Maserati Quattroporte ECU remapping
35 files available
About remapping
The Maserati Quattroporte accounts for 35 files in our catalogue, spread across the 3.0 V6 petrol in its turbo and GDI variants, the naturally aspirated 4.2 V8 of earlier generations and the 3.0 diesel. It is the marque's flagship saloon, and whoever brings one in wants refinement as well as pull.
Stage 1 accounts for 29 of the 35 files, with 5 Stage 2 for units with modified hardware. There is practically no maintenance work: the profile is purely performance-related. The ECUs are the MED17.6.9 and MED17.3.4 on petrol, the EDC17C79 on diesel and the ME7 and ME9.1.1 of earlier generations.

What is gained on an already very powerful saloon?
The factory calibration on these engines leaves margin for range-positioning and homologation reasons. The improvement shows above all in mid-range delivery and throttle response.
Do you work on the naturally aspirated 4.2 V8?
Yes, it is present in the catalogue. Being naturally aspirated, gains are more contained than on the turbo units and show more in response than in figures.
And the diesel version?
The 3.0 diesel is covered with the EDC17C79 ECU. It is the option with the most torque available at low revs across the whole range.
