.

 

My dealer visit revealed a code for a misfire on cylinder number 1 see report enclosed.

Oh and I should mention there is a noticeable difference in how smooth the car shifts. And of course, no more violent clunking when shifting into reverse

 

My car is in the shop for the same thing . It's been in for over 20 days for dual clutch and electrical plate in transmission. How was your car after they put it back together. I'm nervous it won't be like brand new! And is the fix better for you now?

 

Well, after the second download of the new software I had the same issue, but now the reverse is also affected. I managed to capture the transmission slipping and sent the video. Now it's in the shop and awaiting for the diagnostic.

Have a look at the video:

I also had my dual clutch replaced and fixed problem . So far so good , drives 100% better now.

 

Glad to hear they got it fixed for you. Bummer it took so long.

My GLA has another thousand miles on it since the clutch replacement and it's still running smooth. Talked to my Service Writer last week just to let him know things were all good and he said there still isn't a recall notice or TSB that points to an ongoing issue.

However, the tech who worked on my GLA said he was able to find multiple similar issues on his internal tech forum, where replacing the clutch is the solution.

Long story short, if it's shifting rough bring it in. And of course, video helps. I know for a fact that MBUSA has my clip on file.

 

Oh and here's the video I sent to MBUSA that got the dealer to replace the clutch:

https://youtu.be/gLN7KPGXYb4

 

I hope this helps everyone out there , I know I was struggling with what to do. This forum has helped a lot . The more people that share the better for all of us .
I still love my car .

 

do0 you have a phone number? My dealer hasn't heard of a service bulleting for this issue.

 

That's because there is no service bulletin for this issue. It's being handled on a case by case basis.

I was able to get my problem addressed quickly because I had video, and the tech was smart enough to look on the internal MB tech forum they have and see similar issues where replacing the dual clutch solved the problem.

 

IS there someone at that dealership I can contact. My dealer can't find anything about software updates.

 

I called MBUSA about it and they even came to dealership to see it and told me they had a fix for that exact problem , which was the duel clutch. The head mechanic should know about it and contact MBUSA. They know about the problem .

 

Any contact info or telephone for head mechanic at your dealership. My dealer and the local MB field rep were unaware of any fixes at all. Normal they say.

 

After the 5th time in they finally are changing the dual clutch. I have lost confidence in the product, not sure if I want to stay in the GLA or change to the GLK. Dealer is looking at options, but since it's my first MB, not a very good first impression!

 

I feel the same way after having the same thing happen to my car

 

Sounds like a dealer problem, trying to fix it so that they don't have to give you a new part.
