Eurocharged V5 Tune Review
You start to notice more of a difference starting at 4000rpm, but it doesn't become pronounced until you pass 6000. Most of the gains are 6000+. Below 4000 not much difference.
I would recommend not downshifting into 2nd or first merely from a drivetrain standpoint (just as you would never downshift into first in a manual transmission car bc the drivetrain shock is more).

If you are saying there is a diff from V4 to V5 in the powerband, I need to go sit in my car and get some, because I have yet to really hammer on it since I upgraded to the V5. I need to run my buddy again in his CTSV, that will be a tall tale sign as I seemed to pull him down low and through some gears, but come top end he appeared to be closing in just a bit.
If your claims are correct, I should pull him throughout now. Man I am anxious to meet up with him again!!!
So this V5 is not only the aggressive blip throttle?
That cannot have any advantage in a drag race, which is what most of us here enjoy.
Can someone with the V5 get their car to a track and give more feedback.

yeah... and this is why we need data and not butt dynos.
I'm not "hard up" on anything. I'm pointing out that members talking about their "feelings" when it comes to tunes is hugely inaccurate. This member felt it was faster in the top end when it clearly was not the case.
I can look at stretched out dynos all day, but it still doesn't tell me what the hell the tune is doing. I want to know what these tuners are altering and how it affects the engine. I want numbers and logs, not theory and dumbed down explanations. It isn't unreasonable to want to know what you may potentially be buying.
a consumer cant even make an informed decision as to what tune is best with just dynos and "feelings". This isn't an attack on v5, but rather pointing out a general pattern on this forum.

plus before with V4 my 4th gear only pulled to around 180-ish before shifting to 5th..now it pulls to 209km before shifting into 5th
tofo what are streched dyno sheets? I mean I have a few dyno sheets, no one here has "logs or numbers" ??? they've sold over 7,000 ECU tunes for the C63 and OE,Velos, whens the last time you saw someone with a messed up engine on here from a tune? I own all the tuners, Velos is really agressive, OE is agressive and drivable, and the new EC v5 is very similar to OE's tune, I've driven my car with a tune and a blown purge valve and a blown intake manifold and had no other issues (manifold and valve were screwed up when I bought the car)...i can tell you right now i beat on my c63 harder then 95% of people here..I TRY and blow my c63 up, because then if it does I'll take it into mercedes and tell them to build a better engine.
There is a difference in V4 to V5 ..like I said i don't think it's more HP, I think it just is ultilized better now

I will say however that shift points seem to have changed as I described in my review thread.
After an email response from Jerry, I understand the V5 to include the blip and shift point strategy upgrades. I take this as adjustments made to better utilize the power output and putting it to the ground in a more efficient manner with regard to better shift points. At least that is what I justified in my head.
theres no secret sauce here. Even Cobb publishes what they're doing. This is the first platform I've been with where everyone just buys blind. It confuses the hell out of me.
knowing what a tune does won't hurt your business. It's just another way to advertise that yours is safer and more drivable than the competition, with proof to back it up.
secrecy promotes lazy tuning.

Do this
1. Turn the igniiton key to the "on" position which is just before you crank the engine to start.
2. Press the accelerator to the floor and hold for 5 seconds.
3. Then turn the key to the off position but do not remove the key, then release the accelerator.
4. Wait at least 5 minutes, the ECU is then reset.
The ECU rest procedure only erases the adaptive transmission and throttle settings. It does not erase any of the fuel, timing or other programming.

), can someone take a second and explain the "adaptive trans and throttle settings" that reside in the ECU as well? They differ from what is affected by the Eurocharged tune, I gather? I'd also like to learn about the file types (and the ECU in general for my '14 C63) that I dealt with while adding the tune: there was an .abl file IIRC (to update mygenius I think), a MYGFile.fpf that the mygenius pulled off of my car, and then the V5-Tune.MYG that Eurocharged emailed me which I then uploaded. Can someone provide some info (or a link) on what each of these do, how they relate to each other, more broad ECU architecture (again, the adaptive trans/throttle stuff), and finally how to flash back to stock ECU settings?
Lots of questions but I'm a curious person. Many Thanks as always
i just updated to v5 from v4... and i'm not really understanding the difference... does this only come up after driving spirited? or just normal driving in S mode show this downshift blip...
i might just be confusing one thing with another... but even before v5, when driving aggressively in S mode, and then slowing down hard or braking... the car downshifts and makes some considerable noise when it's shifting...
so what difference is this blip to the normal downshift?
