Any better recommendations Than The Renntech EVM?
The install was extremely easy. I think it took all of 15 minutes and that was with me going slow. I’m sure I could put another one in 10 minutes or less. Anyone in the Orlando that would like a second hand, don’t hesitate to reach out!
First Impressions: WOW. What a sound at startup. And it keeps a really nice deep grumble at idle that goes with the German muscle car image. Coming to the GTC I felt it lacked a bit of the sound theatrics compared to my 911S at low speeds (no comparison when you’re getting on it in terms of speed and sound) but I think this solves it completely. Needless to say, I’m super happy with the mod.
Thanks so much!

With those two posts you should have enough info to do the install. Everything you need is in this thread.
Having just finish this install, let me share a few notes that might make it easier for the next person.
There are three 10mm hex nuts holding the floor panel in place. The two at the bottom are easy to get to, but the one at the top is deeply recessed and requires either multiple socket extensions or an extension and a deep well socket.
The cover was stubborn to remove, I had to man handle it to get it off, including some bending and cussing.
The multi pin connector has a levered locking mechanism. The lever is light grey as opposed to black and must be operated to get the connectors apart. I strongly suggest carefully examining and operating the lock on the new module because it has a small plastic tab to keep it from opening accidentally, and figuring out the tab on the one in the footwell would be a challenge.
When you remove the 10A fuse to install the power cable for the module, there is a slot in the plug next to the 3A fuse that you must put the10A fuse into. So there will be TWO fuses in the adapter when you plug it back in.
There is a good ground just forward of the speaker against the right side. It also requires a 10MM socket.
I found the easiest way to replace the plastic cover was to put the top threaded bolt through the hole in the cover first, then push the bottom of the cover forward until the two bottom bolts line up.
Replacing the top nut requires a method of getting the nut to stay in the socket while you are affixing it. If you take a 1" square of paper towel and put it over the socket, then force the nut into the socket, the paper will hold the nut in place and you can start it by hand holding the socket extensions in your fingers to start the nut, then pulling off the socket and retrieving the paper with needle nose pliers, then finishing tightening.
And credit Orcblog for this one, you can program you garage door opener in the car to operate the module, and you can also purchase cheap replacement remotes from Amazon. However you must have one working remote to clone from or you would have to repurchase the entire module. Mine came with only one remote so now I have a spare.
also, can you share how to pair the ASR remote with the garage door opener?
thanks in advance!

While this is the default, you can start with flaps open...
1 With your foot NOT on the brake pedal, press the start engine button twice.
2. Select your desired mode. Sport+ or Race mode which will both start with the exhaust flaps open.
Note that the mode button will only be lit after pressing the start engine button twice.
3. Put foot on brake, press start engine button and the car will start in the mode you selected.
If you selected Sport+ or Race mode, the car will start with the exhaust flaps open.
Hope this helps!

I can go into my garage right now and it will work.
I have a 2016 AMG GT S.
Are you sure you are pressing the start engine button twice and waiting for the mode button to be lit, then selecting the mode, prior to starting the engine?

I had a W205 C63 before and after the dealer applied a new software update, it was much quieter than before (I think bc they close the flaps even more).
My GT (2017) is not getting any Update anymore from the Dealer now
Btw: The ASR Module also makes the car louder while "normal" driving. Under full throttle it's not a difference i think.
But definitely worth the money.
Best,

Thank you!
Thanks. Makes sense. I thought I had seen some wording on the Renntech web site about issues with DMV emissions. I’ll give them a call.
