The power 6000rpm+ is definitely more aggressive and it really does pull like a freight train nonstop to redline whereas before power would tend to taper off a bit before past 6500 even with V4. You don't notice the taper until you get the V5 and realize just how much the top end was missing.

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).

 

I am a bit confused here. Are your claims the differences between oem to V5 or V4 to V5?
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!!!

 

I didn't notice any more power V4 --> V5.

 

Sorry, very confused here.

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.

 

according to EC themselves, this is a blip mod only.

 

yeah... and this is why we need data and not butt dynos.

 

If they are claiming blip mod only from V4 to V5, why are you so hard up on dyno? Look at the V4 dyno if you want numbers as they are claiming no hp gain from 4 to 5.

 

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.

 

Theres a difference for sure..tested it a few times now, V4 seems sluggish after 5-6k RPM like someone said above, V4 also doesn't seem to launch as fast when you WOT it, it's not my mind playing tricks on me..maybe not more HP, but maybe ultilizes it more..maybe having "CEL" with V4 was the reason why

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'm sure tuners don't want to broadcast their tweaks for business reasons.

 

I get what you're saying. I personally didn't think a whole lot into it because no hp gains were to be associated with the upgrade.
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.

 

Really? That can only be attributed to rev limit increase.

 

Seems a lot could be cleared up with an explanation from EC.

 

Hey guys, I'm on V4 and requesting the V5... But question, what is a "blip mod"?

 

Watch the vid above.

 

I cannot find a dyno for v4 either. The dyno on ec website shows v3. Or was there no increase from v3 to v4 also? actually what changed v3 to v4?

 

Graph or video?

 

 

Cool! Thanks!

 

Alright, as someone new to this (and enjoying my first EC V5 tune ), 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

 

can someone with V5 explain what exactly this blip is?

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?

 

Anyone feel "misfire" type feelings from the car after tuning? I bought my 2012 with v5 tune and thought it was misfiring. Flashed it back to stock file today and it smoothed out. Any suggestions? Normal?

 

Common on every platform after tuning. The weak links will show. How many miles on the car? Check plugs and coils.

 

17600 miles on the car.
