Alfa OBD2 PID list also for Fiat?

Post by htevents » 02 Nov 2020, 14:10

Hello, I really hope I get a response this time, but I need help with this to finish my project.

I searched a lot on the internet about specific OBDii PIDs for Fiat, especialy of my Punto 1.3mjet +2012, but there is almost no info. Then I found a list of PIDs for Alfa. Are those PIDs the same for Fiat as they are from the same manufacturer and often use the same ECU in Alfa and Fiat vehicles.

The list I found (it is a long list):

Are these PIDs the same for Fiat?
Problem is that I don't have a way to test this. I am planning to buy all the components only when I think the project is able to be completed.

If someone has more specific PIDs they can share, please do.

I know that for Torque there is an extended PID plugin (Advanced EX for Fiat), but there is no way to reverse-engineer the PIDs they used and for example, apperantly it can read Turbo Boost Pressure from a specific PID instead of the standard OBDii protocol PID or calculated values. Problem is, I will not use Troque Pro for my project, but Realdash, so I need as much PIDs as possible to compleet my project, wich is a full LCD instrument cluster.
