Nowhere I'm my post did I say your warranty will be denied because of Renntech. I said YOUR CAR WILL BE FLAGGED FOR HAVING A RENNTECH TUNE. Your warranty will still be honored. Nothing changes except now most if not all MB dealers will know you have a tune. He even showed me where on his screen the flag shows up. T
That being said, he also added it was for any car that gets the tune from a dealership. It's something new they are doing and he believes its just a way for MB to compile data. My car is NOT flagged because I got the tune back in 2015 and that was not in effect back then. Now if they have to send my ecu back to Renntech to get reflashed for whatever reason, it will get flagged then.
I didn't get tuned yet but I asked my dealer if I remove my computer myself and send it to Renntech they will not honor my warranty , But if you let us send the computer out to Renntech we will give you a loaner car and reinstall for free.
So it seems like a no brainer, What other car manufacturer honors such a mod and doesn't void warranty?

WOW how nice of them to reinstall for free lol
from my own experience I came to the dealer for oil change in s/c SRT8 , they ask me to rev it and what not , bottom line the manager said what ever I need in terms of warranty . Same was with audi at VW dealer , they knew I'm stage 3 . It doesn't apply to an manufacturer , it's more about the dealer him self .
anyone definitely can tell it's modded

I hear you on it depends what dealer because there a guy on YouTube with a Hellcat his supercharger bearing was failing it's a manufacturer defect , anyway he had a air intake and they void his warranty and black fagged him to all dealers ,was going to cost him 12k to fix , but he finally got it fixed under warranty but he went through a ton of red tape
because i did a big smokey burnout (like the one in you signature) in the dealership parking lot while yelling "RENNTECH BIATCHESSSSS... *** YEAH LOOK AT ALL THIS RENNTECH POWERRRRR!!!!"
i kid i kid.... they know because i told them when they were working on a low fuel pressure issue that was causing misfires and they sent the ecu back to renntech as renntech had a fix for it

not sure how is it 12k if BNIB supercharger is 8k , used low miles 4k
So it seems like a no brainer, What other car manufacturer honors such a mod and doesn't void warranty?
Because no car manufacturer does. I was explicitly told, by my MB dealer in MA that is a renntech dealer, who called MB USA (on my request to confirm or deny any warranty implications) that if I bought the tune, installed it at the dealer, and I had issues with the motor, trans, axles, etc. I would NOT be covered any longer. So in my case it DOES void the warranty so it's a no brainer for me - I won't do it until I am out of warranty
Now, if your dealer decides itself to honor your warranty that is a different story. Seems like that is the story with kponti, but I wonder if he blew a motor, trans, etc. if the dealer would go so far based on what I was told MB USA wouldn't honor in my situation.
I posted about it in the W212 section (I have an E550).
back to my point earlier, this is why BMW and AUDI is faster... over there you introduce a thread about new turbo upgrades showing promise at over 750+whp and they go nuts over it... meanwhile on the MB site it turns into a warranty voiding discussion
Yep, because we're all so afraid of our machines and can't just leave well enough alone
It's funny because Audi is the WORST with warranty stuff form what I read. That said - we are in a forum section where a lot of cars are still covered by a warranty - in 5 years when everyone's been out of warranty for a while you'll see it pick up like the E55's have.

yes audi is the worst about warranty voiding by flagging, yet their owners still mod more and dont worry about it = why they are faster
MB uses some of the cheapest parts of the German manufacturers and yet they charge waaaay more than most of the others. Wholesale to retail price on MB parts vs BMW parts show a larger disparity with MB most of the time. IE your crap will most likely break, but it will cost you waaay more to buy the part with the Mb sticker on it.
That being said, if I had gotten the AWD M157, I would be sending my stock turbos to Pure by now. I may still do it anyway.....
What i am getting at is that the probability of something minor yet taking long as hell and costing way more than its worth is a matter of when not so much if with AMGs. Most bouhgt this car to carry around kids etc etc, it is simply inconvenient to have to deal with dropping your car off cos something broke again and waiting to see if it is covered or not because of a carbon fiber hood

