Took the Florida beast to the local Benz service facility here in Germany yesterday for filters and an update to the ABS - - - and yes I told them not to re-flash the ECU. But that's exactly what they did. Yes they apologized, however bye bye RennTech with speed shift and all the other maps. Do any of you know if any of the reputable tuners have the ability to re-flash online? I have full access to SDS with developer mode.

 

I'll probably just send it to Kleemann in Denmark (next door). They have a great reputation.

 

Why dont you send it to renntech since you paid for there tune to begin with?

 

Since the dealer has agreed to reimburse the cost (less shipping), Kleemann can send the ECU back top me the same day for s total of 3 days of down time. If I feel the Renntech is a better tune, then I'll have them re-flash it when I get back to FL. All of the top experienced tuners are pretty similar. There are no secrets.
