superlubricity

Looks to be a bit more widespread. Mperor, drawde, justthebest, mrc63jg, & Dr_jitsu have Eurocharged tunes and each has experienced this problem. Hope it gets remedied quickly.

Dr_jitsu

well, we ran a diagnostic and could not find anything wrong, no problems today and I put 65 miles on her.

One interesting thing we did find, the diagnostic said the car had 1134 miles although the OD said 734. Apparently MB puts 400 miles on the car and sets the OD at zero.

BerBer63

Or you bought a used car that was hacked ??

Dr_jitsu

Doubt it, MB Sugar land has a pretty good rep.

Hans Delbruck

There has to be a fault with that diagnostic tool. 400 hidden miles? Don't believe everything you see.... or don't see.

734 mi. = 1181.258 km Are you sure it wasn't set for km and you misread it?

Speculation, I've has their tune since Nov ver 1 and the newer one loaded Mar 2010. Never had a problem. Some pretty good highway runs not even a hiccup. There must another variable.

superlubricity

I'm just citing a factual commonality. Others also picked up on it. You don't see any Kleemann or MHP-tuned cars bringing up the same issue. It also appears to be a known issue with early Powerchip tunes.

I wonder what other factors are at play here. It would be great if someone could prescribe a precise play-by-play for replicating this symptom. Not everyone drives the same so this may never surface for some.

Based on findings by others the Paddle Shifters are part of the equation. Do you use yours?

RStevens63

I'm inclined to agree with superlubricity, that's far too many tunes for the same make of car from one tuner that are experiencing the same issue. 2 cars is questionable, 5 on one forum at one time is kind of like a red flag? Then factor in that no other tuner is having the same reported problem presently. Even if there are other variables the commonality is a car dying on the highway, which is a rather large safety issue, and having been tuned by the same tuner.This isn't about whose tune is better or not, it's about which one won't leave me or my family hanging out to dry when I least expect it. After reading this I plan on spending at least $1495 on my ECU tune. Thank you to those that shared their experiences!

i had my eurocharged tune for about 18-19 months and never saw this problem nor the other problem i read in another thread but apparently that was taken care of by version 2 of the tune.

either way, i hope with all the great people on this forum coming together on this, we'll be able to pinpoint it and get it corrected.

i drive in all modes. after being on this forum, i almost feel like i'm the only one who drives in C. lol... but i switch from all 3 depending on my mood...

Rest assured that I'm here to resolve any issues guys.

Has this happened more than once to anyone?

RStevens63

I applaud your customer service efforts, they are no question outstanding.On the other hand, I would think a reputable tuner such as yourself would at the very least stop selling their tuning for this particular make and model until such a large potential safety issue was at the very least understood if not completely resolved. If the problem is as was previously suggested something seen in early versions of tuning, perhaps they should be a bit more refined before being released to the public?TIA

sales@eurocharged.com

Thank you for the kind words and I understand your point of view. I have done some research and it seems that non-eurocharged customers have experienced this as well. It doesn't seem to be limited to our software at all.

This thread seems to have the issue described and also the fix is listed.

What I would like to know is if it has only happened once or has anyone experienced this multiple times.

Our Star DAS is being shipped down from Chicago so I can look through Dr. Jitsu's ECU with an OEM diagnostic tool. I will work very closely with Dr. Jitsu this week and we will try our best to duplicate the problem.

Some customers have over 8,000 miles on the tune with 0 issues.

Thank you all.

justthebest

Happened to me twice, but it hasn't happened again after the dealer installed a new accelerator pedal assembly.

I have the Eurocharged tune and have not experienced this at all. Tend to drive the car fairly hard around town but have not tracked.

PetroC63

I've never experienced this problem.

My original tune was done in January and had a re-flash
in June. I drive the car pretty hard and use the paddle
shifters often.

Vegas_AMG

So where's re retraction from you guys? Quick to criticize but not so quick once the real issue is discovered. Connecting the dots and making conclusions should only be done when one has all of the evidence not a superficial single commonality.

superlubricity

You are jumping the gun a bit and I certainly wasn't criticizing.

It looks like some have found remedy in replacing the accelerator pedal. Awesome but that doesn't identify root cause. Was the failure a result of the tune? Looks like Eurocharged is still looking closely at the issue. I don't think this is solved just yet.

RStevens63

I would expect a retraction when one is warranted. So far not all the cars in question have been remedied by the alleged fix. You think you have all the facts? Obviously not, you're just taking the word of the tuner in question which is understandable since you have the same tuning. However you're muddying the water saying the issues have been resolved when they haven't. Until new pedal assemblys fix the problem in all affected cars the commonality still exists.

GHAZAN

Retraction for what? I didn't see any negative criticism, just pointing out the obvious unusual pattern of occurrences that anyone would have noticed. It'd be nice to have all the evidence, but most problems in life don't present that way. It's an ongoing process....

Guys does anyone solved this issue? i have a friend with the same problem, he changed the pedal accelerator twice and he reflash to stock ecu and the problem does not go.

Dr_jitsu

My car has run strong ever since w/ no problems.

In my case I think it was a torque/rev limit issue related to the break in period.

Robert AMG

iTrader: (1)

how did you solve it?

RStevens63

Dr. Jitsu,

You were told it was a break-in torque limiter? I wasn't aware those existed on any car?

Dr_jitsu

They can be programmed in. Didn't do anything to the car, just kept my foot out of it for the rest of the break in and at nearly 2K miles have had no problems.

Are you currently having this problem or just stirring the pot?

RStevens63

My car is stock and I do not have this problem, nor do I want it, which is why I'm asking questions to those that have it. It's not something I want to put myself or my family through, which I'd hope you can understand.

I'm not sure what I would say if someone told me that there was a break in torque limiter on my car when I knew there wasn't. I have called MKB and Renntech about this problem and neither had heard of it, both also agreed there is no such thing as a break in or mileage based torque liimter in the 63s.

Take it fwiw.
