I've asked Hartmut if this new flash extends to other cars outside of the E55. This thread has me a bit worried as well even though I"m in a SLK55. 
Who knows if mercedes decides to extend this to other vehicles. I already know that the 2006 SLK55s have a bit different programming than the 2005s.
To be honest Ted, while I don't speak for Renntech, I would be highly surprised if Renntech was willing to reprogram a Kleemann car. I'd expect that Kleemann would also not be willing to reprogram a Renntech car. But who knows ... you are a customer that I"m sure Renntech would love to have. If not now than for the future.
Good luck to everyone with this issue I hope it gets resolved ASAP.

This is not an accident. Looks like MB is deliberately thwarting the efforts of aftermarket tuners. You do the recall work to your car at your own risk.

In my case, being in CA, we originally decided to put race cats in instead of removing the primary set completely. So, after the recall, mine should be just fine since the high flow race cats should do the job and not trigger anything. Those of you with working setups post recall / reflash... do you by chance have working primary race cats in your K2 setup?
Normally those are removed in the K2 setup unless you're in a smog sensitive place like CA, in which case Cory recommends the race cats. I suppose you could always retrofit and put them back in if you wanted...
Cory also found another way around it I'm not fully up on, but it involves doing the reflash while its in the car (Rock / Dave, you know what I'm talking about... explain it if you want... I'm gray on it).
So, I'm doing the recall today, then sending my ecu out, then I'll put it back in and let you all know.

Is this ECU reprogramming part of the service campaign #2006.03.0011? I just spoke to my SA and this service campaign is the only one for my car.

"For all Kompressor AMG models including SLR. Your car is not affected.
Also we don’t have any power loss, we were well prepared for this in advance since we knew it was coming for almost a year."
Guess I don't have to worry about it. Nor should the other Renntech owners ...

I am sure Helmut or Cory would tell you the same thing....you pay us full price, we'll mod the crap outta the other guys ECU.
Not sure how a Renntech ECU would run on a K2 car and Vice Versa, but the last thing we need is a Renntech Klee battle.
Let's focus on the real enemy...mother f'in Benz for trying to keep us from modding.
Benz is gonna learn real quick why we love these cars....hopefully not the hard way (sales plummeting)
I drive this car for the luxury AND PERFORMANCE. Get a clue Benz...cut this ***** out before this gets out of hand.
Sorry....just pi$$ed right now. I need a kill....be right back.

In a previous thread i said my e55 making 500rwhp,649 rwtq was scary fast.I did the recall,and the car still felt fast but was more controleable.......I took it to the dyno and it only made 467rwhp,and 580rwtq.
My a/f on top is running 10:1,but the car does not feel flat on top.

For people with K2-K4, I would not be overly concerned. Kleemann does have a couple of solutions for the problem. I had the new K2 software installed after the MB re-flash without a hitch and my car feels stronger than ever.
I would be more concerned if I had a stock ECU and MB was about to re-flash it. I hope we can get some pre and post dyno as well as track numbers from people that are stock.

.............lets not confuse each other. I too have been speaking with Cory. The problem is that very few people have actually dynoed their car after the recall. Everyone that has dynoed their car made less power except for one CLS55.
.........The consensus as I understood it was that the cars drove crapy after recall and drove much better after Kleemann re-flashed the ECU. So from that standpoint, don't worry.
..........the other problem is that actual dyno figures before and after recall. And the results are as I stated above.
.........If there isn't a problem why is Kleemann Denmark working on a solotion for a non-problem?
...........The G55 program is a whole other issue. My car is not even driveable now. I can't go past third gear............the car just stalls as the engine pulls timming.
..............lastly, why are you even doing the recall? To avoid a check engine light triggered by the secondary injection pump? Makes no sense. Everyone that has had a check engine light has been from the O2 sensor problem and the check engine light comes right back on as you drive your car out of the dealership after the recall. No check engine lighs from the so called secondary air injection pump have so far been reported by anyone.
............Finally even if you decide that the recall work is neccessary, there is DEFINITELY no reason to reflash your ECU in order to fix the secondary air injection pump relay.
............If you insist on doing the recall, I will suggest you make sure they don't mess with your ECU.

1) To keep MB and my service advisors from getting all uptight about these mandatory things they're ordered to do and
2) Because the new K2 program specifically requires the recall / flash for it to work. Cory can't provide the new "scary fast" program if the recall / flash isn't done. As MB changes these programs, Kleeman adjusts future ones to match that upgrade path. With all the moving around that happened, the new K2 program won't run on a non flashed ecu...
Loren
PS. Irony: While doing the recall work today, they discovered a portion of my SBC system was failing and needs to be replaced... so its in the shop for an additional day. By friday I should have the ECU back from Cory and will be able to accurately gauge this whole thing and vote in the other thread properly...

Does anyone know the details of the "new but crap" reflash program?
ie how do we tell if we have it, when did they start using it? Is it only US guys that have experienced deteriorating performance? or is it worldwide?