I can appreciate it - I'm a GM guy, the first thing you do when you buy a Camaro or vette or anything with a V8 is put an exhaust on it That plus when it breaks you can work on it.
With my E550 though, I don't want part of dealing with an warranty issue based on the cost and complexity of working on it

we could only dream of the aftermarket support of vette... just watching some of the Vengeance Racing C7 Z07 ProCharger F1-X 1050+whp bolt-on Conversions makes me want to convert to GM guy vs euro car guy if only the domestic performance cars could step up their interior i would be all over it (cadillac is getting close)
I always just enjoyed being able to go to a local auto parts store and getting exactly what I needed to fix anything that is broken. I'm sure that's different now with the newer GM stuff, but I hear with an MB if you buy anything other than the most expensive part at an MB dealer at an insane markup it voids your warranty :P

My friend just bought a brand new S3,he is going to mod it with floating brake rotors ,rims , and intercooler, he wants to get a APR tune but he knows if they plug it in they will detect tune and automatically send a flag to AUDI CORP, and his car will be flagged and his drive train will be void, so for now he's not doing ****
FYI All Renntech tuned cars are now being flagged on MB's database. So anywhere you go, the dealer will know right away if you are tuned or not.
Just wanted to update this post. It's called a status 8 flag. If you have a Renntech tune, falls under that. Not sure what that means but dealer said if there is a problem and MB wants to trace the origin of the problem, this will help decide whether they or Renntech covers is
May have missed it in the original thread, but what are these guys doing to protect the tranny? Are these cars going with upgraded trannies / clutch packs? Or are they just rolling the dice?
These numbers are no doubt appealing, but I don't want to grenade transmission after transmission just to run it.
Transmission might not explode. The issue is putting that power to the ground. In my own E63 with stock ransmission if I put in 5th or 6th gear manually and mashed the pedal the clutch would slip. I didn't notice any clutch slippage in automatic shifting modes. But when Eurotekk read the engine computer told me there were codes that he thought represented power cut due clutch slippage. He read out the odometer values associated with those codes, basically corresponded to every time I mashed the throttle. These did not produce any engine check light or any error on my own ond2 scanner they could only be seen by reading the computer with the mercedes ecu reader.
i doubt transmission would blow it would get slippery with time depending on how hard you drive it and you would have clutch particles floating in the transmission oil and then things would probably go downhill from there.

yep, i heard the same. mercedes flagging tuned ECU's (renntech included) as Status 8.... this is basically the same thing audi does with their TD1 flag

Keven just tuned another 800whp E63 turbo kit. We're (he's) finally getting some some good numbers from this platform. I sure hope these numbers translate to the strip/street!
yeah just saw it and this time it was on the AMS turbo kit, so looks like the turbo kits that were already out there were pretty good too, just needed the right tuning since out of the box the AMS kits are making only like 680 whp... so looks like with the addition of wiestec downpipes, meth and the right tuning it jumps to 800whp ...... they also got the CLS up to 847whp (forced performance turbo, not pureturbos)
I suspect that the methanol in addition to cooling is supplementing the already maxed out fuel delivery system. That's why only the methanol cars are producing these numbers. If the methanol finishes all of a sudden you are lean and that could be the end of the motor. Our cars do not have a reliable way to save the motor if methanol runs out or fails. I believe we rely on the knock sensor to do that. It did not work for me. You lose your motor and a new one cost 60000 euro.
I would not recommend relying on methanol injection as a fuel supplement. I believe thats the direction W4 is headed, hence their claim that methanol can add 100 horsepower according to another member of The Forum. On our platform methanol should be strictly for cooling and the car should be able to run safely without it unless somebody comes up with a nice Fail-Safe for the M157.
Hard to give a precise figure for example 1 in 10000 runs or something like that. It's common enough that if you search for it on Google and forums you will find people sharing their stories.
Before the days of direct injection it was easy to put a bigger fuel pump or accessory fuel pump and bigger injectors and adjust pulse widths multiplier. That's what I did with my Trans Am. As far as the fueling is concerned the car runs just like stock with power that is beyond what the factory fuel system can deliver.

That plus when it breaks you can work on it.
