You guys broke any drive shafts yet on your CLS fleet?
Just asking for the sake of full disclosure.
Nice run, but don't hate on the Canned tunes when Renntech uses them also. I don't care what they came on here and posted the information is out there for those in the know

Yes, Renntech will dyno and test and give input to the "canner" and the canner makes the changes and then supplies them back to Renntech in the form of a file. I know V-Tech does this too... so be it, but the fact of the matter is they are ALL loading "canned" tunes for this car. They do not have the ability to make changes while the car is on the dyno. The ECU must be removed from the car and opened and the file tweaked by the canner and then written to the ecu by Renntech, or Vtech, or whoever else is doing the tune.
The funny thing is, most everyone tuning these cars is using the same "canning company"

Peace!
You might have the ability to tweak and customise tunes on the dyno. Heck a dyno operator could do this. I myself with proper training could do it. Please dont come and say the tune files are produced in-house by you.
A while back you were getting your files from Oliver @ Evotech.

Now you mentioned you work with two software engineers. mind if you tell us who they are?

You might be able to tweak, change variable and customise tunes. However, the tune files are not hacked by you.
*Admins: I'm not slamming this vendor, just want some facts to be cleared for potential customers.
I see skinny's on the front of that car too

Skinny's were good for 2 tenths on my ZO6

You're right, can't trap 131+ mph with only a tune. It takes over 600 to the wheels to trap 131 plus in a CLS.
Its my understanding that the car has a tune, downpipes w/high flow cats (200 cell) and intercooler upgrade.
Stock air box, stock turbos, full weight, etc.
No broken driveshafts, but broke an axle shaft about three weeks ago. More people will experience this if they track their cars and make decent power with a tune.
The axle shafts appear to be a weak link.

Thanks for sharing the info. That's all the confirmation I need to keep my car tuned only. Canned, just the way I like it

Wasn't hating on canned tunes or V-tech. Just thought it was hilarious that uninformed people are throwing around the "canned tuned" terminology when they don't know their a** from a hole in the ground.
As for Renntech, I know and observed how they tuned my X5M from scratch, and I have seen their operation. I think that you and other people on this board may be misinformed regarding how Renntech creates its tuning software.
I was not getting on V-tech, so take a deep breath..
The Best of Mercedes & AMG
Your post stated, paraphrasing, "if Vtech and Renntech offer similar results, and Vtech costs $1500 less, why wouldn't someone go with Vtech over Renntech?" - I offered a couple hypotheses as to why.
Personally, if I were driving a brand new CLS63TT or E63TT, with a newly released engine that tuners are just at the "tip of the iceberg" of figuring out, I probably wouldn't run a tune from a newcomer (no offense to Vtech or any other applicable tuners).
The admittedly subjective, peace-of-mind aspect of going with a longstanding AMG tuning solution like Kleemann (who might not even have a M157 tune yet, IDK) or Renntech would be worth the extra coin to me.
I tend to hang onto cars, though - some guys switch cars every year (or less) - in those cases, maybe the "longevity-risk" doesn't matter as much... as it'd be the 2nd/3rd/4th owner's problem to figure out.
What would be the point of getting a tune if track numbers and performance didn't matter? Apparently, it does.
Listen, I know exactly what your trying to say.
I know people want peace of mind by going with a trusted tuner like Renntech. I don't disagree with you on that. I think people could make up they're minds for themselves, and could go with whatever tuner they want.
Be it Renntech, Kleeman, ETC...
If you think its worth the extra coin and of peace of mind, then by all means go for it.

Probably not a bad idea if you don't want to break anything.
As an aside, back in the day, I enjoyed my "canned" Hypertech tune in my Grand National.

I guess we are entitled to disagree on some points, including how Renntech creates their software since I have seen what they do to create its software.
That being said, congrats again to you for your 11.3 runs on street rubber.

Also the driver in that vid doesn't look like he has much 1/4 mile experience. You're not supposed to your burnout IN the water
That car should be getting alot better ET.One thing to also consider is this CLS63 is a RT test car. Is the tune they sell the same tune they are selling customers? Is it a race gas tune because that makes a big difference. To me a canned tune means a tune thats conservative and applicable across all cars of that model that you can just mail in and get. A dyno tune is tuned to extract the most out of that particular car. Independent track results are more representative of what the end consumer recieves IMO. A test car can have more timing thrown at it and leaned out etc and may vary with the tune thats sold.

In post #55, you said "at the end of the day, it's all about the numbers" - I simply disagreed with that premise, because there are plenty of subjective, intangible reasons someone might pick their tuner based on something other than simply "the numbers."
So, to reiterate, it might be "all about the numbers" to you, but respectively, it's not "all about the numbers" to everyone.
Also, saying "it's not all about the numbers" isn't equivalent to saying "track numbers and performance [don't] matter." I'm sure you understand, but if not, PM me.
Well said, hooleyboy. Agree 100%.

My ZO6 is dyno tuned which gave it much more power than a canned tune, but that doesn't mean I could put my ZO6 tune on any other car. It would mean disaster. So basically "canned" tunes are safe for the masses and not such a bad thing.

No need to over analyze these things.
Another way to determine when someone has a "canned" tune, their exhaust smells like StarKist!
We do have the ability to do custom tuning which would require you to bring your car to our dyno facility in Lafayette, Louisiana. If anyone is interested feel free to contact me at any time.
Kindest regards,

BlackBenz, I knew the you wouldn't be able to help yourself from chiming in.
When did you become an authority on drag racing. Remember you claimed that you hadn't been to the track in years, and also claimed that your car was going to run 9s at your track rental; unfortunately, you couldn't get out of the 11s. The only thing preventing your car from running properly was your boat load of excuses..."my car was backfiring"... "I didn't want to break an axle"...on and on.
Also, the driver of the car that you are ridiculing like a child owns Renntech, can buy and sell you a 1000 times over, and doesn't need your approval. Even the way he drove the car, he trapped more than your stripped out sled has ever trapped.
Must I remind you again that you couldn't lay off your keyboard long enough to get your skeleton of a CLK to run properly for your track rental, and now you pipe-in when you don't have a clue as usual. In addition, you showed your real colors when you backed out from attending my track rental to prove up your babble, even though I agreed to pay for your trip.
Also, .2 tenths from skinnies - you are dreaming. So let me get this straight, in your mind putting skinnies on a car means its not full weight, but you can strip out your CLK, including the seats, and you claim it is full weight. What a clown.
Regarding the "race gas" tune that your claiming Renntech is using that it doesn't offer to customers (according to you), I guess that would prove that RENNtech doesn't use a "canned tune".
Sell your back-firing, stripped out sled and get a new 63TT Benz so your comments might have a sliver of relevance in this thread.

. It's a shame because they have run some incredible times with their cars. Unfortunately they have left themselves without much credibility. Oh well, life goes on I guess...........
