Just want to share my experience regarding the EC tune I recently got for my C218, RWD.
Installed it about a week and half ago and simply love it. Though I get lot of wheel spin in 1st and 2nd gear simply because it is RWD, understandable. But it is a big difference in the pull and exhaust noise than stock. The mods I had before the tune was removal of resonator and both mufflers - replaced with straight pipes. Didn't get the X/H pipe, don't know why I missed that out, but will do that later this year with cat-less downpipes. The car was loud with straight pipes, mind you the primary and secondary cats are still intact, but it would go quiet above 3,500RPM if I floored it, every time. It would **** me off, I mean it's a V8, it should be louder lol.

So then I got the tune. Though it took about 3 weeks for the MyGenius device to be delivered, I was told they were backordered so I knew it will take some time. Did the thing with it, followed all the instructions, fairly easy. I got mine with the burble tune. It sounds awesome now. It pulls hard.

Now the exhaust issue I was having that it would go quiet after 3,500 rpm...is gone. It now feels like a mean little german muscle car. Though not the sound of an AMG, alas. Now it's loud all the way to the redline. And can't get enough of the pops haha. They come into play between 18/1900 - 3500rpm. It smelled for the first couple of days, but now the gas smell is gone. Guess the system takes time to cope with the big change.

I will post video of revs and pulls later as I don't drive it that often. And I am going to dyno it just to see how much I'm getting it at the wheels. Though I'm told it's somewhere around 470whp and 530-550wtq.


The only downside of the MyGenius device is that it is only compatible with Windows PC, which I don't have. I own a MacBook. I had to call a bunch of my friends and took me 2 days to find someone with a windows pc lol. Other than that, it works perfectly clean. It is a process, but the results are awesome. Couldn't be more happier!!!

If you guys have any suggestions/concerns/comments regarding anything...happy to hear

 

thx for sharing, looks awesome research ! congrats ...What about your video please ? can't wait lol

 

Yeah I'm lagging on the videos. Just been busy and that idea left my mind...was polishing and doing ceramic coating for 2 of my clients and got a flat tire on the c218 lol
So I will make a video once I get the new wheels on...they should be in transit. So a few more days and I will upload a video.

 

VIDEO VIDEO VIDEO!

 

Haha I will have the video up here and some pictures once I get the wheels on...probably by tuesday?. So far, im happy with it. Want to get cat-less downpipes some time in the winter.

 

How is it to return the car to stock tune? Have you tried that yet? I have a 2016 car still under warranty and I need the option to revert back to stock for the occasional dealer visit.

 

I haven't tried it, but the stock ECU file stays stored in the MyGenius device. But my friend who has a GL550, he has his under warranty and goes back and forth with the tunes when he goes to the dealership. Says it takes about 2 to 5 minutes to make a switch.
I don't have warranty so idc lol mine is '12.
You simply plug the device in and with a click of few buttons, the device will install Stock ECU file on the vehicle and you're good to go.
Or, someone I know, he simply bought a clone stock ecu for his cls. So he has a tuned ECU and a stock ECU. Says it takes just about the same time to switch back and forth and fairly easy to do so.

 

Thanks... good to know.

Who did you deal with at Eurocharged? I'll have to see if they have any sales going on

He sent me an invoice and I was curious about if I'm getting scammed online lol So I called EC and double checked with them if the invoice was legit lmaoo
I mean, no offense to Jake at all, I just wanted to confirm before I paid the 4 figure amount lol He will get you a deal in no time. Hit him up.

 

Any update on the video? Thanks.

 

BlackFriday sale maybe?

 

I have a 2012 cls550 with the 19" AMG wheels and the stock Perelli P-Zeros 40 PSI
How did you stop the wheel hop when I Mat the pedal it sounds like the rear is hopping like hell...

 

Anyone know what the EuroCharge Black Friday sale is?
