ECU tuning & bubbling Maserati 4.7 V8 NA Quattroporte GTS Also installed on naturally aspirated!

Hello! This time we are installing ECU tuning and bubbling on a 2008 Maserati Quattroporte GTS 4.7L V8 NA engine! We traveled to Saitama for the installation!

As this is a late Maserati, the ECU is in the engine compartment. If you remove the cover as shown in the picture, you will easily find an aluminium box-shaped one! Once removed, you can pry open the stubbornly sealed ECU.

The ECU is fixed and the data is sucked out. This part was quick and only took about 5 minutes. We analysed the data and tweaked the ignition timing, fuel, etc. From the start of the work to the end of the test run, it took a total of three hours! mbFAST Tuning does the data preparation and other work myself, so I don't have to leave the car with them. I have been told that bubbling is not possible on NA engines, but since I rewrite the data myself, bubbling can be achieved. We will install it until it sounds right, so don't worry. Please refer to the following video!
