Hi to all guys, and by the time I head everywhere but I can't find any help...
My golf 1.9 tdi 105hp(the original) ? a woman and proving cycle to all of the effects shown by the fact that every so often, indeed very often ? moody...with the change of the temperatures of a few degrees change in noise/performance/torque/pulling power and at this point browse to rotate the boxes when you ride...Mind you, the days that okay ? a pleasure to ride, silent,smooth, pulls at any speed even with a little gas...then from one day to the other becomes noisy, rough, climbing turns, and almost a little boost and to take a speed I have to crush a lot of the gas...
That said I suppose there are maps in the file that vary in power with the change of temperature or atmospheric pressure...I tried to comb through all the maps, but with titanium but, unfortunately, the wrong values in the axes do not understand anything and I ask the more experienced or who can know it if I focused on that map tap to go turbo/injection/ always the same....
I can think of to bring all the maps and turbo pressure including F. temp at the same value, but I don't know if it is correct....
thank you all in advance...

before you do, check the sensors on the machine, temp sensor , maf, map, etc., and true that has maps that act on the basis of the temp, but if you have a sensor that info wrong here is that the ecu corrects the info in the wrong way. nn has the sense of touch maps turbo, at least that I want to make him a mod.

thanks for your advice jolidj... then the maf I have changed little while the map does not show any sign of wear and tear, values from vag in the norm ...I checked the machine from top to bottom, starting from the installation of depression/ turbo / injection etc etc..... the egr I have properly excluded from the map with a constant value from vag to 95%..... Accurate even with the map mod. in general the car is 1000 times better pero he always changes ...to-day, and silent and pulls..days becomes rough and should be less...

I also have the same problem, there are maps, as a function of temperature and of atmospheric pressure that cut diesel and, therefore, the boost. So if you don't unlock the ones you will always perform differently according to the variation of pressure and temp. Especially when the f? very hot you will feel the car much more? slow. Unfortunately, the difficult thing ? have the damos cos? you can identify these limitations and to change them but with a lot of forethought, why? ? dangerous to play with these variables on a car where it has also intervened on the mechanics.
