Porsche 991 Carrera ECU remapping
6 files available
About remapping
The Porsche 991 Carrera accounts for 6 files in our catalogue, split between the 3.0 DFI Turbo of the later phase and the 3.4 DFI naturally aspirated of the earlier one. It is the base version of the 991-generation 911.
Stage 2 leads with 4 files against 2 Stage 1. The ECUs are SDI21 and SDI9. The two engine generations respond very differently: the turbocharged unit has far more headroom.

Which engine gains most?
The 3.0 DFI Turbo, by a clear margin. The naturally aspirated 3.4 gains considerably less, since there is no boost to adjust.
What is Stage 2 for?
It is for cars that already carry hardware modifications, typically exhaust. Without them, Stage 1 is the right level.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
