Hi all! I recently bought a Citroen C3 1.6hdi 80kw from 2009 with edc16c34 ecu.

I read the ecu with MPPS V18 and ran the file through programs for EGR and DPF delete and wrote back the new file.
It works really fantastic and the car feels stronger and smoother and fuel efficiency seems to have gotten 12-15% better. Now running 3.8L/100km instead of 4.4L/100km.

I am however curious as to how much these figures could be improved by fine tuning the ecu. I have started looking at the files in winOLS trying to get a better understanding and find the relevant maps. I would like to find the injection timing and try advancing it for better efficiency.

It all is a bit overwhelming and I am finding it hard to make sense of it all. I have found some map packs for similar cars such as C4 and some Peugeots with same engine but I am unsure if they are relevant to my ecu.

Sorry for the long post but any help and pointers to which addresses needs to be mapped or confirmation that the map packs for similar cars are relevant would be highly appreciated.

Tried attaching my files but it says "The extension 6hdi 110ps dpf & egr delete is not allowed."
Are we not allowed to share these type of files?

Best regards
Ecu newbie

From desktop I was able to attach my original file and my current file with egr and dpf delete if anyone wants to take a look.
