Fabia 1.9 TDI PD AXR 74kw - EDC15P need better tune

Postby 1komma9pd » Sun Mar 09, 2014 1:23 pm

Hello,

my fabia was remaped some years ago but now I think it could be done better. After 1500rpm the punch was extreme and as VAGEDCsuite told me, 349NM way too much I think.
I've attached a VCDS log and the tuned file and as I see, the max boost goes to 2254mbar. When I put my foot down, the turbo spools up and the boost climbs too high I think. After a second, the boost is in the limited area.

What do you think about consumption? Is it possible to lower the consumption under 2000rpm? maybe an eco-file?

You have to lower torque limiter below 2k rpm, and lower P parameter and increase D parameter of PID controller for N75 valve. Sometimes lowering the boost map or N75 map (or both) helps too..

Didn't look at the dump, I'm just talking from my own experience...

Attached is a PID calculator that I'm working with (just to get the idea) - the most important factors are P, I, D, mass (approx.) and time step.

low rpm tq limit and dw map change, solves the problem

Why are the iq values so different?
SVBL Boost Limiter is set to 2350 ... in my logs sometimes it goes over this value a little bit .... but I didn't found this high values of boost in the maps

So now I've done my first file, with some modifications from the original tuned file
The curve in vagsuite tells me round about 300NM and 127HP @ 3000rpm
I think, my tune is more elastic and there is not the strong punch as in the original tune

codebank 2 (manual) = my own values
codebank 5 (automatic) = original tuning file values

What are you thinking about my first tune?

it's bad mod, bad for the clutch. If we belive in vagsuite dyno 1500 rpm 350 nm ? higest torque should be 2200-2400 rpm.
