From my experience with LPG conversion kits that have a parallel ECU module with a separate proprietary diagnostic port, the LPG injection needs adjustment periodically, because the performance of the injectors drops as they get older.

What I would like to know is if the same procedure should be done to the factory fitted LPG system that's controlled by the one and only ECU of the car and that can be accessed by the car's OBD-II port. Does Fiat's official scan tool offer the ability of adjustment of the LPG injection map?

Hello,

I've checked in my 5.1 registered version of MES and it seems it is not possible :(

Those are the adjustments that can be done after connecting to the ECU:

In the actuators tab there are functions for the gas injectors available though:

But they are only used to activate the function to test.
