SL55/63/65/R230 AMG: 2007 SL 55 ECU Tuning
I am interested in tuning my 2007 SL55. I was told by the dealer, that the tune will show up on the computer diagnostic print out, under the "version" #. I have a great relationship with the dealer, however, when warranty work gets submitted to MB, they may reject claims because of the ECU being altered.
I heard of a small "matchbox" type device, that will allow for the driver to send the orginal file to a tuning company, then the company will email back a tuned file, which can be programmed to the small box, which is plugged into the OBD port.
Does anyone know who has a reliable tuning device, that plugs into the OBD port, which will allow me to go between the original ECU programming, and the tuned programming???
Thanks in advance!
