Porsche 996 Carrera ECU Tuning Write Process VRTuned.com April 11, 2016 Product Info, Tuning Tech Even though the Porsche 996 has been done since 2004, it is still a very hot car to modify. Our customer Tom has this 2004 996 Cabriolet which he wanted to get more out of along with his other mods. The tune is all done via the OBDII port. Reading out the car, sending us the file, then writing the tuned file once he receives it back is a pretty simple process. Tom even documented the process with pictures for us! After the file was loaded to his car, Tom told us, “Just took it out…Outstanding! Much more responsive.”. Ready to get your Porsche tuned? Shop all VR Tuned Porsche Tuning Here.
