Mr. J

I might be wrong but I think it's limited to 155 for cars that shipped equipped with the 19'' summer tires and 130 for cars that shippped with the 18'' AS tires. The dealer can change this is the proper tires are fitted. I think you can access it in the service menu too. I'll check tomorrow. Most ECU flashes delete the top speed limiter as well.

That's odd.. I got the 19" wheels, but mine is limited to 175mph

Update:

Eurocharged has reached out to me (albeit just via PM and nothing really substantial has happened). They basically want me to replicate the problem (which would involve me having to drive 140 mph and purposely overwork the turbos. If this is the incredible post-sales support they promised, I'd be cautious.

A lot of people have asked questions regarding how the car performs itself. The throttle seems a lot more sensitive and it does make it a lot more fun to drive. Eurocharged told me they would email me the dyno results for my runs when I got it tuned but they never did so I don't know exactly what the gains ended up being.

Can you show me exactly where we indicated you drive 140mph???? I would love to get this addressed and solved, but please refrain from posting information like we are purposely asking you to drive 140mph, overwork your turbos etc when that simply did not happen.

Here is what was posted for clarity...

Nam,

When they come on, can you please get your car scanned so we can see what the pcodes are so we can see if it is our tune causing it?? We are trying to solve your issue that you've posted in our for sale thread, but we need all of this information since we can't diagnose your car when it's not here or know what the codes are.


We asked simply for the P-Codes (multiple times) so we can help troubleshoot the error

aggies15

So I indicated multiple times that the issue occurs when my car is in the speed range. How else am I supposed to replicate the issue if I don't get it back to that speed?

aggies15

Please refer the the FIRST post I made in this thread before you decide to start sharing my private messages in an open forum. If you have any ideas on how I can replicate the issue without having to do that, I'm all ears.

Just a suggestion....If you got it tuned at eurocharged's houston facility, why not go back, put the car on the dyno machine and run it to 135+ until you get the over-boost CEL again. That way, EC can fix the problem in house. It's not like you drive 135+mph every day (at least I hope not). Your car should be fine until you reach those high speeds. I would just schedule an appointment with EC when you have free time and get it checked out. Maybe they will make it worth your time to come back if the EC facility is not near you.

aggies15

That was my first thought when I emailed them a few months ago and never got a reply. Houston is 4.5 hours away so it is a little bit of a commitment for me to drive all the way there and put 500+ miles on my car.

I almost I

Ok.

"every time I break 135 mph, it will overboost and check engine light will come on."

So they asked you to send the codes next time it happens and now all of a sudden replicating the issue to to much for them to ask? What's the problem? You make it sound like you do 135+ all the time in the first post, but now not so much.

aggies15

No, I do not break 135 regularly. The few times I've done it resulted in CEL so it kind of discourages me from doing it again. If you got a CEL every time you did something, how often would you do it?

Me saying "every time" does not indicate that I do it often, contrary to your understanding of it.

loungn14

I did, and as indicated multiple times we are requesting to read the car off and let us know of codes present. Most likely they will still be there in pending state or recorded state. Also, I posted what I wrote, not the pm. If you would like help we are glad to and will work as hard as possible to do so, but I am not going to play wording games with you on the matter.

Once again, we need the codes off the car so we can troubleshoot. Without that data, it is nearly impossible to see what is happening without the car in house.

exactly.... I can only offer so much help, without any effort from the other side this is a pointless endeavor.

aggies15

Looks like we're finally getting somewhere with a solution instead of a retort.

DameMD

Just saw EC's Post. I take back my reply. Good job Loungn14, in following up with a customer!! Looks like you guys are working out the issue. I will keep you guys in mind when researching tunes for my GLC43.

DameMD

loungn14 - I am looking at your tune and may take advantage of the current May sale. I have some questions for you before I make a decision.

1) On your site, you show GLC43 tune stock power at 362HP and 384LB-FT of torque. After EC tune it should be at 460HP and 528LB-FT of torque. The graph you show on page 1 doesn't seem to show those numbers or am I reading the graph wrong?

2) Biggreenogg stated that he went to your facility to get a tune on page 1 and before and after tune only showed a plus 40hp+ and 70+ tq. Why is his tune so much lower than advertised #s and he was on a dynojet?

If I plan to get the EC tune I am going to ISP racing in Maryland to do a before and after dyno. I just want to make sure I wont be disappointed. Thanks!!!!!

I made an acceleration video of my car doing 0-110mph w/ a Eurocharged tune. It's been 2 weeks since I got the tune and no issues at all. Overall, I am happy with the tune.

DameMD

Man your car is moving. Did you do a dyno yet? I still want to see the before and after numbers before I take the plunge. All the tuners are claiming such-and-such gains but the dynos are not backing them up.

Can someone respond to my post above regarding my questions on numbers?

sales@eurocharged.com

Okay, I was confused for a bit. But I think I understand what you're asking.

The numbers on our website are CRANK horsepower numbers. The numbers on the dyno graph posted are WHEEL horsepower numbers. There's a 15-18% drivetrain power loss when converting crank to wheel. (:

Oops.

RTC450

Not impress, i do the same with the dinan tune, please go to a dragstrip and clock the time to see!!!!

DameMD

All these tunes out here and I only seen OE and AMR verified on the track. I think AMR fastest time by user was 12.2 and I think I came across someone with OE at 12.3. Pretty darn close, and at least we know they are making said power. I hope someone with EC tune that has been to a drag-strip can chime in, $850 for tune is pretty good.

ShazV6

You would think so that AMR would be best. But keep in mind that from what i saw the best from AMR was a 12.2 @ 112 yet oe tune (uptownman) yielded a 12.2 @116 mph. That is a 4mph more trap over the AMR and the OE tune is half the cost of theirs. That 4mph is a good amount of lengths if you ask me. People need to keep that in mind. I know where im going for my tune. After seeing the videos think ill be going with OE tune paired with Weistec DP.

sales@eurocharged.com

We have a C450 here in town in Houston running 11.9 at 118.95 at Royal Purple in Baytown (-: getting time slip for you now! Just shot him a text

ShazV6

Whoa Whoa Whoa!!! Please post this up!!! Why you holding out on us!! You sir have changed my mind lol

DameMD

WOW that is fast but it looks like EC just trumped that. I am subscribed to this thread and I got the EC notice as I was replying to you lol

DameMD

If this is true I am sold. Waiting for time slips.

Also, was said car stock besides the tune or did the car have downpipes and/or exhaust?
