no one really knows, whats longevity? 5yrs? 10yrs? C63 hasn't even been out for 10 years so no one even knows if they are solid without a tune long-term.

I've had all 3 tuners, let's just say my engine runs better now then when I first bought it

 

Eurocharged, how much to upgrade for people with a v4 already.

I currently have a v4.

Thanks,

 

The beast is unleashed that was the ticket to unlock the secret powers. Worked like a charm . Took it out this morning and dam you can feel and hear the difrence. . The down shifts are loud and insane. People walking down the street were looking to see what was about to exhale them .. Thank you

 

Glad i could be of some help..... Enjoy the beast .... Cheers

 

Reflashes for updates are free if you have the handheld programmer.

 

i think i've logged over 30k miles on the v1 - v2... and then over 60k miles on another c63 with v2-v3-v4... don't have the v5 yet... eurocharged has been around for a while with the c63 so i doubt there will be any issues... especially if you're going to stay tune only... i've got catless headers and exhaust with the tune and my car is still running reliably...

you also need to consider the fact that most of the power is coming from the potential the engine already has in it... since it's detuned from the factory...

 

Anyone with a P31 and a V5?

I ordered through the memorial day deal, I have a 2013 P31 trying to get some input on it.

 

Yes and its epic, check my review

 

How do you get hold of the v5 tune as I currently have the V4 plus my genius

 

Send Jerry an email. He will respond with the updated tune. I just received mine.
Thanks Jerry!

 

Asked for my V5 update this morning - received my update this morning - flashed my update this morning! Thanks Jerry! Your customer service is impeccable.

I have only been on a brief city drive so far so I didn't have a chance to really push the engine to get a feel for some spirited driving but the downshift blips are heaven!

 

Asked for V5 2 days ago and am being told to be patient since they have hundred's of upgrades to do. Different customer different kind of service...hmmm

Edit: V5 tune is in my inbox :-)

 

What octane do you guys run on your tunes? 91oct or 93?

 

93 octane (Georgia) v5 tune on stock exhaust, non P31. Just amazing!

 

You must get the V5, it's basically SLS black series sound, it's freaking awesome.

 

I'm also curious if the V5 tune is worth it on the p31, I know this topic has been beaten to death but just wanted to hear some on car experience from any p31 owners.

Also, I'm very curious about the talks about aggressive downshifts. When you drive in M mode, downshifts are already loud as hell stock, especially when you drop gears earlier. So I'm kind of confused how downshifts are affected by the tune in M-mode since loudness is really up to the timing of the shift isn't it? Also, more generally, could someone explain how the tune affects exhaust noise?

 

Here is a short Youtube clip with my C63 V5 tune. Stock exhaust.

 

nice estate!

 

sexy - nice work!

wish we had wagons in the states....

 

Wrong thread

 

How about some empirical data and logs as to what this tune actually does?

These reviews are fun to read, and i appreciate them, but they all follow the same pattern. Your ears and butt aren't good indicators as to whether an engine is tuned properly and safely or not.

Stretched dyno graphs don't count either.

 

damn stock exhaust is loud on downshift...my straight pipes must make peoples ears explode yolo .. it sounds so quite from inside the car, you always forget how loud these cars are out back

tofu - then how do you get data? The engines are fine with the tune, the tranny is fine too, if the trans can run a stage 2 blower for 1yr+ fine..a simple little blip is nothing ..idk why people worry so much on this forum lol, yeah it's an expensive-ish car (not really though you can buy a 2008 c63 for almost 25k) but it's not going to blow up in your face when you're driving down the highway if you have a tune

 

Outstanding review, OP.

I bought the MyGenius handheld device + tune from Eurocharged nearly a year ago but haven't installed the tune yet. I think it is finally time to contact Eurocharged to get the ball rolling. V5 sounds like a beast.

 

I just installed the V5 update from V4. The updated file installed flawlessly. I will write a review once I get a bit of seat time.

 

Have done but no reply yet, I can imagen they are extremely busy so ill just wait my turn
