After installing ROW intake and AFE filters (almost a month now) I no longer have the kangaroo issue in first gear in S+

Just installed v7 and car feels bogged down and laggy at low rpms, Power comes at high rpms only. Also exhaust sound feels dialed down. I am hoping the car is going through an adaptation phase...

loungn14

yup. Disconnect the battery overnight please

Rabih75

After a few drives and disconnecting the battery the car got better. I guess it is still teaching itself the new algorithm but looks definitely on the right track. Thanks Eurocharged for the awesome service so far.

Rabih75

dyno’d 371.5 WHP on a mainline dyno (Australian) which is known to read lower by 17pct than a dynojet. Doing the maths I say I netted 512HP max at the crank. Got in touch with Jerry and he sent me a new file which I feel is wicked. Waiting for the Kleeman LTH before returning to the dyno for another run. Feels much better and I also love the burble tune... thanks Eurocharged, so far you have been awesome.

Hey mate,

Whereabouts are you in Oz?
I didn't know that mainline dynos read 17% lower. My car was dynoed on a mainline dyno and read 385WHP using an evotech tune.

Have to say most tunes all act the same. You will figure out
A way to play. Maybe start by setting the brake when your at a light
And figure out your concern. Manual mode will Help you figure out
How to deal with the added power also, or just floor it that’s the best way to figure things out.

I expect to load the V7 tune today. Curious how it will be. a lot of different comments on this tune pro and con.

Long tube headers with E85 makes a loud gunshot explosion at very high RMPs when flooring it and letting off the gas lol

I run 104 Sunoco Gt in my ride, that is one of the best sounds short of a high rev down shift.

Rabih75

I am in Dubai and went to simonmotorsport who use a mainline. Your numbers seem about right: 385*1.17(to adjust the discount of mainline)*1.18(to account for drivetrain loss)=531 crank horse power , close enough to what your tuner advertises... humidity, altitude and ambient temperature play a role as well and could explain some variances versus advertised numbers.

Are you driving the car in comfort mode?

Rabih75

installed the Kleemann LTH. EC V7 headers tune (with burble) was already on the car and working brilliantly as I explained previously ... until I installed the headers.
unfortunately, after headers and resetting adaptations, burble is now gone... car gains are +80 NM rwhp and 18 RWHP vs. stock. Weird to have respectable gains in torque and not in HP... Jerry is looking at the issue, could it be that the car is running lean? Thanks

I am tuned by Eurocharged and have no complaints. My car made 574whp on their stage 2 tune. if you want to make the most out of your tune and make changes I would recommend that you dyno the car and send the logs to Eurocharged. In my experience when a car has an aftermarket tune the throttle sensitivity is going to be altered. If throttle sensitivity is the problem you can get that changed as well but you may be making less power.

hachiroku

throttle sensitivity is up to the tuner. this will have nothing to do with fuel or timing as they are throttle mappings. if the tuner bakes that into their tune...it'll be part of their tune. same with burble. these two should not be affected by header install if the tune is done correctly.

i do have to mention though...factory mappings do have the tinniest amount of burble built in. that WILL be affected by fuel and timing.

p31c63amg

its the way your exhaust is set up. I’d start with the x-pipe, is the resonator out?

Rabih75

resonator is still there. Just LTH / primary cats delete.

Rabih75

did that today. Thanks for the advice. 574 at the wheels with just a stage 2 (tune, headers, filters) Sounds a bit high to me.

p31c63amg

loose the resonator and look at doing a x-pipe. I have a pic in my photos if your interested in what I did. I had a custom made one. We made a few types to check for the sound I was looking for.

PeterA90

doesn’t have anything to do with the exhaust. It’s the tuning. Stock cat back can flow 800+ whp. Xpipe should be closer to engine for the scavenging effect.

He has a stage 2 supercharger

p31c63amg

see

PeterA90

I have no idea what your talking about... it has nothing to do with the guys problem. The problem is his tuning. Not his resonator

Resonator delete makes power

so here is a recap of my case: c63 p31, with Lsd from 2013

- dynoed while it was stock on a Mainline load bearing dyno; 369 rwhp, 472 NM rwtq.

​​​​​​- added Eurocharged V7, Kleemann long tube headers, primary cats delete, K&N filters and dynoed it again today on the same mainline: 389 rwhp and 571 NM rwtq

gains: only +20 rwhp and a healthy + 99 NM in wheel torque...on a Mainline which reads lower than Dynojet by ~ 17% I am told.

This morning, I went for a real life test and did a few pulls with an 2016 AmG GTS stock (515 HP, 650 NM at the crank, 200 lbs lighter car with great aerodynamics and brilliant gearbox) - despite I was losing some traction in 1st and occasionally in 2nd gear (as my wheels are 2 years old and only 245s wide at the rear), I managed to stay very close to him...difference of Max 2 cars lengths in favor of the GTS after a pull from 30 mph until like 140 mph. We evened in 2nd and he pulled slightly towards end of 3rd and 4th.

A bit disappointed, as I was expecting that the promised tune and headers would yield much higher fire power than the GTS, resulting in a different outcome, but it is what it is.

The car sounds insane though, like an angry lion, when I push the throttle and is still usable while in C mode despite occasional outbursts of anger. I would certainly need to improve traction though, wider wheels and possibly Bilsteins...

As far as I can tell, the only anomaly from the above are the modest HP gains from stock. I sent Jerry a dyno log this afternoon and he promised to come back with a more refined file.

With this said, there is a caveat about my stock dyno results because the dyno pull was made after reflashing the car to stock...following a first iteration of V7 which the car did not like- so it is possible the car did not adapt fully to stock and threw a higher HP reading; who knows!

net, net I am very happy with my torque figures, little less with my HP and I think I am missing 30-40 WHP for some reason. Or perhaps this mainline dyno reading is simply unreliable. Hope Jerry solves this.

as I said before it’s not all in the tune. Your missing the point it’s not about the power it’s about the sound he was looking for. I assume you have the cash to just play with a fab guy to see what’s works best and countless hours on a Dyno to see the difference of what works and maintains What you make at the wheel but most in important is the sound while Fabricating your custom exhaust, I have that luxury,So I guess I will take the custom ECU tune out of 200k Porsche and have it changed so I can have the ECU Tune make my ride sound like I want, might as well take it out of three of my AMG rides too, is That what your saying. I can now see what you and Your pick have in common.
