I have succeed 400Nm setting with this car, but manual gearbox, If You like I will share with You with soft or information as You prefer.
At the other hand, I'm driving for 3 years with no problem, 60k km car has made after mod but now I stuck with regen mode with no clear cause. My question, Can You check my fap off solution?

I must admit that car is going well but after his got target temperature and (thats is importat) I drive gentle - regen happens, catastrophic amount of smoke, only stop car for 1-3minutes can brake this. If I drive car dynamically that won't happens.
Why it works for three yeares and now start to make problems?

Regards

Hi mate!!!! I think I can help you with dpf, but I need help with 400Nm and no more boost than 2450mBar.
Map sensor linearización I have found and voltage values, and I have a new one 3.1 bar.
I want a little more boost and I don't know where is my limitation. Upload tour file.I Will load mine.
Regards!!!!

I`m not at all good in that matter, just browsing out of interest but I think you should be able to go even over 400Nm..
The issue is the gearbox ECU and if my memory serve me well, there should be modified some parameters in the gearbox ECU to achieve that.

Good evening! I've been tuning for almost 2 years, and I started with delphi dcm 3.4 (also from a citroen c5 2.0 hdi 140 manual, year 2009), and now, I'm thinking of doing "multimap" I want to ask you, have you tried doing multimap? I brought the car to stage2 + custom, limit 420nm (at one point, I gave it a limit of 500nm, but it seemed a bit much to me, and I went back to 420nm), the car also has internal modifications! and I want to do multimap, because the afr ratio is very rich and it emits black smoke, and if I could do it with multimap, when I press a button (for example cruise control) the map would change to be 100% stock, or at least not emit black smoke! Thanks in advance!
