I don't run cats...

Jeremy isn't 100% right with that.. it's more that when it changes gear it leaves the fuel on and kills ignition or retards timing to kill power for a second while it gets the next gear. It gives the same result though...

So, just a heads up for all those P31 owners out there.. I decided to give the Eurocharged V3 flash a go on my new 2012 with P31. with 1200 miles on it.

Not even my optimistic butt dyno could tell the difference between the before and after.
So i took it in to dyno. Yep my suspicions were confirmed. I reached out to Eurocharged on Thursday last week sharing the results with them and I am yet to hear back on any suggestions.

The car actually made less hp. well -1 to a +2 gain. I did about 6 runs 3 before and 3 after the flash and my last run with the brabus air boxes.

Good thing is that it seems that the brabus/ROW air boxes seemed to give me 9rwh

But as for the V3 tune.. hmmm no.. not so much.

I am hoping they will look into it for me as it might just be a faulty tune or something..

I will update here or start a new thread for those with the P31 2012's thinking about gettign an Eurocharged flash.

wow thats horrible. I have a P31 2012 coupe and was looking to get it tuned by EC after the break-in but it seems there are a lot of issues with this tune

loungn14

what were the conditions of your runs? Can you post or email dynos? We have tuned many p31s all with positive results Did you apply the tune correctly? -1 to 2 gains sounds like the same stock tune

lot of issues??? really???? care to elaborate on that one?

The P31 tune is already a strong tune - not much (if anything) to be gained by going aftermarket tune-only on a P31 car. This has been tested repeatedly by owners - I don't think there are any independent dynos, nor 60-130 tests, that have shown a marked improvement with any aftermarket tune thrown onto a P31 car. If it's happened, at least, I don't recall seeing any.

If you do major hardware changes (headers/exhaust, supercharger, etc.) then of course an aftermarket tune to optimize everything, makes a bunch of sense.

The OE tune is stronger than the EC tune and even then a P31 car showed gains on the dyno but not much in the real world. (1/4 and 60-130)

we have seen as low as 17-18 to as high as 31 on the p31 cars...(good mid range torque as well)

propain

Meh... Dyno numbers... P31 aftermarket tuned has shown little to no gains in real world conditions on multiple cars.

Davo81

Are you sure the flash worked?

Davo81

FIGHT! FIGHT! FIGHT!

Hold your horses here...

I had some trouble loading the file.. as I stated, there might have been a problem with the file for my car.

I still believe Eurocharge can and will make a difference.

we know the p31's are a tad different and the margin is much smaller.

Sorry, i did not mean to post this as a flame as I KNOW that each car is different and a company is judge on its customer service as much as its product. And I have by no means given up on them at all. Great thing here is that we have a programmer and the potential of only an email away for fixing things.

As for the stats.. I had it on a Dynapack dyno as I intended on getting a cutome tune and they seem to be by far the best bet for getting the most constant number.. and it did.

I ran 3 runs stock and they were all within 3 hp from one another and 3 runs after the flash.

I know the flash took as the AFR immediately and constantly upped from 11.461 to 12.284

We did have some issues with the dyno in running in 5'th gear.
So we ran in 4'th and changed the ratio in the dyno to make it 1:1

I am waiting for the full file still but they sent over the final runs.
Attached below. Problem is that they highlighted the highest and lowest.
(Problem is that the highest one was the last one with the ROW air boxes so it skews it a bit)

I have another dyno scheduled for end of week to resets as I dont like to trust a single Dyno

Weather Data:
Temperature: 75.3 - 79.8 Deg
Humidity: 29.5 - 30.3

Stock:
Torque: 392.76
HP 421.610
AFR: 11,461

Tune Only: ( Highest )
Torque: 393.055
HP 424.750
AFR: 12,284

Tune+ROW boxes ( Shown Below as the MAX gain )
Torque: 398.055
HP 431.762
AFR: 12,284







And as I mentioned above, companies are judged by their customer service as much as they are judged by their product.

And that means I have not at all given up on them.
On the contrary, I have 100% faith that they are going to come through..

2008AMG63

I disagree. killing ignition will create an explosion like sound.

2008AMG63

bump!

any news?

mucho waiting for my programmer

AzC63

I have a 2012 p31 coupe with EC tune. I haven't dyno the car but i actually do feel a difference in performance. Mostly in lower gears around 2 -4k rpm.

Dkmr

how many whp gain, you think,I feel a difference when i put on the xpipe,thinking about getting EC or OE,thanks

AzC63

I honestly have no idea on how much hp you can gain on a p31 with EC tune. All i can tell you is that i have gone back and forth between stock and EC tune and i can for sure tell a difference in lower gears. The car pulls harder around 2 - 4k rpm to the point where i am getting a little wheel spin even with tc on. Not really see much difference in hight RPM though. If you already have an Xpipe , i would get a tune. Either tune should be fine.

pkarandi

Newbie here with a 2012 C63AMG Sedan...LOVE the car! I am going to buy the EC handheld programmer and the EC V4 tune...Also found out from Jerry that the V4 tune is stable and will be publicly available this Monday!

As per Jerry, faster/ smoother shifts, higher shift times! No dyno chart just yet but on the way!

Hasan Shaikh

This is interesting.

I shall also check with Jerry on what he is going to do for my car.

c35amg

help. i just got mine today and its not workin for me. ive done everything. update ver. an protocal an still nothin keeps giving me error code 0x3101. anyone have any ideals it would be apprciated. i just gave up an put it back in the box if someone has the flash for 2012 c350. can they email maybe mine is bad

2008AMG63

Great, I just received the handheld programmer!!

Now I have to read instructions and ask for my tune.... What kind of tune are you guys requesting?

2008AMG63

Are the available tunes listed somewhere?

andrew c230k

Just wondering if there is any data on fuel consumption pre and post tune on a 2008 C63

I was looking at 2008 C63 451hp vrs 2008 E63 507hp according to Benz they get the same fuel consumption

2008AMG63

That doesn't sound right.
To start with, E is much heavier than C.

andrew c230k

12 City 15 Combined 19 Highway

C63 3920 LBS
E63 4040 LBS

When you got that kind of power the difference in weight makes no difference...

All I want to know is if I tune my C63 from 451hp to 500hp like apparently is possible am I going to be spending more or less money at the pumps.

I don't need 500hp but if it gets the same or better mileage I'd be interested.

2008AMG63

WOW! I always thought the C would be much lighter! ... I meant that weight affects consumption.

Obviously I cant answer your question. But it's worth mentioning that some people reports better fuel efficiency with the tune.
