Paid my money yesterday morning. Jerry sent me the tune in the afternoon. Great service. After installing V7, seat of the pants felt faster in comparison to V6 and exhaust sounded a bit louder as well likely due to power coming on sooner. Plus nice sounding downshifts. Thanks EC.

I think it's mainly more aggressive throttle mapping that makes the car feel more powerful.

Mazspeed

Well the thing is, it either has more power or it doesn't.

BalanBro

Even is the car is making 5-10 more HP, no one is going to feel that. People will absolutely notice the throttle response difference which makes it feel faster when driving around normally. I don't particular care for it because it screws with cars that have a nice linear throttle response and makes throttle modulation more difficult. I actually prefer the OEM throttle sensitivity over the V7.

I couldnt agree more. I had some issues regarding this and I found that pedal was too sensitive. I found that the requested load (if that's the term?) wastoo high in low rpms which results in an overly sensitive throttle pedal. I found that the car fought itself in C or S (engine vs trans) as the requested load would be 100% under light pedal pressure but the car is trying to shift smoothly, below 2200rpm. It felt like in low rpm [1200-2500rpm], 15% pedal = 100% throttle body.

I unplugged the battery overnight and it helped. Smoother drive and shifts are much better. I would suggest doing that.

So the pattern im seeing here is everyone is disconnecting the battery and everything is getting better , but how long does that last ? .

gtracer

Forever since the car readapts to the new values.

Lol at unplugging the battery ....keep beta testing guys

Ok, I drove the car on a longer trip today, and taking off from every stoplight it acts as though the transmission was slipping in from 1st into 2nd and 2nd into 3rd at light to medium throttle in C and S modes. It also felt very "clunky" as the car was downshifting while coming to a stop. My wife even asked me, "What is wrong with your car?" She didn't even know I had done anything, so there's some blind feedback.

For the record, I did the install procedure exactly as instructed and even disconnected the battery terminal for over 12 hours to make sure all adaptations and ECU fuel trims were reset. Got to reach out to Eurocharged about this. I'll keep everyone in this thread posted.

oggie

Try unplugging the battery and leave it for 8 hours or so. Some people did this and was able to resolve the driveability issue.

BalanBro

Did that already for 12 hours. Didn't work for me. I just uploaded a new file from Eurocharged. I'm gonna try that over the next few days and see if there's any improvement.

How did you get on?

BalanBro

To be honest, I don't know yet. I brought the car in for service shortly after and had reflashed the OEM tune. I've yet to flash it back to the V7. I will say that the OEM file definitely drives better when you are just cruising around town. I'm gonna keep it it like this for a while so I get acclimated to how the car drives normally. That way I can tell definitively if the new tune file is giving me issues or not.

I uploaded the tune and was able to reset all the ECU and TCU adaptations on an Autel MaxiSys. Power delivery is great when you have traction.

I suspect you guys are having adaptation issues as Jerry has said.

shaun.barnard

Won't the old TCU reset trick work then instead of disconnecting the battery for so many hours? The procedure where you put the key in position 2, depress the accelerator, turn the key off while depressing the accelerator for 5-10 seconds after switching off? Just a thought as that procedure resets the TCU so the TCU can re adapt to a new driving style. Worth a try?

BalanBro

Has anyone confirmed that the TCU reset actually works on the w204 including the Facelift? I tried this a few times and never felt a difference afterwards. The fact that there is no confirmation afterwards certainly doesn't help.

sirius9

TCU reset doesn't work. Its proven on STAR diagnostics.

Just got my V7 tune yesterday and uploaded it to the ECU, no problems at all. My car is stock except for K&N filters and secondary cats replaced with straight pipes. It was immediately noticeable when I started it and gave it a few revs, like a super-bike compared to what it was and I must say gear shifting is smooth but the kick down throttle blips are crazy, really sounds and pulls awesome now.

SactownP31

Why do people say their car is stock except for this and that. Guess what, if you gave it a performance mod it's not stock. It's like a chick saying she's a virgin but she has...........

Ludedude

shaun.barnard

Doesn't mean that because she's a virgin she hasn't done a few "jobs" of some sort before

skratch77

They are talking about stock tuning on the car

ertimark

Hello,

Looking to get this for my '14 w204 coupe. Can I go on and purchase the actual version of EC? What are the current feedback? I am located in Europe, so this would be a purchase from a UK dealer called 'MSL Performance' shipped with the MyGenius device.

Replies are greatly appreciated.

If your car has a LSD in then I would say go for it. If it doesn't then I would first do the ls diff mod. I fitted my Wavetrac after the tune and it was like adding a double tune. An open diff doesn't give justice to any modified tune. I've read posts about guys saying that a lsd conversion was the best mod they could have done first and I thought they were talking nonsense until I had my ls diff installed. Now the car makes much more use of the tune, the handling is much better and much more predictable. Hope this helps.
