Do Renntech dealers have the ability to do the ECU upgrade on site? Or do they have to send it to Renntech corporate to have it done for them?

I believe they need to send it to FLA. Who are you considering using in S. CA?

I found this Renntech shop:

German Imports
San Juan Capistrano CA

Does anyone have experience with these guys?

You have to ship the ECU to Florida or Arizona.

I've been to his shop before. Stephan is the owner and he knows his Mercedes and Porsches.

He can do the ECU coding on site.

I have not had the best of luck with them however. They were not able to fix the problems that I had with my car.

For bolt on items, they are great.

Actually, to be exact, all major RENNtech dealer have the ability to flash the ecu on site.
