About Continental SDI9 tuning
The Continental SDI9 engine control unit is supported in 3 models from Porsche. We read, modify, and flash it with AutoTuner, then verify the result on our Dynojet 424xLC2 in Jenison, MI. A custom calibration optimizes fueling, ignition timing, boost, and torque limits for your exact build.
