Porsche 991.2 Carrera 4s ECU tuning and bubbling spec installation made it faster!
We have installed an ECU tuning and bubbling specification for a late Porsche 991 (991.2) Carrera 4s.
This Carrera 4s was delivered the day before the installation, and he immediately asked for a tuning. We had done the work on another car before, and this is a repeat!
-

-

-
The minimum time is 1.5 hours.
-
How do you rewrite it?
-
In the case of the 991, the installation can be done via OBD. Most Porsches are located in the left-hand fuse box, regardless of the position of the driver's seat. Data can be read and written from this OBD.
Once the tuning data has been created and the bubbling has been included, the first data is installed for the first time. Only the first time, the write time is about 20 minutes.
In case you're wondering, you'll see all kinds of warning displays like this while you're writing. (Don't worry, it's business as usual.)
The owner drove the car and confirmed that it was faster. However, we had to rearrange a few things from here, and also take into account that bubbling can still break the catalyst at high revs, so we reinstalled the data with 5000 rpm and above turned off. (After the second install it only took a minute to complete.)
